Low pressure tires. Low pressure tires for uaz uazik with low pressure wheels bolotnik

Modification of 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 in specialized workshops or made by hand. This design is successfully used on heavy soils where it is difficult to drive on standard wheels.

What is a low pressure tire?

The element in question is an enlarged wheel that resembles a cushion with low pressure inside. This design creates excellent grip on any type of ground and allows you to drive on almost any off-road.

Has the following features:

1. A significant area of \u200b\u200bcontact with the ground makes it possible to overcome obstacles that a conventional wheel cannot do.
2. Low tire pressure avoids a significant load on the soil, which is actively used in agricultural work and geology.
3. 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 the vehicle with 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 must be borne in mind that greater rigidity reduces the contact of the wheel with the road stain.

It will not work simply to simulate the structure in question. Substantial revision of the body, transmission and axles will be required. Although the increase in ground clearance when using such tires provides better vehicle stability and provides a number of other advantages that 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 provide wheel stability 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.

1. The same tires must be fitted to all wheels.
2. It is necessary to observe the optimal pressure in them.
3. Periodically, you need to check the wheels for air passage using a soap solution.
4. To ensure even wear, it is advisable to swap the front tires with the rear ones after every 10-15 thousand kilometers.
5. Rebalance after breaking in new rubber.
6. Care must be taken to ensure that the characteristics of the tires are consistent with seasonal changes.

Low pressure tires for UAZ do it yourself

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 UAZ with your own hands, you must gradually adhere to the following operations:

1. Rubber is removed from the sidewalls and tread in layers.
2. The prepared surface is cleaned with sandpaper and straightened with a hammer.
3. A new frame is assembled using welding, metal disc and plate elements.
4. Weld seams are ground.

It is quite possible to make wheels for new tires yourself from scrap materials. An aluminum basin is suitable for this. Fixing the parts is available with 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 set off to conquer any tracks that are too tough for standard wheels.

Features of operation

UAZ on homemade low-pressure tires can overcome various obstacles. This is due to the contact with the ground of a large area of \u200b\u200bthe 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.

The disproportionately large tires avoid the high ground pressure that 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, ease of use and design features have made this car one of the most popular means of transportation in rural areas. Modernization of the car allows you to expand its capabilities. For example, UAZ "loaf" on low-pressure tires makes it possible to move around in swampy areas and on any kind of soil.

It should be noted 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 the same 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 result in excessive waste of money and frequent rubber changes. Another important nuance is the compliance of the installed tires with the climatic conditions of the region.

Many car enthusiasts who are fond of fishing or hunting, as well as those who live in rural areas, often think about how to increase the cross-country ability of their car. Many people are interested in whether it is possible to turn an ordinary car into a cross-country vehicle with their own hands.

UAZ cars are a very famous model of domestic production, which was produced specifically for conditions requiring increased cross-country ability.

Patriot on low pressure tires

This is the UAZ-452, the so-called loaf - one of the first models with increased cross-country ability. The “Loaf” has been used for over 50 years in heavy traffic conditions, especially in villages. These are the newer models "Hunter" and "Patriot", released after 2000.

As you know, one of the factors that significantly increases the cross-country ability of a car are.

Many skilled car enthusiasts manage to make a UAZ on low-pressure tires with their own hands, turning it into an excellent all-terrain vehicle that is not afraid of either muddy roads or snow blockages.

Advantages of installing low-pressure tires on UAZ

Let's consider what advantages we get by installing low-pressure tires on the UAZ:

• the passability of the machine is significantly improved;
• tires of this type increase the traction patch;
• in such cases, special lugs can be installed, which make the car more squat;
• the use of this type of rubber reduces the negative impact on the soil, which is very important in terms of environmental performance;
• there is an increase in ground clearance, which inevitably occurs when tires with low pressure are installed.

