An important aspect in ensuring the tractor's cross-country ability are pneumatic tires that directly provide power transmission to the moving surface. The grip characteristics of tires determine the driving and traction qualities of the tractor when moving under load as part of units and in off-road conditions, as well as when working in the field on soils with different physical composition and degree of humidity. The article will describe the brands and sizes of tires for the Belarus tractor. As well as options for combining the sizes of front and rear tires to complete an all-wheel drive tractor, taking into account the type of front drive axle.
Tire brands and sizes for MTZ 80, MTZ 82.1, MTZ 82.2
There are two types of tires made for tractors: radial and diagonal. Products are marked in two standard sizes, inch or metric. The first digit in the abbreviation indicates the designation of the profile width. The second number indicates the tire diameter (rim) size. Radial tire brands are marked in front of the seat size with the Latin letter R; there are no diagonal letter designations. Low-profile tires are designated by the letter L, for example, 18.4L-30. An additional number in the size designation indicates the ratio of the profile height to its width, for example, 360/70R24.
Front wheel tire sizes on MTZ 82
The table shows tires for front drive axles installed on MTZ 82 tractors of its modifications.
On the front axle of the MTZ 80 for steering wheels, grade 9.00-20 tires with W8, W7 disks are installed
Rear wheel tire sizes on MTZ 82(80)
According to experts, diagonal tires are stronger and lower in cost, but unlike radial tires they wear out faster, their use is more damaging to the soil and increases fuel consumption.
Tire (rubber, wheel) MTZ-80 (Belarus 4x2): front, rear size and recommended pressure
on the conveyor as standard on the MTZ-80 :
Front - 7.50-20 or 9.00-20
Rear - 15.5-38
What pressure must be maintained in the tires on the MTZ-1221?
The exact pressure for each tire is set by the tire manufacturer.
For example, for a 7.50-20 , the manufacturer recommends maintaining a pressure of 160 kPa or 1.6 Bar
Volzhsky Tire Plant (Voltyre) adheres to the same recommendations for its tires: .
15.5-38 rear tire, the recommended operating pressure differs for different modifications, depending on the number of layers: 8/10/16: 1.6/2.0/3.2 Bar respectively.
For products from the Volzhsky Tire Plant (Voltyre), the recommended operating pressure also differs for different modifications, depending on the number of layers: 8/10/16: 1.6/2.0/3.1 Bar , respectively.
Selection of tires depending on the tractor model and FDA type
When equipping the MTZ 82 tractor with a front drive axle, it is important to match the sizes of the front and rear tires. Since the tractor has all-wheel drive, the tire size affects the final gear ratio of the drive wheels, which affects the speed of movement. To ensure synchronous action of traction forces from both drive axles, the gear ratios of the front and rear wheels, with the FDA engaged, must correspond to each other. In case of non-compliance, the traction and driving qualities of the tractor will be reduced, and loads will arise in the transmission mechanisms and the tractor FDA drive, leading to untimely wear and failure of parts.
Combination of rear and front tires for MTZ 82.1 with a portal front drive axle
Combination of tires for MTZ 82.2 with beam FDA
In tractors using only the rear drive axle, size matching when equipped with tires does not matter. When installing a larger rear tire diameter than what is declared by the factory, the speed in gears will increase.
Models
Modern manufacturers of tires for agricultural machinery and special equipment offer a wide selection of products for tractors and other equipment.
Among all the offers on the market, the following should be highlighted, having dimensions for any model in Belarus and not only (MTZ-80 tires are taken as an example):
- Belshina - designed for installation on the rear (drive) axle, has a unique tread pattern, and allows the vehicle to move on any surface. Excellent tire for little money.
Belshina
- Nizhnekamskshina (KAMA) is a common tire that has proven itself only from the best side. There are models for the front and rear wheels of the tractor. The cost is not very high, and the quality, as always, from this manufacturer is excellent.
- Altai Tire Plant - a huge selection of products allows you to choose tires for any needs, and the price-quality ratio is one of the best on the market. Allows you to put high-quality tires on your tractor for little money.
