Someone is actively fond of fishing and hunting, someone spends their leisure time overcoming obstacles on the road. But they all think about increasing the cross-country ability of their SUV. One of the questions of interest: how to remake a UAZ on low-pressure wheels, to get an all-terrain vehicle off-road.
The products of the Ulyanovsk Automobile Plant have long proven themselves on the positive side. These are off-road vehicles, unpretentious in terms of fuel quality, long service life and an affordable price for new models. The most popular models: UAZ-452 "Loaf", "Hunter", "Patriot".
"Pros" of installing low pressure tires
Of course, it is important to use it to be sure of the result of the effort. One of the factors for improved flotation is low pressure tires. Many motorists set them up for their vehicle to perform cross-country tasks:
- Improvement of off-road vehicle cross-country ability;
- The area of adhesion to the road surface is 27% more than "civilian" analogues;
- Possibility of additional installation of lugs to give the car a squat;
- Low pressure tires are less harmful to the environment. In terms of preserving the environment, there is no alternative;
- Increase in clearance several times.
Low pressure tires: disadvantages
- The design of the UAZ is undergoing significant changes in the front, rear suspension... That automatically entails significant financial costs;
- The center of gravity is 17% higher than the stock counterpart. The coefficient of exchange rate stability is reduced, there are frequent cases of the car overturning on its side;
- Frequent use on asphalt pavement leads to rapid wear of the rubber. Therefore, assess the likely geographic range of the SUV before purchasing (installing) low pressure tires;
- Be careful with speed as well. Tires don't like high modes, they are designed to overcome off-road, not asphalt;
- The load on all transmission units is automatically increased. Consider this when developing a schedule for a technical inspection.
Conversion of UAZ to low pressure wheels
- Check constituent elements pendants, rate them technical condition, the ability to withstand increased load;
- When choosing tires, check temperature conditions for which they are designed. You will need two sets for summer and winter. There is no all-season low pressure;
- Unlike civilian models, low pressure does not have internal pressure standards. Each case is individual;
- Tread size: deep does not mean better. Remember that every millimeter of depth significantly increases the load on the drivetrain and undercarriage off-road vehicle. Select based on the geographic environment of the machine.
"UAZ loaf" model remake
How to make low pressure wheels?
- We are preparing the basis from which we will build the all-terrain vehicle. Remember what older model, the more changes need to be made;
- We prepare the rear axle, differentials, suspension elements. Connect with rear axle;
- We screw the wheels to the suspension. Take from the Urals, KAMAZ as standard hubs;
- We select power unit... If you leave the former, it will be difficult for him to cope with some tasks on rough terrain;
- Cooling system, clutch, brake circuit are completely recyclable;
- We form optics, lighting, power supply system;
- The final stage: installation, performance check, tightening, fine tuning of the unit.
The installation of low-pressure tires includes a whole range of works on the modernization of technical equipment. Without the skills and experience in servicing off-road vehicles, the desired result is unlikely to be achieved. To reduce the risks to zero, hire service station specialists for a successful upgrade of the UAZ SUV. Otherwise, the suspension elements may not withstand the load, deform, and even break the fastening eyes.
In any case, high-quality wheels are a guarantee of trouble-free off-road driving. Wide from the best manufacturers on the Bezdor4x4 website. Read also the article on our blog.
In recent years, among the owners of SUVs and all-terrain vehicles, the use of low-pressure wide-profile tires has been developing especially dynamically. These tires are mass-produced at modern tire factories, such as the AVTOROS brand, in compliance with high quality standards and with high performance characteristics... This type of tire assumes a very low pressure inside the wheel with an adjustment, due to this, the contact area of the tires with the ground increases and the vehicle's permeability is increased. Among off-road enthusiasts, the term "peeling" is also used - this is a used tire from a KRAZ truck, from which several layers are "peeled off". As a rule, such a tire is installed when there is no opportunity to purchase new ones. quality tires low pressure.
Specifications
In order to buy off-road tires for UAZ, Niva, GAZ 66, GAZ 33081, LuAZ, KamAZ-all-terrain vehicle and other off-road vehicles, you need to know them specifications... These include the dimensions of the required wheels in inches, consisting of three numbers:
- tire diameter;
- tire width;
- seat diameter of the disc.