Disadvantages of installing low pressure tires on UAZ

However, this kind of tuning has its drawbacks. These could be the following factors:

• to install such wheels, you will need to make a number of serious transformations in the design of the car. It is quite labor intensive and entails significant financial costs;
• a higher location of the vehicle's center of gravity negatively affects its stability;
• when it comes to driving on an asphalt surface, you must take into account that it wears out low pressure tires a lot. Therefore, all-terrain vehicles of this kind are not recommended for frequent and long-term movement on asphalt surfaces;

Disadvantages of low pressure tires for UAZ

• you also have to be careful with speed. Low pressure tires are not designed for high-speed movement - here the main task is to drive on off-road surfaces and overcome obstacles;
• take into account the increased load on the transmission units. When driving on terrains that require high profile treads, critical load values \u200b\u200bcan occur.

Things to consider when redesigning a car

If you decide to convert your UAZ into an all-terrain vehicle by installing wheels with low-pressure tires, you will have to take into account some factors:

• be prepared for the fact that you have to make a number of major changes to the transmission, axles and body elements of your car. This is especially important when it comes to redesigning cars such as the "loaf". UAZ "Patriot" on low-pressure tires will require much less design changes than a "loaf". This is due to the fact that at the time when old models were produced, modern technologies and materials were not yet used;

The choice of tires for UAZ

• when choosing a rubber, it is very important to take into account the temperatures in which they are planned to be used. For summer and winter use of the vehicle, you will need at least two sets of rubber;

• rubber for low pressure does not have a clear division into summer and winter options. For winter, such species are used that do not become hard at negative temperatures. This can negatively affect the passability of the vehicle;
• when choosing a tread pattern, remember that “deeper” does not always mean “better”. Increasing the depth of the pattern puts more stress on the drivetrain - consider the ground you plan to navigate and choose the best pattern depth.

All work on the manufacture of an all-terrain vehicle based on a UAZ vehicle can be divided into several conventional stages. Let's analyze them in turn:

1. Choosing a base. If there is no UAZ in the garage suitable for turning into an all-terrain vehicle, we will have to find the right base. Remember that the older the model, the more changes will need to be made.
2. We make the rear axle and suspension. It is better to use an independent construction here. Its production will entail an increase in labor costs, but this will increase the vehicle's cross-country ability. The suspension is connected to the rear axle with a special strut and steering sleeve.
3. We attach the wheels to the suspension. Metal hubs are needed here. We can use cameras from trucks like the Ural.
4. We select an engine, carry out installation and design a cooling system.
5. After installing the engine, we mount the exhaust and brake systems and the clutch. We install the headlights and connect all the commutation.
6. We carry out all the necessary tests of the received all-terrain vehicle, eliminate shortcomings and defects. After making all the corrections and positive test results, we can consider the work completed - our all-terrain vehicle is ready to overcome difficulties.

Conclusion

Conversion of a UAZ car for low pressure tires - a whole range of works to improve the design.

For any all-terrain vehicle decisive condition for excellent flotation is to use the correct tires.

But the cost of a suitable kit is considerable, because it is often produced either in small quantities or by special order.

But to make low pressure tires quite real on my own... This work is laborious and requires patience and attention. The finished product has a characteristic name - skins.

Ripped tires (they are also low-pressure tires) are huge tires of a tractor, truck or helicopter "stripped" from excess rubber.

Due to the large area of \u200b\u200bthese wheels and their low pressure on the surface equipped with them an ordinary car becomes a real SUV.

With the rags, Niva and UAZ can overcome a wide variety of obstacles - fields, deserts, rocky and swampy soil.

Low-pressure wheels are difficult to do without hunters and simply amateurs to ride on difficult terrain.

Making these tires yourself is not a problem. For this, the most common tools like a knife or a winch... You also need a little skill.

Before you start creating low pressure tires, you need to clearly understand what exactly are they needed for, that is, in what conditions, where exactly they will be operated.

• primarily for driving on muddy, bumpy roads and rural roads - then you need to use a self-cleaning tread;
• if, on the rims, we will overcome swamps, it will be necessary to lower the tread grooves a little so that the grip is as good as possible;
• on and on sands it is better to ride on tires on which the elements of the tread pattern are as close as possible to each other.

Think about the above in advance.