Important: tires for tractors, in most cases are designated F-2A - rear wheels, F-35 - front wheels. Almost all manufacturers use such designations, and owners choose only the manufacturer. There may be additions to the designations that indicate additional properties of the tire, but the main ones are just that (when not indicated, you need to choose based on the diameter of the wheels).
Load and speed index in tire markings
Additional numbers and letters, regardless of size, in the product brand indicate the operational load and speed index, indicating the maximum load that the tire can withstand at the operating pressure in it at maximum operating speed. In the abbreviation after the brand-size, the first three digits indicate the load indicator, then the speed indicator in the form of a letter with a number.
Load index table
Particular attention should be paid when selecting tires for vehicles with loading equipment, where the load on the chassis increases. Typically, strength is confirmed by the number of layers of cord of a product, according to which a load index (load capacity) is assigned. For excavators based on MTZ 82(80) and tractors with front-end and grab loaders, tires are selected based on the additional weight of the loading equipment, taking into account the weight of the full load of the bucket or the load being lifted.
Speed index table for cx tires. technology.
The standard set for the MTZ 82 is two rear tires with an index of at least 130 with a load capacity of 1900 kg each and a pair of front tires with an index of at least 115 with a maximum load of up to 1215 kg. Thus, the total strength potential of all four pneumatic wheels of the machine will be more than 6000 kg, which exceeds the operating weight of the tractor by 50%. The speed index for wheels for MTZ is chosen within the range of A6, A7, A8. In this configuration, the tire strength potential is sufficient for using the machine with mounted machines in various units.
When constantly using a tractor with an excavator or other special equipment that increases weight, it is recommended to select tires with indicators that provide a 100% safety margin.
Pressure
All-terrain tires are installed on tractors, allowing them to move on absolutely any surface, including deep snow, asphalt, mud and clay. To preserve the rubber, it is necessary to monitor the pressure and condition of the wheels. This is due to the fact that in order to operate Belarus in various conditions, it is necessary to pump up, deflate or pump over the pressure in order to keep the wheels in order and without cracks. Normal pressure without load is: rear - 2.5 atmospheres, front tire MTZ - 1.5 atm. When working with a load, you must refer to the operating instructions - find the required section, select the type of work that needs to be carried out, and select the pressure.
Pressure table
Example: during transport work, the pressure of the MTZ rear tire is 1 atm, when working with attachments - 1.4.
Purpose of agricultural tractor tires for MTZ 82(80)
In addition to the indicators described above, rubber for tractors is divided according to its purpose. The tread pattern and its width determine the intended use of pneumatic tires. For tractors, rubber is produced with four types of treads:

V.I. Lenin” since 1979. Wheeled, universal, traction class 1.4, with four driving wheels. It is a modification of the MTZ-80 tractor. Designed to perform agricultural (pre-sowing tillage and inter-row tillage of row crops, planting potato seedlings, preparing feed and servicing livestock farms, harvesting crops) and transport work in conjunction with mounted and trailed machines. It differs from the basic one in the presence of a front drive axle and a drive to it. While maintaining all the qualities of the base model, including versatility. It has increased traction and traction properties and cross-country ability. The front drive axle is a beam that swings in the eyes of the front beam and rests on coil springs mounted in the final drive gearboxes. The main gear consists of bevel gears with a spiral tooth.
The front axle differential is conical, self-locking. The final drives of the front axle are made in the form of final drives with two pairs of bevel gears, which simultaneously serve as constant velocity joints.
The transfer case, which transmits torque from the gearbox to the cardan drive of the front drive axle, is a single-stage gear reducer with a roller freewheel. The transfer case is switched on and off when the tractor is moving forward automatically using a freewheel at the moment when the slipping of the rear wheels exceeds the set value. The design of the transfer case provides for the possibility of forcibly engaging and disabling the front drive axle both during rearward and forward movement of the tractor, depending on operating conditions.
