How to fit Bridgestone summer tires. Asymmetric tires, left and right Tire design features

The season for changing car tires from winter to summer begins when the roads are cleared of snow. Studded tires are no longer suitable for driving on asphalt, as there is strong friction. When buying tires, you need to make sure that they are the same in everything (size, marking, tread pattern).

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe me? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

Summer car tires Bridgestone is available for different cars: from cars to heavy trucks. The range of models is large and every car enthusiast can find something to his liking. Some tires are manufactured according to the latest technology and enable the vehicle to move even after being punctured.

The tires provide excellent maneuverability in bad weather, help you save fuel and improve safety. Bridgestone tires are designed so that the shoulder block is mostly in contact with the road, and the tread provides good corner entry.

Types of tires and basic concepts

Regardless of the purpose of tires, be it tires for passenger cars or SUVs, they are divided into the following main types:

• Bridgestone symmetrical car tires. The tires have a symmetrical tread, cord and sidewall construction. Tires are less technical than asymmetric or directional tires. They differ in lower cost. The symmetrical tires provide good road stability. This is one of the main advantages. Disadvantage - tire performance and wet behavior cannot be optimized. This type of tire is intended for small city cars. They can be installed on a car in any position.

• Bridgestone asymmetric car tires. This type has a different pattern on the inside and outside of the treadmill. Each side is important when evaluating quality. The inner side of the tire with an open area for water drainage. It reduces the risk of aquaplaning. On the outside, a tread pattern is applied to which it stiffens, which provides stability when cornering and maneuverability. On the side surface of the wheel there are designations: "Inside", "Outside" and others. Asymmetric tires are more expensive than symmetrical tires.

• Bridgestone directional car tires. These are tires whose tread pattern has a strict direction. The direction of rotation of these wheels is indicated on the sidewall with an arrow-shaped pattern. The markings are usually "Rotation" and a drawing. This type of tire is effective on wet roads... In heavy rain, water drains quickly. The tread pattern improves motor skills even on snowy surfaces. These tires are prized among sports car enthusiasts.

Installation of wheels requires strict adherence to rules and conditions. Therefore, tires are divided into two more types:

• "Left". Installed only on the left. The wheels are marked with the word "Left" on the sidewall.
• "Rights". Installed, respectively, strictly on the right. They are marked "Right" on the sidewall.

If there are no such inscriptions on the wheels, then such car tires are not divided into "Right" and "Left". And it doesn't even depend on the tread pattern. Directional and at the same time asymmetric car tires can be produced.

One type does not exclude the other. But this is rare at the moment, as Bridgestone's Right and Left tires do not offer any advantages.

In the case when tires are changed at once in pairs, new tires with still unused tread pattern, it is recommended to put on the rear axle, and leave the old ones in front. This will enable the driver to better control the vehicle on a wet road.

Fitting asymmetric car tires

Set asymmetric type Bridgestone tires quite easy and intuitive. When installing this type of tire, the outside should be marked with the words "Outside" or something similar. For example: "Facing outwards" or "External". On the inner surface there should be an inscription “Inside”. The main thing is that the inside should not be confused with the outside.

While handling and traction will not be severely affected, manufacturers caution against using tires in this way, as this can lead to uneven tread wear, as well as increased noise and unnecessary vibration. During installation, the “Inside” inscription remains invisible, because it is directed towards the vehicle. Thus, a sign that the asymmetric tires are installed correctly is the visibility of only the “Outside” lettering.

If not correct installation Asymmetric tires are less controlled when driving. Care must be taken when driving with improperly installed wheels and do not exceed the speed.

Bridgestone directional tires must be installed so that when the vehicle is traveling forward, the wheel travels in the direction of the directional arrow on the sidewall of the tire next to Rotation.

As mentioned earlier, "Right" and "Left" car tires are installed strictly on their sides in accordance with the inscriptions on the tread.

Installing symmetrical buses

Bridgestone symmetrical car tires do not have an outer side, they do not have a specified direction of rotation and direction to fit. For these reasons, they can be placed in any position, as well as swapped without fear of making a mistake.

Improper fitting of symmetrical Bridgestone tires makes the vehicle less controllable when driving. Care must be taken when driving with improperly installed wheels and do not exceed the speed.