Low Pressure Tire Making Process

To make tires with low pressure for UAZ, Karakat or Niva, you need to create the tire itself, as well as a strong metal base to attach it to.

For self-creation of skins you will need:

1. Main material - old tires for trucks such as Gaza-66, Kraza 255 (VI-3 tires), ZILa 131. Tires from helicopters, tractors and small planes are also perfect. If your tires have a chewed-up interior, don't use them. A hole can form in such rubber after the top layer is removed. As a result, they will simply have to be thrown away.
2. Shiloh, knife (construction), a set of blades and a sharpener for their editing. When in contact with durable cargo tires, the blades quickly become dull and unusable, so one cannot do it.
3. Special template made of thin steel sheet or thicker cardboard, as well as a chalk or marker for stroking the template.
4. Clamps (as strong as possible). The ones with which the straighteners clamp the bodies of crumpled vehicles when trying to level them are best suited. For stripping tires a standard clamp will work too, but maximum accuracy is required. You can wield the workflow with conventional wire cutters.
5. Winch (automatic or manual) and a cable to tighten the part of the tread to be cut. You can also tighten it with a manual gearbox.

You may also need a hammer (for straightening).

Large tires will need to be freed from excess rubber on the tread and sidewalls to make the rims. It is also necessary remove landing cores and cord base (inner protective layer of the tire).

• tire thoroughly we clear all the dirt, and then dry;
• using a template, marker or chalk around the entire circumference of the wheel create a tread pattern (the way it will become after some of the unnecessary rubber is removed).

1. We make an incision along the inner perimeter of the tire so that get rid of the wire... It is better to make an incision with a construction knife. It is convenient in that you can set the length of the blade.
2. In the area of \u200b\u200bthe notch with a marker, mark the rectangles and start them to cut.
3. Through the holes in the tire we can see the wire, which we will get rid of.
4. We fix the tire with an iron rod so that it does not move, and hook on the wire, remove the winch from the tire. You can also remove it with a screwdriver, but this will take a lot of effort.

Now we begin to strip the tire:

• around the circumference of the tread circle we have drawn making cuts, we go a little into the rubberized base of the cord;
• using mites formed fix the hole;
• rubber that has peeled off with a winch pull and rip.

To make things go easier and faster, we cut it with a knife.

• gradually rip off unnecessary layers rubber and cord from the tread surface and sides until one carcass remains;
• we clean the surface with sandpaper (if necessary, flatten with a hammer).

The camera for the future wheel is ready.

1. Create a new tire cage... We weld rims with plates. Low pressure rims can also be created by yourself. For this, the most ordinary aluminum basin and a fire hose (for fastening) are suitable.
2. Grinding the frame.
3. We put on camera-bump on the frame.

We swing the tire and can install it on our car.

Pros and cons

The cheats have a lot advantages over purchased wheels:

1. Price. The off-road wheels are very expensive, which cannot be said about the rims.
2. Such wheels adhere perfectly to almost any surface, which significantly reduces the risk of accidents.
3. Rummings weigh relatively little. An "unpumped" light car engine will cope with their cranking.
4. Low surface pressure due to large tire area. With roughness, swampy terrain, quicksand and deep snow become quite passable obstacles. The tire pressure on the surface is adjustable. They just need to be pumped up or lowered a little.
5. Tires with low pressure do not harm the surface soil layers in any way, so you can safely drive an all-terrain vehicle with rims on plowed fields, use it as a tractor in agriculture.

Are not devoid of ruff and some disadvantages:

1. On hard asphalt and concrete surfaces on rims, you should try to drive less. Otherwise their will have to change very soon.
2. A car on such wheels is not very stable. It is better not to make sharp turns on it, and you cannot drive quickly at all.
3. Wheels wear out much faster ordinary.
4. Ruffling is a big burden. Transmission and suspension parts with such wheels will have to be replaced and repaired more often.
5. Low pressure tires are very flexible. This increases their permeability. But due to the increased elongation of the skin pierced more often conventional tires.
6. Car will have to reissue - "upgrade" to the status of an all-terrain vehicle.

