Tire pressure VAZ 2107: what it depends on and what it affects

January 22, 2015 Lada.Online 868 462 The size of the tires and wheels greatly influences the behavior of the car on the road. AvtoVAZ recommends installing tires and wheels of a strictly defined size on Lada 4×4; only in this case the manufacturer guarantees the service life of chassis and suspension components and assemblies. In the review, we will tell you what the size of the wheels affects during the operation of the machine and what recommendations the manufacturer gives.

About winter tires on Lada 4×4

When choosing tires for the winter, use the table above. In addition, it is allowed to use winter tires (M+S) of the above dimensions and index Q with a corresponding limitation of the maximum vehicle speed (up to 160 km/h).

Choose winter tires on your Lada 4×4 that are as narrow as possible so that the pressure of the car on the surface is greater, this will improve traction. Also remember that wide tires are more sensitive to the ruts on the road.

Which wheels are better to install on Lada 4×4

The choice of tires for R16 wheels is not large; most often they choose sizes 185/75 R16, 175/80 R16, or 215/65 R16. Due to the paucity of choice, many SUV owners install R15 wheels on their Lada 4×4.

R15 wheels can be borrowed from Chevrolet Niva wheels, which fit without modifications. Thus, the choice of tires will increase significantly and you will be able to choose the appropriate tires for certain operating conditions. In addition, a car with such wheels will look more stylish. In addition to standard tires for R15 wheels, you can install 205/75 R15 tires.

Do you dream of a Lada 4×4 on big wheels , but are not going to cut the arches? The maximum tire size for a Lada 4×4 without modifications is 215/75 R15, and the rims must have an offset of 40, otherwise the tires will touch the fender liners. Finally, install alloy wheels on your Lada 4×4 and you will get a stylish SUV!

When choosing wheels, you should take into account the full diameter of the wheel; it should not differ much from the standard one. Compatibility table for Lada 4×4 tires and wheels:

Green indicates the minimum deviation of the wheel diameter (up to 3 mm); Orange indicates a diameter deviation from 3 to 6 mm.

Don't forget about the rim width:

When installing tires or wheels that differ in parameters

from those recommended by the factory, you can:

• be refused warranty repair of the chassis;
• be stopped by a traffic police inspector, who has the right to draw up a report on the car’s non-compliance with the requirements of the Technical Regulations;
• fail to pass technical inspection.

What does the size of tires and wheels affect?

Increasing the diameter of the disk Increasing the width of the disk Increasing the width of the tire

The smaller the unsprung masses

(this includes a lot of tires and wheels), the better the car will hold the road and accelerate faster. For example, if you put wheels on a car that are 2 kg lighter each, then acceleration to 100 km/h will be reduced by 0.2 seconds.

What pressure should Niva tires have?

VAZ, which produces various 4x4 SUV models, which include modifications 2121, 21213, 21214 and 2131, defines one value for all. Thus, the manufacturer recommends pumping the wheels of the front axle of an SUV to 1.9 Bar, and for the rear axle - 1.8-1.7 Bar. However, some parameters depend on the wheel size.

In summer

However, the above are standard parameters. Much depends on the time of year and operating conditions of the car. In summer, these conditions are close to factory conditions, so the figure of 1.9 can be considered acceptable. But if you are planning a long trip along the highway, then you can increase the value to 2-2.2 Bar. This approach will improve the car's running speed and save 0.5-1 liter of gasoline per 100 km. However, this only applies to flat roads - if the road under the wheels is far from ideal, it is better to leave the indicator as standard.

What wheel sizes does the manufacturer recommend to install?

The VAZ 2131 Niva 2131x 2009 1.8i is equipped with 5Jx16 ET58 rims assembled with 175/80 R16 88Q tires as standard. Where:

• 5J - rim width in inches;
• 16″ — tire diameter in inches;
• ET58 - disc offset in millimeters.

The vehicle tire marking 175/80 R16 is deciphered as follows:

• 175 — profile width (cross section of the tire) in millimeters;
• 80 - profile height as a percentage of its width;
• R - radial cord winding;
• 16 is the tire diameter in inches.