Start installation

The best source of information on how to properly remove and install tires is the vehicle operating instructions. It contains a lot of useful recommendations and tips.

The installation sequence is as follows:

• To remove old car tires, you must unscrew the nuts. It is advisable to use hand tools for this purpose, not power tools. It will be more secure. Wrenches are good tools, but not everyone knows how to use them. An ordinary wrench works best. The nuts do not need to be completely unscrewed, but simply loosened.
• The car must be jacked up and this must be done only on a flat surface. After that, you can already unscrew the nuts to the end and remove the wheels.
• New Bridgestone tires need to be positioned opposite the old ones. Tires should not be confused, because each must take its own position. For this we need pictures and inscriptions on the sidewalls of the wheels. Definitely worth checking wheel nuts and their condition. You need to loosen and tighten them. If there is significant resistance or any roughness, then such shortcomings need to be corrected before installing the wheels. There are thread restoration kits. They will help.

• Carefully clean the surfaces of drums and brake discs from dirt and rust.
• Check the fit of the wheel. The smallest deviation of the center of the hub from the center of the disc causes the wheel to shake.
• To check that the bolts and nuts match the thread sizes, they must be supplied without wheels. They should spin without using a key.
• The disc seats and bolts must be treated with an anti-corrosion agent. You can use a wax spray.
• If all the previous steps went well, then the wheels can be installed.
• This step passes the post-installation checks. You need to run your hand over each wheel and make sure that the edges of the rims do not touch the inside of the rim.

So, all the main types have been considered summer tires and how to properly install new tires on the car. If there is a fear to carry out the procedure on your own, then the correct installation of Bridgestone tires should be carried out by the masters.

The question "why did they bring me all four right (or left) asymmetric tires?" most attentive car owners ask when delivering tires.

Let's answer right away: "right", however, as well as "left" asymmetric tires are not produced at the moment.

A few years ago, Nokian had Nokian asymmetric directional tires (NRV model) that were "left" and "right". But it turned out that this decision caused a lot of inconvenience.

First, it made production more complex and expensive. Secondly, these inconveniences were due to the fact that it often turned out that only the left tires remained in one warehouse, and only the right tires in the other. Thirdly, it was not clear which one to buy. spare wheel, because no one knows which tire will flatten or become unusable.

Imagine a situation where you bought 5 tires, two left and three right, logically assuming that there is a curb on the right and there are more holes and debris that can damage the tire. By the way, according to statistics, it is the right wheels that suffer more often than the left ones. But, by coincidence, it was the left tire that fell into disrepair! And with 4 tires of the same model (one left and three right), you still cannot fit the car with tires.

It is for these reasons that manufacturers now do not manufacture left and right asymmetric car tires.

Then a reasonable question arises, it turns out that asymmetric tires, which are on the left, "work" differently than on the right?

Yes exactly. When identical asymmetric tires are on the right, then part of the water is thrown, as it were, inward and backward, and if they are on the left, then they throw water inward and forward.

How does all this work and does it interfere with the control in the rain? Numerous tests and studies largest manufacturers tires have shown that this tire design does not affect handling.

Asymmetrical tread patterns come from motorsport. And they still remain the most efficient at high speeds, especially in terms of good directional stability in turns and informative driving. It is asymmetric tires that are now conquering the car tire market. They have many advantages over symmetrical and directional tires.

1. Excellent handling of the car, due to the fact that the outer sidewall of the tire (indicated on the tire - outside), which is much more loaded in a corner, is made denser and with larger tread blocks. And the internal one, on which the load is much less, is, on the contrary, softer. This results in a good contact patch of the tire with the road and excellent handling of the car.
2. Spare wheel versatility. Unlike directional tires, asymmetric tires do not need to be reinserted onto the rim in the other direction when the wheel is mounted from right to left (or vice versa). After all, the outer side of an asymmetric tire put on a rim will always remain outside, both when installing the wheel on the left and right.

That is why asymmetric tires have become so popular and in demand, despite the fact that they drain water from the contact patch in slightly different ways.