The cardan drive transmits torque from the transfer case to the front axle. It consists of two identical design and length rear and front cardan shafts and an intermediate support with a safety friction clutch.

Tractor tires - features and nuances
It is worth immediately noting that the MTZ-80/82 chassis has some differences, the essence of which is as follows - the MTZ 80 is equipped with rear drive wheels, while the front ones perform guiding functions. At the same time, on MTZ 82 the rear wheels are also driving, while the front wheels combine driving and guiding functions. Moreover, in both variations, the tires are made on a pneumatic basis.
When choosing tires, here you should first of all mean the rear ones; you must also take into account the fact for what kind of work they will be used in the future; their size depends on this. So, the following variations are possible (all sizes are presented in inches):
The choice of optimal pressure depends primarily on the type of work being performed, and, accordingly, on the selected wheel size.
Table of permissible loads on tractor tires.
Load change table.
Table: Types of work and modes of internal tire pressure
Where can I buy
You can purchase tires at any specialized store, where tractor owners will be advised by experienced consultants and will help you choose the appropriate model individually for each client.
An analogue of branded centers are sites for the sale of used goods (Avito, for example). But there will always be a risk of such a purchase, because the history of the wheels is unknown - without knowing how the wheels were used, you can buy tires or wheels in poor condition. Therefore, when buying used tires on Avito, owners need to be as careful as possible and clearly understand what tires are needed.
The bottom line can be summed up as follows: in order for tractor tires to serve for a long time and help perform all the functions of the tractor, it is necessary to monitor them properly (pressure, dimensions). If the wheels are properly and appropriately cared for, their service life will increase and you won’t have to buy new ones.

Operation and maintenance of tires on MTZ tractors
The operating parameters of the vehicle, its cross-country ability, performance, and fuel consumption largely depend on the condition of the tires. That is why their operation and maintenance must be approached with the utmost care and caution.
In order to prevent excessively rapid wear and tear, you need to follow a few simple, but no less effective rules, the essence of which is as follows:
- Adhere to the prescribed internal tire pressure standards, which depend on the load and operating conditions of the tractor;
- Control the movement at high speed - there should be no steering to the side. If this still occurs, stop and pump up the wheel with the lowest pressure;
- Avoid sudden braking and prolonged slipping;
- Try not to leave the tractor on soil that is contaminated with petroleum products;
- Carry out periodic maintenance and inspection of wheels;
- Do not use the front axle on dry roads;
- Do not allow the wheels to wobble or wobble.
Afterword
The correct choice of tires, their proper operation and timely maintenance will not only allow you to use your equipment with maximum efficiency, but will also extend the life of its safe operation, which will ensure that you solve all the necessary problems at minimal cost.
When purchasing tires, it is extremely important to take into account the modification of the tractor, as well as the type and size of the elements. In this article we will tell you about the most important features of choosing tires for the MTZ tractor.
So, when mounting wheels on a tractor, the air mixture is pumped into the chamber using a valve. The part is equipped with a spool - a modification of the check valve. The valves on the rear wheels are designed in such a way that a device for filling liquid is connected to them.
This is needed to ballistize the vehicle.
Dimensions of front and rear tires for wheels of MTZ 82 drive axles
An important aspect in ensuring the tractor's cross-country ability are pneumatic tires that directly provide power transmission to the moving surface. The grip characteristics of tires determine the driving and traction qualities of the tractor when moving under load as part of units and in off-road conditions, as well as when working in the field on soils with different physical composition and degree of humidity. The article will describe the brands and sizes of tires for the Belarus tractor. As well as options for combining the sizes of front and rear tires to complete an all-wheel drive tractor, taking into account the type of front drive axle.
MTZ tires - types and sizes
For modifications MTZ-80 and 82, certain tire sizes are provided:
- Front wheel of the 80th modification - 7.5-20;
- Front wheel 82-1 model – 11.2-20;
- Rear wheels in both versions – 15.5-38;
- Rear tires to order - 9-42;
- Front tires to order - 18.4-30.