In addition, information about its load capacity and speed parameters can be printed on the rubber - load index and speed index. The load index is a two- or three-digit number; the speed index is indicated in Latin letters, for example 88Q:

• 88 - maximum permissible tire load 560 kg;
• Q — maximum permissible vehicle speed is 160 km/h.

Using the recommended tire sizes will help you avoid problems with handling, safety and other difficulties. What non-standard sizes can be supplied? Refer to the table; it indicates possible acceptable alternative sizes for tuning. Although there are other options that we have not described in the table. For example, wider discs of the same diameter. Or install wheels of the same width, but with a larger diameter, which is quite popular among car owners. The choice of discs is huge; you can find copies with the same parameters, but with an overhang 1-2 millimeters more or less. It is not possible to list all the options.

Summary table of Niva tire pressure

However, there are “critical indicators”. For long drives on the highway and minimal fuel consumption, you can inflate the wheels to 2.2 bar. If you plan to drive in icy conditions or off-road, you can reduce the pressure to 1.5 or even 1 bar.

Below is a table of recommended pressure values ​​for different Kama Flame tire sizes.

(see also Tire and Wheel Sizes)

Tire pressure should be checked monthly or before each long trip. The pressure is measured on cold tires (after the car has been parked for 3 hours or more, or after the car has been driven for a distance of no more than 1.6 km).

• The air pressure in a heated tire can increase by 41 kPa compared to a cold tire.

• Exceeding the recommended tire pressure leads to the following consequences:

♦ deterioration in smoothness and ride comfort; ♦ damage to the tire carcass; ♦ rapid wear of the tread in the central part of the treadmill.

Expert advice

When choosing tires for a car, you must first follow the manufacturer's instructions. Ask yourself a few questions.

• On what roads will the car be primarily used?
• Do you need increased cross-country ability?
• How much of the route will be city roads and how much will be highways?
• Will the vehicle carry heavy loads?

The answers to these and similar questions will help determine which tire parameters you need to pay special attention to.

How to choose the right wheels for VAZ 2131 Niva 2009?

• Stamped (economical price category) - made from a sheet of iron by stamping on a press.
• Light alloy - manufactured by casting (more reliable than stamped ones).
• Forged (the highest quality and more expensive than the previous ones) - made from light alloys by stamping at high temperatures.

The choice depends on financial capabilities. However, it should be borne in mind that the quality of the road surface on which you have to drive every day must also be taken into account.

So, if it gets into a hole, a stamped disk will bend and will not cause harm to the tire, but a forged or cast one can cut it. There is a possibility that the cast disc may burst or crack.

It should also be noted that repairing “stamping” wheels is cheaper than repairing cast or forged wheels. But wheels with high-quality cast and forged disks kill the suspension less, because lighter and have more perfect geometry (better balanced).

The same wheels may or may not rub with tires on the same car - wheel alignment adjustment will help here.

Instruments for checking the degree of pumping

For cars such as the Chevrolet Niva, maintaining this parameter is especially important. The center of gravity of this car is high, and the car cannot be called stable, especially during emergency maneuvers. It is impossible to measure the degree of air compression in a tire without special measuring instruments.

Pressure gauges are used for these purposes. They are divided into two categories that differ structurally:

1. Mechanical pressure gauge. A device for measuring tire pressure, having a mechanical drive and a dial indicator. Has a significant degree of error, long service life, does not require a power source.
2. Electronic pressure gauge. Electronic type device with a screen for displaying measurement data. It is powered by an internal power source; when used correctly, the error tends to zero.

Important: The error of devices of the first type is greater in winter than in summer due to temperature deformations of mechanical parts. In cold weather, it is recommended to use only to get to the garage or service station. The disadvantage of electronic pressure gauges is that the battery can run out at the most inopportune moment.

Frequency of measurements on Chevrolet Niva

In order not to endanger your life and the lives of others, you need to check the tire pressure before each trip, especially over long distances. The sequence of actions is as follows:

What should be the pressure in car tires?

Good afternoon, we present to your attention relevant material for any car enthusiast on the topic: what pressure…

1. We check the readings using a pressure gauge as indicated in the instructions for it. Tires should not be warm. The car must sit for three hours.
2. We compare the readings with the data in the table of permissible tire pressure for the Niva 21214 car.
3. After 30-40 minutes, we repeat the measurement, and if the readings become low, it means there is a puncture. Keeping the data at the same level indicates that you can leave.