Large companies producing asymmetric tires (such as Michelin, Nokian, Goodyear, Continental) carry out a huge amount of research, developing and testing various options for tire designs, tread patterns and rubber composition. Therefore, when buying tires from well-known manufacturers, you can safely trust them in this aspect.

The only thing is that after you have asymmetric tires installed on your car in a tire shop, it is advisable to check that they were installed correctly.

The inner side on the bus is designated INSIDE, and the outer side is OUTSIDE. Therefore, if on all tires (on the sidewalls) you, bypassing the car, see the OUTSIDE inscription, then everything is installed correctly (you should not see the INSIDE inscriptions outside the car).

Some manufacturers of asymmetric tires designate the outer side of the tire (Outside) as: This side facing outwards, Side facing outwards or External. And the inner side of the tire (Inside): This side facing inwards or Side facing inwards.

No, I haven't changed

The topic is complete nonsense, even for idiots it says INSIDE AND OUTSIDE on the rubber

This is a difficult story.
Here's a similar one:

kirillkzn
But it will become higher by the 20s)

Novaman
Like this?)

Kirillkzn
I have summer 18s add clearance decently after winter 16s)

Novaman
In general, it's strange, they shouldn't)

Sonic-sonic
There is such a thing. if there are more wheels)))) Tire calculator solves and dispels in such cases
Only to "decently" increase the ground clearance, it is necessary that the wheels are decently larger in the total radius))

Kirillkzn
The tire ones will not work here, he considers the tire purely, but you also need to take into account the disk itself. I have only a couple of mm on it on the tire, it turns out the difference, in fact, the car becomes much higher after the winter, with the suspension unchanged, I think at least 1 cm for sure)

Sonic-sonic
winter tires are much softer, from this to a centimeter error. Also, if the rubber is worn out, the overall radius of the wheel will change. Well, from the realm of fantasy - if suddenly a person mistakenly put tires that were not designed for the weight of his car, the ground clearance may also change.))

Kirillkzn
Reply to a comment by Novaman written a month and a half ago
Well, if you imagine the distance from the bolts to the rim, then the larger radius turns out to be more? .. Even though the% of the tire's tread decreases.

Novaman
The overall diameter of the wheel is the same ...

Kirillkzn
Yes nifiga actually) I at least say based on my personal experience ... Clearance adds and significantly. Now if you take regular car, and put wheels 2 larger on it, after all, it will be like a tank, right?) It will definitely become higher.

Novaman
How did it happen. The diameter of the disc is 18 inches, the thickness of the rubber is an inch. total 20. Diameter 16, thickness 2, total 20. It's another matter if the diameter of the wheel is different. then naturally)

Kirillkzn
Understood nothing)
But logically, using the example of my wheels on Mazda, winter 205/55 16, summer 225/40 18, that is, if 18 inches is 45.72 cm + tread height ((205 * 55) / 100) 9cm, then only 54, 72 cm wheel turns out, in winter 16 inches is 40.64 cm, + tire height 11.275 cm, total 51.915 cm, so my summer wheels in size 18 with tires 2.8 cm higher than winter ones! It turns out that 1.4 cm is added to the clearance.Correct if I'm wrong)

Sonic-sonic
What are you smoking, friend?
I mean, I'm serious, where can I get such crap? I want it too.

Here's a look at the rubber times: oh

But the rubber is two, more: 0

Now insert a disc of a suitable diameter into each. Has the rubber got bigger?)))

PS: you were not mistaken in the calculations, it just has nothing to do with the disc, you need to measure the rubber, it is already = disc diameter + tread height. The error only from the protector itself + - 5mm can be

Kirillkzn
I do not quite understand you, you would at least formulate your thought in one answer, and not in three. and what have you to do with smoking ... I have never smoked at all and nothing for that matter. I answered the question of why the clearance can increase, I substantiated everything, especially since you yourself write that I was not mistaken. and you said the same thing, the diameter of the rubber = the diameter of the disc, I just went with this option, but in the end there is no difference. and the tread error of + -5mm is absolutely insignificant when it comes to centimeters.