Advantages
Low pressure all-terrain rubber has several advantages over conventional tires:
- the cross-country ability of cars, all-terrain vehicles, off-road vehicles increases by 20%;
- compaction of soil is excluded when using such tires on agricultural transport;
- lightweight tires with large tread improve traction;
- tires ultra low pressure significantly increase the buoyancy of vehicles from a car to a swamp vehicle
Specificity of use
It must be remembered that in addition to the numerous advantages, there are also some specific features of the use of such tires. Therefore, car owners who intend to buy new low-pressure tires or use used strips for their SUVs and ATVs need to remember the following nuances:
- low pressure tires reduce the speed of the vehicle;
- tires or rims on UAZ and Niva when moving on concrete and asphalt are subject to severe wear;
- acceleration and deceleration of the vehicle must be extremely smooth;
- you should turn smoothly and along the maximum trajectory, since the sidewall of such tires is prone to transformation under loads.

The legendary car is again at the peak of popularity
In our time, all-terrain vehicles are gaining special popularity. Such a mode of transport as an all-terrain vehicle based on a UAZ vehicle can be created with my own hands... It is a cheap and convenient form of transport. Most car owners who have such a car in their garage can be proud of it, because they created this miracle with their own hands. At this stage, there are already many exhibitions and forums for craftsmen have already been created, who share their experience with beginners.
Such all-terrain vehicles are most often created on the basis of UAZ, from old models to newer ones, the main thing is that they are in working order. UAZ 469 vehicles are being redesigned to be equipped with low pressure tires. In this case, the car turns into an all-terrain vehicle capable of driving through the most impassable places.
Rubber for UAZ is quite expensive, so many are beginning to think about how to use funds as economically as possible. And everything is quite simple: make your own low-pressure tires. But in order to "re-shoe" the car, equipping it with this type of tires, you will have to redo various suspension elements and body parts, re-equip bridges. All this is due to the fact that enormous loads are created on various systems due to the frequent displacement of the center of gravity in the car.
The bridges installed on the UAZ 469 model can fail due to constant off-road driving, and the clutch system will quickly fail. Therefore, the conversion of a car into an all-terrain vehicle on low-pressure UAZ Patriot tires for driving in difficult-to-pass places must be approached in detail and all issues must be resolved in a complex.
- the cross-country ability of the car increases;
- the pressure in the UAZ tires allows you to create better grip on any moving ground by increasing the grip plane;
- lugs specially provided in the design of the low-pressure tire make the UAZ 469 more responsive;
- it becomes possible to use a car in agricultural production, since, due to the low pressure in the tires, the UAZ has a lesser effect on the soil and does not crush the plants when driving through the fields, leaving them viable;
- due to the greater width, the ground clearance is increased, which ensures better vehicle stability on the road.
This type of rubber is intended for off-road use only.
At the same time, low-pressure tires on UAZ have a number of disadvantages:
- to install them, you will have to make quite a few alterations in the car, requiring large financial investments;
- the car becomes higher, as a result of which the center of gravity shifts, which can lead to a rollover of the car;
- due to the greater softness of the tires, they wear out greatly during prolonged driving on asphalt;
- tires are not suitable for high-speed driving, but only for off-road driving, which is a limitation in the use of the car;
- due to the greater vibration and displacement of the center of gravity of the UAZ 469 when driving in off-road mode, the load on the transmission and other components increases. But the most critical increase in load is felt when traveling on ground, requiring tires with a large tread height.
The choice of low-pressure tires for the UAZ 469 is influenced by the temperature indicators of the region in which the car will be used. To operate a car on this type of tires both in winter and in summer, you must have two sets of rubber. Although in this case there is no clear division into summer and winter tires... It is important that the rubber does not increase its rigidity at sub-zero temperatures. Excessive rigidity reduces permeability, since the ability of tires to plastic is a guarantee of off-road driving. If it is impossible to deform in a rigid low-pressure tire, the contact spot on the ground or snow will decrease on the UAZ.
There are several UAZ tread patterns on low pressure tires. Each of them is designed for a certain type of soil on which it is planned to move on such wheels. Moreover, a tire with a deeper tread is not always better. The wheels of the UAZ 469 with a large tread interact more efficiently with the ground, providing good traction, but at the same time creating an unnecessary load on the transmission. Therefore, it is very important that the pressure in the tires of the UAZ has a certain indicator.
Soils are different in consistency, which must also be taken into account when choosing a low-pressure tire for UAZ 469, UAZ Patriot.