The use of such standard sizes is necessary when working in a narrow space between rows of row-crop plants, as well as when performing road construction work. Therefore, when choosing MTZ tires, be sure to take into account the standard size.
Features of the radial shape
The structural difference between the MTZ rear tires is the radial placement of the cord threads inside the carcass and the reinforcement of the breaker. In standard models of diagonal format, the threads form an angle with the profile within 50-54 degrees, in radial ones - up to 5.
Due to the radial direction of the cord thread, the flexibility of the sidewall increases. Strengthening the belt ensures the resistance of the MTZ tire to maximum circumferential compression. The advantages of this option are:
- Increased deflection and print area upon contact with the ground;
- Improving tire quality;
- Increasing the traction and grip characteristics of the machine;
- Reducing slippage;
- Reduced soil compaction;
- Increased tread wear resistance.
MTZ tractor tires wear out quite quickly, and their cost is about 12% of the price of the tractor. In many ways, it is these components that determine the efficiency and performance of the machine. The condition of the tires affects traction and grip parameters, cross-country ability, and fuel consumption. Therefore, if you are looking for tractor tires, we advise you to carefully select components from trusted suppliers.
In addition to the distinctive size of the circumference and width of the rim in relation to the corresponding tire size and brand of tractor, the location of their installation on the front or rear axles, the discs are divided according to their design:
- welded - with a constant offset, that is, the disc and rim are welded
- discs with variable offset, where the wheel disc is attached to the rim on brackets and can, if necessary, be rearranged relative to the center of the rim axis
- additional rims are produced for doubling the running wheels of energy-saturated brands of tractors in the corresponding size of the used disk
front wheel MTZ 82 assembled with a welded disk
rear wheel MTZ 82
Front wheel MTZ 82 with variable offset
The offset in the characteristics is designated as ET, where the value indicates the displacement distance of the wheel hub flange mounting plane relative to the center of the rim rotation axis. This parameter is especially important for row-crop tractors, where it is necessary to form a tractor track of a certain width in accordance with the agrotechnical requirements of the cultivated crop.
Wheel parameters
Also, when choosing a disk, you need to specify the number of mounting holes and their location relative to the center of the plane of connection with the hub flange. And also the very diameter of the central hole for the hub, just like a number of wheel rims, having the same markings and tire seat parameters, may differ in these parameters depending on the tractor model.

Appearance and varieties
In appearance, the tractor does not differ from its analogues, but due to the location and size of the wheels, it is one of the most practical and versatile vehicles. The rear wheel has dimensions 16.9R38, and the front one – 14/9R24 (dimensions are given for MTZ-1221). The model has full drive, and allows you to cope with all tasks in any weather conditions.
There are a huge number of models and modifications - some of the most common are:
- MTZ-80 - tire size is: for the front 9.00-20 (7.5-20), for the rear 15.5R. Used in agriculture, utilities, and other areas.
- MTZ-82 - tire sizes are: front - 8.3-20, rear - 15.5-38. It is used during construction work, watering roads, etc.
The models described above hide enormous potential - they are used in almost all areas of life, due to their versatility in mounting various equipment, and have a 4*2 drive. There are modifications of the described models - MTZ-80X (with one front wheel), or MTZ-820 (4*4 drive). In addition to this tractor, the Minsk Tractor Plant produces tractors to suit any needs of the owners, and models can be selected individually, according to the required operating criteria.
Issues of installation, replacement and repair of MTZ wheel rims
The installation of the front and rear wheels of MTZ tractors is carried out in a standard way: the wheel is mounted with a disk on studs (bolts) in the hub, and screwed with conical nuts. However, there are a number of points to pay attention to.
First, before completely removing the wheels, you should first loosen the flare nuts, then jack up the wheel and finally remove the nuts. The wheel is installed in the reverse order - first the nuts are tightened by hand, then the wheel is lowered to the ground and the nuts are finally tightened with a wrench. The nuts are screwed crosswise, making sure that they fit tightly to the disk and are screwed with the force specified in the instructions.