Dimensions, weight, load capacity

The vehicle has characteristics such as length, width, height. These indicators help the driver assess how much space the car occupies on the road. Length is the distance between the maximum protruding parts in front and behind. The width is determined by the boundaries of the side mirrors. Height is measured from the surface on which the vehicle is located to the highest point on the roof of the vehicle.

All this data is not difficult to find in the vehicle operating manual. Dimensions Niva 2131:

• length – 4240 mm;
• width – 1814 mm;
• height – 1640 mm.

dimensions

For Niva 2131, the outer minimum turning radius along the axis of the front wheel track is 6.45 m. Equally important indicators are weight (curb weight) and load capacity. The first is the total mass of a set of standard equipment, all necessary consumables (including engine oil, fuel, etc.), as well as the weight of the driver. Baggage and passengers are not included. The 5-door Lada Niva 4x4 weighs 1370 kg.

What pressure should Niva tires have?

To always know what pressure gauge readings are considered normal, print out a table of acceptable readings and carry it in the glove compartment (if the metal plate on the car body is missing or has become unusable), and the pressure gauge in the trunk. In the cold season, the road surface is slippery and the tires are less elastic. Therefore, in winter, tire pressure should be lower than in summer. The permissible run-up is 0.2-0.3 bar.

Due to this, the area of ​​the contact patch increases and the grip on the road increases. The standard pressure in Chevrolet Niva tires depends on the parameters of the ramp indicated on its sides. The table shows data for 205/75 R15, 205/70 R15 and 215/65 R16. These data are identical for the Chevrolet Niva 21214 and Niva 21213 models. In some emergency cases, it is possible to make the injection rate lower than recommended.

So, the pressure in the tires of a Niva Chevrolet in winter can be reduced to 1.2-1.5 atm if you get stuck in the snow. This will allow you to get out, but immediately after leaving on solid ground, the indicators must be brought to normal. The Chevrolet Niva, although an SUV, is not an all-terrain vehicle, and can get stuck not only in winter. What pressure to set depends on the type and degree of tread wear.

• Q — maximum permissible vehicle speed is 160 km/h.

Consequence of violation of regulatory pressure Niva 21213

If you do not adhere to the described operating requirements, the following will happen:

1. Increased load on chassis parts will lead to premature wear and failure.
2. Fuel consumption will increase due to the fact that the flat tire has a larger contact area. The protector, having opened, prevents movement. The engine will need to develop more power.
3. The tires will wear out quickly. The reason for this is the increased contact patch with the road surface. By the way, lateral abrasion indicates that the tire is flat, and it is necessary to urgently take measurements and eliminate the cause.
4. The risk of getting into an accident increases significantly, especially if you overinflate your tires in winter.

But if you monitor the amount of air in the slopes, the Chevrolet Niva will always remain a safe car with outstanding cross-country characteristics.

Tires for even greater cross-country ability: 235/75 R15 and 240/80 R15

For those for whom standard cross-country ability is not enough and want to go into the real wilds, then you just need to take R15 tires with this dimension (235/75) and put it in the Niva. These dimensions will make the car a real jeep, which will essentially go everywhere it can go. So whoever has such goals should put such wheels on the Niva.

But it’s not so simple, in order for such tires to become normal, you will have to do a lifting, this is a kind of tuning of the Niva. You'll have to raise the suspension and widen the wheel arches. But this is not a problem at all, because even at the plant in Togliatti there are special lifting kits, thanks to which the wheel axle can be made lower by 4 cm, which will be enough to install such off-road tires R15 235/75.

The lifting kit includes:

If you install this kit correctly, the shock absorbers and springs will fit as they should. But that’s not all, for a full ride you still need to make some changes: change the pairs of front and rear gearboxes. If they come from the factory 3.9, then you need to put 4.44. The result will be increased acceleration dynamics, and there will be less load on the engine and clutch.

You also need to remember that there is also an offset of the wheel rims, this parameter needs to be increased slightly, for this you need to make special spacers from aluminum alloy and install them in the hub. Masters usually know how to do this.

After such improvements, the hub assembly will operate under increased loads, so it is recommended to install hubs with 2-row bearings on the steering knuckle. This kind of Niva tuning will require a little time and money.