Instructions for making tires
Homemade low pressure tires
For the manufacture of low-pressure tires at UAZ, it is necessary to find the source material. You can use cameras for helicopters and aircraft: they meet quality requirements and will last a long time. The high cost and scarcity of this product are the impetus for finding other, more affordable options. One of the best solutions in this case may be to use tires. trucks... Of course, their alteration will require considerable effort, both physical and temporary, but this will reduce the cost of re-equipping vehicles based on the UAZ 469.
Cooking necessary tool(knives, scraper, sharpener, hammer, awl, nippers) and determine the size of the required tire. To remove layers from the tire, we use a scraper - a fixed winch with an electric drive and a start button located at the workplace. Now we need to remove the outer bundle of wire cord. To do this work, we will cut through a window, thanks to which we will bite one of the turns with pliers, wind the wire on the pliers and pull it out. It is advisable to do these manipulations along the entire length of the wires. We cut through the entire sidewall from the cord to the tread with a distance of 7-10 cm and go deeper to the first layers of the cord.
We undermine the canine with nippers, this should be done only along its edges, and strictly clockwise, because the top layer of the cord will appear on the right side.
Graphic markings are the basis for tread formation. The pattern in such tires is determined by the functional purpose. Herringbone is one of the simplest and most common options. Having finished the drawing, we cut through its contours. The tread section must have the shape of a regular trapezoid. Having finished the work, we proceed to the peeling. The longest part in this process is preparation, but it is this that affects the speed and quality of work. It is necessary to avoid undercutting the tread canine, since the slightest mistake threatens us with irreparable consequences. After finishing the last canine, the cord layer on the right will also disappear.
It is necessary to pick up the canine with pliers and slowly, increasing the tension of the winch cable, hook the side edges. It is relatively easy to do this work, but you need to work with concentration and attention, focusing your attention on the smallest details. Otherwise, your low pressure tires will start to flake.
When selecting low-pressure tires for UAZ, one should be guided by many indicators, including environmental factors and vehicle applications. Special care should be taken when choosing an off-road tire tread.
Don't forget about the disks. They can be made using standard analogs, having previously adjusted them to the desired size and proportions. You can attach discs and cameras with belts or a fire hose.
Modification domestic cars does not stand still. You can improve the car both from the inside and from the outside. A striking example of this is UAZ on low-pressure tires. They can be ordered from specialized workshops or made by hand. A similar design is successfully used on heavy soils, where standard wheels difficult to drive.
What is a low pressure tire?
The element in question is an enlarged wheel that resembles a pillow, inside of which there is low pressure. This design creates excellent grip on any type of ground and allows you to drive on almost any off-road.
Has the following features:
- A significant area of contact with the ground makes it possible to overcome obstacles that a conventional wheel cannot do.
- Low tire pressure avoids significant stress on the soil, which is actively used in agricultural work and geology.
- A lot of experience is required to drive vehicles with such a modification. Wheels are not designed for high speed, especially on asphalt and other stone surfaces where they wear out quickly.
UAZ on low pressure tires: modification features
Before using vehicle on low pressure tires, make sure they are suitable for the climate in the region. Although there is no definite division into winter and summer types for this type of tires, it should be borne in mind that greater rigidity reduces the contact of the wheel with the road stain.
It will not be possible to simply simulate the structure in question. Substantial revision of the body, transmission and axles will be required. Although the increase ground clearance when using such tires, it provides better stability of the car and provides a number of other advantages, which were discussed above, there are certain disadvantages. First, tires are subject to heavy wear on hard surfaces. Secondly, the load on the transmission unit and the chassis of the car increases. Finally, low-pressure tires for UAZ, the price of which is incomparably higher than standard ones, require special storage and operation conditions.
Tire pressure
It is necessary to remember about correct balancing when This moment is one of the most important factors that affects the correct operation of the machine. Special designs should be installed to help increase performance and reduce vehicle wear.
What to do after the updated bus is installed? Low pressure discs on UAZ must be protected with beadlocks, which are mechanical rings. They ensure the stability of the wheel in the event of additional lateral loads. In fact, it is a rigid fixation of the tires to the rim board.
Pros of bedlocks:
- protect the wheel from disassembling:
- elementary installed and maintained.
The disadvantages of this element include the impossibility of perfectly accurate balancing and a slight increase in the mass of the car. In addition, UAZ on low-pressure tires will feel more confident if equipped with a tyrlock, which ensures reliable fixation of the tire along the edges of the rim.