A loose or damaged nut leads to cracks and deformations on the disc. Therefore, you should periodically check that the disks are securely fastened, and if even one nut breaks or is lost, it should be replaced immediately.
When changing the front wheel track, you have to perform the following actions with the disks:
- When switching to the track range from 1200 - 1500 mm to 1500 - 1600 mm (or vice versa), the support disk is removed from the rim and placed on the inside of the stops (brackets). In this case, the recesses in the disk allow it to pass through these brackets;
- When switching to the range of 1600 - 1800 mm, the wheels are completely removed and simply swapped, leaving the correct direction of their rotation (it is indicated by an arrow on the tire). That is, the right wheel is put in place of the left one and vice versa.
The rear wheels make it possible to change the track in steps up to 1800 mm, for which the wheels are also swapped, but in this case the replacement is carried out together with the hubs.
When installing paired (twin) wheels, special spacers are used. In this case, it is often necessary to press short bolts out of the hubs, replacing them with longer ones - this makes it possible to immediately screw the inner wheel disk and spacer onto one bolt. The outer wheel is mounted on studs pressed into the spacer.
Whenever you replace tires and tubes, it is recommended to subject the wheels to simple maintenance: clean and wash, remove nicks, remove rust, remove burrs, and finally paint (to protect against corrosion). If the disk has excessive deformations, then it should simply be replaced with a new one.
Proper selection and operation of wheel rims is the key to achieving the declared characteristics of the MTZ tractor and high-quality performance of any type of work.

In Russia there are people who own small farms used for commercial purposes, and some of them simply buy a large amount of land for a comfortable life. To cultivate more than 1 hectare of untouched land, agricultural machinery will be required. In such cases, the Minsk Tractor Plant offers a miniature model of the MTZ-82 tractor, popular for private use, which helps fulfill all the owner’s needs for caring for a large piece of land.
Front wheel disks MTZ 82 (80)
For the Belarus tractor there are welded wheel rims with a constant offset and with a variable offset. All-welded ones are mostly used with a portal-type drive axle with bevel pairs of gears in wheel reducers and are divided into disks with mounting for an old-style hub with 5 studs, and for a new-style front wheel hub with 8 studs.
In addition, within the same size, welded tractor disks differ in their design by the offset ET (meaning the offset of the hub mounting plane on the disk relative to the central axis of the wheel rim).
Welded front discs
The most common rim size W9x20 is used on the front wheels of the following brands of Belaus tractors of the 1.4 t.h. traction class: 510, 520, 570, 512, 522, 532, 572, 592, 820, 82.1, 892, 920, 952. They are equipped with 11.2 tires -20 with landing parameters: rim width -228.6 mm, landing diameter -512.8 mm. Since this size has mounts to the hub with 5 and 8 holes, and an offset of +80 and +32 mm, there are six varieties of these wheels.

When forming wheels with tires, it must be taken into account that changing the size of the wheel assembly will affect the final speed of the tractor. In the technical documentation for the tractor, the manufacturer indicates the gearbox speeds according to the established tire sizes. You also need to take into account the factor of compatibility of the tire sizes of the rear and front wheels recommended by the factory on tractors with two drive axles. Dimensions that do not match can lead to uneven wear of the front tires, as well as to unwanted loads in the FDA mechanisms, its drive and transmission when all-wheel drive is engaged.

Operation and maintenance of tires on MTZ tractors
The operating parameters of the vehicle, its cross-country ability, performance, and fuel consumption largely depend on the condition of the tires. That is why their operation and maintenance must be approached with the utmost care and caution.
In order to prevent excessively rapid wear and tear, you need to follow a few simple, but no less effective rules, the essence of which is as follows:
Adhere to the prescribed internal tire pressure standards, which depend on the load and operating conditions of the tractor;
Characteristics of road wheel disks for the MTZ 1221 tractor
Considering that the Belarus 1221 is equipped with a reinforced beam FDA with planetary wheel gears, which has limited possibilities for changing the width of the beam, the disks of the front wheels of the tractor have a design with the possibility of forming a variable offset.