Sonic-sonic
Come on, you can create a new science, I don't know how to explain it yet. Well, when you figure it out, do not forget to tell. I smoke it in my own way, but we communicate in the community, so no offense))

Kirillkzn
No, well, we have a dialogue, I do not insist on absolute correctness, I just want to get to the bottom of the truth)

Sonic-sonic
Well, I'm telling you that I understood this issue and painted all the options for you. There + 5mm, here + 5mm - this is how the difference sometimes turns out in cm

Sonic-sonic
wrong. If the disc diameter + tread height is selected, then the total radius can be the same for R16 and R18. If the R18 is larger in the overall radius, then yes, the ride height will increase.
Again, play with the calculator and everything will become clear

Kirillkzn
As the calculator shows, my winter and summer ones are practically one-on-one, the difference in the outer diameter is 5 mm! The difference in ground clearance is indicated in 2.5 mm! Theoretically, you can't notice this in any way! In fact, the difference is much greater, purely for the operation of the car, judging by, and even with the naked eye it is perfectly visible. Now explain how the clearance increases if your wheel + tire is matched almost 1: 1?

Kondaurov
everything says it is verified, you need to read the profile plus the "inch" of the disk. After 16, put 45 and p17 the car became higher, I measured it with a tape measure. The result is on the face

Sonic-sonic
Well, what is the exact parameter of each rubber? Let's count. I explained above what may be an error of 1 cm, but what you say is not realistic from any point of view. No science other than mathematics will help, and with its help it is necessary to count rubber. The distance of the bolts to the central part is the same even if the centering rings are supplied. You can check by taking one car and r16 and r17 wheels. . put the same rubber model on them and calculate its diameter so that it matches. And measure with a ruler to make sure you are wrong.

Sonic-sonic online
the diameter of the rubber takes it all into account. Why count from bolts to rim? It is necessary to count from the very center to the rim, only this is useless, since the size of the tires already takes this into account

Kondaurov
I have a specific example, the difference is not big, but it is.

Sonic-sonic
okay you won. I give up, hard case

The direction of rotation is absent on Bridgestone asymmetrical tires. This means they can be mounted anywhere in the car. They have the appropriate markings.

Direction of the busbars and correct installation

ATTENTION! Found a completely simple way to reduce fuel consumption! Don't believe me? An auto mechanic with 15 years of experience also did not believe until he tried it. And now he saves 35,000 rubles a year on gasoline!

Motorists are increasingly asking how to mount tires correctly and how to determine the correct direction of rotation. If the installation is done correctly, on the contrary, it seems that the structure looks asymmetrical. But that's okay, that's the way it should be.

What should you keep in mind?

The main thing is to look at the driver himself when installing the wheels with the inscription Outside. This applies to all wheels.

In this case, there are several designations for the working surface. Each has its own Bridgestone markings.

1. On the inside: cote interieur, mount this side inside, side facing inwards, inside and so on.
2. For the outside: cote exterieur, mount this side outside, side facing outwards, outside. All designations within one group are equivalent.

Why is it so?

The designers do their best to ensure that the wheels work as a whole on all axles.

To optimize the highly conflicting requirements, asymmetric, non-directional BridgeStone buses have been specially developed. Such wheels must adhere to the road surface with their entire plane. At the same time, it is important that water is also removed from the contact, with maximum efficiency.

To optimize the performance properties, the outer part is specially stiffened. This is especially important for those who often enter high-speed corners. Thanks to high-quality contacts, tread wear in such situations is minimized.

The stability of the effort at the start is ensured by the inner side of the BridgeStone tires. The same goes for braking. Or such an indicator as the effective removal of water from under the wheel.

What about rotation?

Every 50-70 thousand kilometers of run, it is recommended to rearrange asymmetric tires from one axle to another. This is necessary in order to avoid as much as possible uneven wear on the tread. But you need to remember a few more rules.

1. Bridgestone tires can be swapped crosswise if direction is not specified. For example, on the rear-left side, you can put the front right tire. And on the back right is the front left, and so on.
2. If the direction of travel is specified, the tires are swapped on the same side when the front axle changes to the rear.

On some features of tire installation

Fitting asymmetric Bridgestone tires does not require any special skill or skill. It is enough to remember a simple set of rules. The inscriptions on the inner and outer sides have already been mentioned. Then, after installation, these labels should no longer be visible. Only an indication of the outside should be seen.