- The same tires must be fitted to all wheels.
- It is necessary to observe the optimum pressure in them.
- Periodically, you need to check the wheels for air passage using a soap solution.
- To ensure uniform wear, it is advisable to swap the front tires with the rear ones after every 10-15 thousand kilometers.
- After running in new rubber rebalance.
- Care must be taken to ensure that the characteristics of the tires are consistent with seasonal variations.
Do-it-yourself low-pressure tires for UAZ
To make the structure in question with your own hands, you need to select the appropriate material. "Shoes" from airplanes or helicopters are ideal. However, this is a rather expensive option. In most cases, rubber from tractors or trucks can be used. From the tool you will need a sharpener, a knife, a hammer, wire cutters, an awl.
Then the following manipulations are done in stages:
- A new tread pattern is selected and cut at the owner's discretion. The most popular is the “herringbone” style.
- An incision is made around the circumference of the wheel to be machined so that it is possible to remove the reinforcing wire.
- On the inner base, holes are made in the form of small rectangles, through which the wire will be removed using a winch device.
- It is necessary to focus on the conceived pattern of the picture, fishing out an unnecessary layer of reinforcement with the help of a winch and pliers. Taking into account the previously applied pattern, the drawn part is corrected with a knife.
Main process
While mastering how to put low-pressure tires on a UAZ with your own hands, it is necessary to gradually adhere to the following operations:
- Rubber is removed from the sidewalls and tread in layers.
- The prepared surface is cleaned with sandpaper and straightened with a hammer.
- A new frame is assembled using welding, metal disc and plate elements.
- Weld seams are ground.
It is quite possible to make wheels for new tires on your own from scrap materials. An aluminum basin is suitable for this. The parts can be secured using the remnants of a conveyor belt or a fire hose. Then the camera is put on the frame, pumped up and checked for air leaks and internal pressure. It remains only to install a new design and go to conquer any tracks that are too tough for standard wheels.
Features of operation
UAZ on self-made low-pressure tires can overcome various obstacles. This is due to the contact with the ground of a large area of the wheels. Such rubber envelops almost any surface, taking the form of an object on the way. Experts say that an SUV on low-pressure tires has an efficiency that is 20% higher than that of cars with standard wheels.
Disproportionately big tires avoid high pressure on land, which is important in agriculture and farmland. Operating a machine equipped with the structure in question requires certain skills. On such wheels, it is necessary to very smoothly enter the turns, maintain a moderate speed and try not to operate the car for a long time on asphalt and concrete roads. This will avoid premature wear of the non-standard rubber.
Modifications
The UAZ car has a wide range of modifications. This machine has been used, and in some places continues to be used, in the following industries:
- Medicine.
- Hunting.
- Agriculture.
- Food and light industry.
Affordable price, easy operation and design features made it one of the most popular means of transportation in the countryside. Modernization of the car allows you to expand its capabilities. For example, UAZ "loaf" on low-pressure tires makes it possible to move in swampy areas and on any kind of soil.
It is worth noting that with some modifications to the body and chassis, low-pressure tires can actually be installed on all UAZs, including the classic and Patriot.
Financial side
Low-pressure tires for UAZ, the price of which ranges from 50 to 100 thousand rubles apiece, is more profitable to do it yourself. Considering the pros and cons, this procedure is no less effective and much more profitable. Judging by the reviews of the owners, this modification is extremely suitable for any off-road. However, the use of such rubber on standard roads is disadvantageous. On hard surfaces, the low pressure structure will wear out quickly. Also, these cars are not designed for high speed.
If we compare the optimal pressure in standard UAZ wheels with a similar indicator that UAZ has on low-pressure tires, we can understand in what conditions they should be used.
Conclusion
Having considered all the advantages and disadvantages of low pressure tires, the following can be noted:
- They are ideal for off-road use.
- Such wheels should not be used on asphalt and other smooth surfaces, due to their susceptibility to significant wear.
- The ability to make a product with your own hand will save a lot of finances.
Before deciding on the installation of high-pressure tires, you should compare all the pros and cons of the modification, taking into account the refinement of the body, chassis and transmission of the car. The modernized "UAZ" will perfectly cope with the assigned duties in the field of agriculture, geology, and the study of areas where there are no standard roads.
Its use on hard surfaces is impractical and can lead to excessive waste of money and frequent replacement rubber. Another important nuance is compliance installed tires climatic conditions of the region.