Conclusion

Ruffles are a very inexpensive replacement for all-terrain tires. Making them is not difficult at all.

They will turn an ordinary UAZ or Niva into a real all-terrain vehicle and SUV. You can drive such a car everywhere.

Another idea for technology is homemade caterpillars, which you can read about.

And if there are tractor tires left, you can make a lot of others from them.

In contact with

Not so long ago, it released new low-pressure tires M-TRIM, dimension 450-45x18 LT.
Those. the diameter of this tire is 900mm. Avtoros also produces wheels for this tire with a UAZ hub.
So they can be installed on the UAZ!

One of the first projects to install low-pressure tires M-TRIM at the UAZ Patriot was the BALU project led by Viktor Sverzhevsky.

The car on such wide "legs" resembles a bear, which is why the name BALU appeared

To fit large and wide wheels, the arches had to be trimmed.

Lift suspension.

And install the wheels themselves through the hub spacers. :(

This made it possible to install low-pressure tires on the UAZ Patriot at minimal cost.

It remains only to improve the appearance: to install the wheel arch extensions, bumpers. And also to test the design in practice.

Primary tests took place at the Avtoros test site

There are puddles, a bit boggy sections of the road. The very thing you need for a pneumatic car.

I even managed to sit at the helm of the all-terrain vehicle.

Interesting sensations: rides softly, as if a cat is sneaking. But the unbalanced torque is annoying.
The engine is standard, gasoline ZMZ-409, five-stage gearbox, RCP with a decrease of 1.9. All this leads to the fact that the wheel rpm is too high, even with a decrease. To drive through the swamp "vnatyag" has to "torment" the clutch.
It is necessary to reduce the speed either by installing the KIT in the distribution box, or using another Main Pair (GP).

main gear (or Home Couple) - the gear mechanism of the transmission of cars and other self-propelled machines, which serves to transfer and increase the torque from the propeller shaft to the drive wheels, and, consequently, to increase the tractive effort.

The most important characteristic of any gear mechanism is “ gear ratio", Which is determined by the ratio of the number of teeth on the driving and driven gears. To obtain the gear ratio of the GP, you need to divide the number of cardan revolutions (larger number) by the number of revolutions made by the wheel (smaller number) For example, the cardan revolutions are 37, and the wheels are 8, we divide 37/8 we get the gear ratio 4.625

On UAZ Patriot with Spicer-type bridges, until 2015, GP 4.11 was installed on gasoline models, and GP 4.625 on diesel ones. Now GP 4,625 are being installed on all UAZ Patriot models. There are tuning kits with GP 5.14 and 5.29.

Victor confirmed that there is such a case. He said that he would get out of the situation by installing a more momentary GP.

Photos from rolling on the landfill. Can be compared with the "standard" car UAZ Patriot "Yeti" on 32 wheels

In the BALU, you somehow feel calmer when the car rolls. Due to the wider track, roll is less, and due to the width of the wheels themselves, there is no tendency to self-entrainment.

But there was also one drawback.

Has flattened the left front wheel

Tried to pump with a compressor

But it was not there. The air was etched from under the tire-disc connection. Apparently due to the fact that the sealant was not reported during assembly. (And about the wheel assembly below) It is necessary to reassemble the wheel. BALU left for the service area.

There was a time for which the General Director of AVTOROS Vladimir Volkhonsky spoke about the model range of low-pressure tires, production and problems associated with business in Russia

A whole sea of \u200b\u200btires

But before connecting the disc into a single whole, a tire is put on it and a spacer disc is inserted.

The spacer disc prevents the tire from compressing when the tire pressure is at its lowest.
To fix the tire on the edge of the disc, it is coated with sealant during assembly.

We looked at the tire in section

Two layers of cord are clearly visible.

While we were looking at the tire economy, UAZ BALU was restored and ready for new adventures.

Which were not long in coming.
In the summer of 2015, the ABT festival was held under the direction of Alexander Trushnikov, where BALU also demonstrated its capabilities.

The roads on Chukhloma are very different: from snow-covered, with ice, to dirt roads with ruts, muddy from water.