But with directional tires, things are a little more complicated. They must be positioned so that the rotation of the wheel coincides with the direction of the arrow on the sidewall when the vehicle is moving forward. Only on the side indicated on the tire are wheels with left and right orientation. When considering the side, you need to rely on forward movement.

Symmetrical tires have no direction of rotation or sides. Their installation is possible in any of the available positions.

The performance of the vehicle while driving is severely degraded if directional, asymmetric tires are installed incorrectly. The wheels themselves are not working properly. Consequently, the characteristics are not fully disclosed, even if they are correct.

About mounting tires and wheels

The process itself should not cause any problems. Better to look in the instruction manual in advance. vehicle... It provides specific advice, recommendations for the procedure.

1. It all starts with removing old wheels and tires. Why you need to unscrew the nuts. But you do not need to get rid of them to the end, it is enough to weaken them a little. It is safer to use hand tools for such work. Other options should only be used if you have special skills. If they are not there, it is not recommended to conduct experiments.
2. A jack is useful to raise the vehicle. The main thing is that the working surface is flat. Now the nuts can be unscrewed, completely get rid of the wheels.
3. In order not to get confused later, it is recommended to distribute the buses into several groups from the very beginning. It is better to put them in the same place as the old wheels. It is important to consider the direction of rotation, and pay attention to this particular factor. The same goes for the sides of the tires, the pattern on their surface.

Additional checks require rubber nuts. If there are even the slightest defects on them, they are corrected even before the final installation of the wheels. The store sells special kits for restoring threads on such tools. They will become indispensable helpers.

1. Drums with brake discs must be free of rust, any traces of contamination.
2. It is also necessary to check how the wheels are connected to the hubs. Tire runout is a consequence of the deviation of the center of the disc, even when it is small. Additional steering wheel vibration will appear. Otherwise the tire anchorage will be in jeopardy.
3. To treat bolts against corrosion, you need to take wax spray, other substances suitable for such work.
4. They proceed to the installation of the wheel if there were no problems at the previous stages. First, the bolts are baited, then they are slightly tightened. After that, the car is released. The jack is retracted and the nuts are tightened to the very end.
5. Then it's time to do a post-installation check. The main thing is not to touch such parts as the inner side of the rim and the outer edge of the disc. To check it is enough to run your hand over each of the wheels. The tire pressure indicator requires a separate check.

Radial tires

This type of product is relevant for both conventional passenger vehicles and trucks. The name reflects the structure of the framework. The fibers in such tires are located at an angle to the direction of travel, 90 degrees. The marking will provide the information you need.

Radially, the fibers are located on the sidewalls - they look like rays extending outward from the center. Due to this, even in the lateral direction, the shape of the tire remains stable. Steel cord is used to ensure that the transmission of force is optimal, including in the longitudinal direction.

About bias tires

And in this type, the frame is created from special fibers. They are also located at a certain angle to the direction of travel. The fibers form a mesh by folding on top of each other.

Thanks to this design, it became possible to create tires with a round shape. The diagonal type of product is not equipped with steel cord. Therefore, it is not suitable for joint operation with trucks... They are easy to recognize, the marking is applied accordingly.

These types of tires are used where contact with the coating must be ensured not only at the bottom, but also on the sides. This requirement is important for agricultural machinery, motorcycles.

About tire wear indicators

In the grooves, between the tread, there are small protrusions, which become indicators of wear. The tire definitely needs to be replaced if the height of the ridges and the dimensions of the tread are equal to each other. These markings on the tires make maintenance easier.

The letter abbreviation TWI is applied to the lateral side in the same place as the wear indicators. This will make the location easier to find.

It is advisable to install car tires of the same size on one car. If possible, the manufacturer and model should also be the same. Some tread patterns may be similar to each other, but each tire model has its own unique characteristics that are unique to it.

The grip properties will differ even if tires with a very similar but still different pattern are installed on different axles of the vehicle.

Regardless of what the tires are for: for passenger car or is it tires for off-road vehicles - they are divided into several main types:

Asymmetric tires- tires with different tread patterns on the outside and inside of the treadmill. Indicated by the following inscriptions on the side of the wheel: “Outside”, “Inside”, “Facing Out”, “Side Facing Inwards”, etc.

Symmetrical tires- These tires have a symmetrical tread, cord and sidewall construction. They can be installed on the vehicle in any position.

Directional tires- car tires with a strictly directed tread pattern, the direction of rotation of such wheels is indicated by an arrow on the sidewall of the wheel. They are marked with the inscription "Rotation" and an arrow of the direction of rotation.

"Left" and "Right" tires are terms denoting wheels, during the installation of which it is necessary to strictly observe the conditions of their installation on the car: "right" only on the right, "left" only on the left.
You can recognize them by the “Right” or “Left” markings on the sidewall of the wheel.
If there are no such inscriptions on the sidewall of the tire, then the tires of this model are not subdivided into "Left" and "Right", regardless of whether they have a directional or asymmetric tread pattern.

These concepts are not mutually exclusive, asymmetric and directional rubber occurs at the same time. Several years ago the company produced asymmetric "Left" and "Right" tires.
But at the moment, asymmetric tires with a given direction of rotation are not produced, since "Left" and "Right" tires do not give special advantages in wheel characteristics, and at the same time, such a solution greatly increases the cost of production and creates additional problems in warehouses and shops.

Features of the tire design.

Nowadays asymmetric tires - both summer and winter tires - are gaining more and more popularity among motorists. The inner part of the asymmetric tire is made softer than the outer one, this is due to the fact that the load during cornering is mainly borne by the outer part of the wheel. This significantly improved the car's handling. Also, in general, an increase in the area of ​​the contact patch of the tire with the road surface had a positive effect on the directional stability of the vehicle. In addition, due to the fact that the tread blocks on the outside of an asymmetric tire are larger than on the inside, improved drainage when driving on a wet road surface, which has a positive effect on the tendency to reduce the likelihood of aquaplaning.

Directional tires with the best indicators of drainage from the contact patch of the wheel with the road, in terms of directional stability and controllability, are still inferior to asymmetric ones. But on the other hand, the risk of avaplaning in directional tires is much less due to the fact that the active drainage of water from the contact patch is carried out in both directions.

The appearance on the market of "left" and "right" tires was also due to the desire of the manufacturer to make driving the vehicle the safest, but, unfortunately, it turned out to be somewhat hasty. We can say that the constructors automotive rubber a little overdone and did not foresee some factors. First, the production of such wheels significantly increased the manufacturing cost, which was reflected in the retail price; secondly, there was confusion in the suppliers' warehouses; thirdly, the consumer did not understand which spare wheel to carry with him: left or right, because it is not known from which side a puncture of the wheel will occur. Due to these factors, at present, tire manufacturers do not produce strictly "left" or "right" tires.

Features of the installation of tires.

Fitting asymmetric tires

Installation rules asymmetric tires intuitive and simple enough.
When installing a wheel with an asymmetric tire on a car, its outer part must be labeled Outside (or similar from different manufacturers: External, This side facing outwards, Side facing outwards, etc.), at the same time, the inscription on the inner part of the wheel Inside ( it is the same: Side facing inwards, This side facing inwards) remains invisible to you, because is directed this side towards the vehicle.

Simply put, with the correct installation of asymmetric wheels, when walking around the car, you should only see Outside on the tires.

Installation of directional tires

Directional tires is set so that when the vehicle is moving forward, the direction of rotation of the wheel coincides with the direction of the arrow on the sidewall next to the Rotation inscription.

"Left" and "right" tires, as mentioned above, are installed, respectively, strictly on the sides of the car, which corresponds to the inscription on the tread Right (right) or Left (left) (in the direction of the car forward).

Installing symmetrical buses

Symmetrical tires have neither outer sides nor a given direction of rotation and therefore can be installed in any position.

Note also that improper installation of asymmetric or directional tires on a car degrades the performance of the vehicle during its operation.
Incorrect "work" of tires in this case negates all the efforts of designers aimed at giving the wheels improved characteristics. When driving a car with improperly installed wheels (if there are simply no other options), it is necessary to observe increased vigilance on the road and move at a speed of no more than 80 km / h.

We hope that our tips will help you in checking the installation work.