BALU drove on all soils better than the other eight cars in the team.

There was a lot of water, the snow had just melted. The narrow wheels "cut" the ground and began to slip. BALU was just driving on low pressure tires. Moreover, the tread can be cleaned very well.

A video where you can see UAZ BALU at Polnaya Chukhloma 2015 (and there is a full video from PPCh 2015)

But there were some incidents :(

At zero speed, when cornering in place, the rear left wheel almost unscrewed.
An autopsy revealed that it had cut off the studs that secure the spacer. It's a miracle that this happened not on a 500-kilometer stretch from Moscow at a speed of 90 km / h, but here.
From the excuse, we found out that this particular wheel was removed before the trip and, apparently, the studs were not tightened.

But after that I completely stopped respecting the spacers. An unnecessary and dangerous thing.
The hairpins were replaced.

But, then, they monitored the condition of the studs and spacers - everything was fine, there was no urge to unscrew.

Of the minuses - the wheel was cut. Where this happened is not clear. Found after the end of the PCh.

But BALU has always been in the spotlight.

To summarize everything: the project is very interesting, this type of wheel has its pros and cons.

Pros: the rubber is soft, flattens well, allows you to reduce the pressure to 0.15 kg / cm and at the same time do not disassemble. On the highway, it goes quietly 90 km / h, the car, while keeping on the road confidently. However, there is vibration and hum from the tread, which can be reduced to some extent by "playing" with the tire pressure.
Works well on loose but unbroken soils.

Cons: noisy on the track, afraid of cuts, under strong shock loads, the inner spacer ring may break and the tire will start to “pickle” along the rim. Installation requires modification of the suspension and the car (lift, cutting arches, spacers). Installation of more powerful GPUs is desirable. Due to the large track width, the car does not fall into the standard track and moves with a load on either side, while the risk of breaking the spacer ring increases.

The TREKOL company produces three models of ultra-low pressure tires that are suitable for installation on all-terrain vehicles based on UAZ bodies. Wheels can be installed both on machines serially produced by TREKOL itself, and on self-made ones.

Tires manufactured by TREKOL can be used for a wide range of vehicles. Tubeless tires turn a familiar car into a cross-country vehicle that easily overcomes virgin snow and swampy plains. Where roads are not yet built, you can become a pioneer.

Tires for all-terrain vehicle UAZ

Designed for off-season weather conditions, they are suitable for traveling on washed-out country roads and bumpy ruts. The basis is a flexible rubber-cord casing. It is thanks to her that the wheels, without falling into the ground, slide over the surface and easily adapt to unevenness of the road. The tight connection to the rim prevents twisting, which results in a low pressure of 0.1 to 0.6 kPa. This guarantees efficiency - with a small impact on the ground, energy losses for resistance are prevented.

The tires for the UAZ "Bukhanku" all-terrain vehicle and other models of the manufacturer have one more feature - they are easy to operate. Since they are tubeless, this reduces their weight and allows you to repair minor damage without dismantling.

For hunting and fishing

Fishing and hunting farms have already appreciated the advantages of UAZ snow and swamp vehicles. The model range includes a number of swamp vehicles and snow and swamp vehicles, for which the TRECOL wheels have become a guarantee of high cross-country ability. Low pressure and elasticity allow you to move without problems on virgin snow, wetlands or sandy soil. Even when driving on soft ground, the low pressure tires do not cut through the track, which saves fuel and preserves vegetation.

On a UAZ off-road

Car enthusiasts who have experimented with low-pressure wheels have already appreciated their capabilities. The technique was tested on virgin snow and swampy forest swamps. For fishing trips, such all-terrain vehicles are simply irreplaceable, since they have no equal in cross-country ability. Cars with low-pressure tires, modified by car enthusiasts, pass without problems where heavier vehicles cannot pass. And for traveling on the tundra, motorists consider the UAZ all-terrain vehicle to be an ideal option.

For professionals and amateurs

Low-pressure tires in the configuration for UAZ will allow you to drive off-road. Professionals, lovers of fishing, hunting and travel have already appreciated the benefits of low pressure tires.
