What pressure should be in the tires of VAZ cars

The manufacturer of both the car and the tires always recommends maintaining a certain tire pressure, and the tire pressure on both the front and rear axles does not necessarily have to be the same. It all depends on the load on the car, weight distribution, and weather conditions.

If the wheel has high pressure, then:

1. The resistance coefficient decreases.
2. Less susceptible to deformation.
3. The point of contact with the road is reduced.
4. Low shock absorption.
5. High controllability.

If the tire has low pressure:

1. The point of contact with the road increases.
2. The resistance coefficient increases.
3. Consumption increases.
4. More comfort on uneven roads.
5. Low controllability.

The tire consists of 2 main parts: Tread and sidewall. The protector is a dense material that is not very susceptible to deformation. The sidewall, on the contrary, suffers greatly from both low and high pressure.

At low pressure, it is possible that the rim of the disk will cut through the tire on a bump or hole, and you, at best, will not be able to continue driving on such a “wheel.” And with high pressure, upon impact, a hernia may pop out or simply burst. But we are talking about pressure 2 to 3 times higher than normal; if you overinflated the tire by 10-15%, then there is nothing catastrophic about it.

WHAT IS THE RISK OF DEVIATION FROM THE SET PARAMETERS

Front-wheel drive cars of the Volzhsky Automobile Plant, such as the VAZ 2110, VAZ 2114 and VAZ 2115, can be equipped with wheels with a radius of R13, R14, R15 and R16, but the standard cars are equipped only with rims and tires of the 13th and 14th radius. The optimal tire pressure depends primarily on the load and weight of the vehicle; much also depends on road conditions and ambient temperature.

If the wheels are poorly inflated, then:

• The tire tread will wear out faster;
• It will become more difficult to control the car and turn the steering wheel harder;
• Fuel consumption will increase, and the more flat the tires, the more noticeable the gasoline consumption;
• The car will become prone to skidding, especially on wet and snowy roads, and stability will be lost;
• The power of the car will decrease as the resistance to movement will increase.

If the wheels are inflated more than normal, then this is also not very good:

• When driving, you can feel all the unevenness of the road surface and the ride becomes uncomfortable. In addition, the chassis wears out faster;
• Due to less grip on the road surface, the braking distance is longer, which has a detrimental effect on traffic safety;
• The tire tread wears unevenly, and the service life of the tires is noticeably reduced;
• A hernia may appear on the wheel, and under high pressure when hitting an obstacle, the rubber may rupture, which is completely unsafe at high speed.

Below are three pictures that show how the rubber tread adheres to the road at optimal, low and excess pressure.

Many car owners are wondering what pressure should be in R14 tires on VAZ models. According to technical conditions, the wheels on a VAZ 2114 (2115) car are inflated to 1.9 kgf/cm² (R13), on VAZ 2110-2112 cars it is recommended 2.0 kgf/cm² (R14). Moreover, it makes no difference what axle the wheels are on - front or rear.

Optimal tire inflation for various situations

In this section we will talk about what pressure should be in the tires of a VAZ 2114 passenger car with a 14 radius in the summer and why. This information applies to wheels of other sizes, taking into account that the larger the rim diameter, the more the tire needs to be inflated. Increasing the size by 1 inch (instead of R13, put R140), increases the requirement for air compression inside the tire by 0.1–0.2 atm.

In summer on a dry asphalt road

To drive on a dry asphalt road and air temperature above +10 degrees and a standard load (5 people, each weighing 70 kg and 50 kg of cargo), the tires of a VAZ 2114 13 radius passenger car in summer should have a pressure of 2–2.2 atm in the front and 2 ,2–2.4 atm at the rear.

If you plan to drive with minimal load, then the tires of a VAZ 2110 passenger car with a 14 radius in summer should have a pressure of 2 atm in the front and 1.9 atm in the rear. Sometimes such vehicles are used to transport heavy materials, several hundred kg exceeding the official carrying capacity of the vehicle.

If you have to do this, inflate the wheels 0.1–0.2 atm more, and there should be more air in the rear axle tires than in the front wheels.

Summer on a wet road

A wet road is much more dangerous than a dry one, not only because of less grip on the wheel, but also because of the difference in water level, from slight humidity to depths of more than 1 mm. When driving through a puddle, even of this depth, there is a high probability of aquaplaning, when water lifts the tire above the road and completely deprives it of traction.

Any time of year on a dirt road

The main difference between dirt and asphalt roads is that the first does not have a flat surface, therefore, to drive on it, the pressure in the tires of a VAZ 2110 and other models must be approximately 0.5 atm lower than for asphalt.

INFLUENCE OF WEATHER CONDITIONS AND ROAD FACTORS

The pressure in VAZ tires in summer should, in principle, be the same as in winter. But in practice in winter it is made a little lower for a number of reasons:

• Slightly lower tires allow you to better control the car on slippery roads, it becomes more stable;
• The suspension is made softer, and road unevenness is less felt;
• The braking distance becomes shorter, reducing the likelihood of an emergency.

It is necessary to take into account the fact that after a temperature change (after leaving a warm garage on a frosty street), the pressure in the R14 tires will become less due to physical factors. Therefore, you should check it before you hit the road and, if necessary, pump up the tires. Also, when it gets warmer after winter, pressure measurements should be taken.

The pressure in R13 tires in summer is usually maintained at 1.9 atm, but this level is designed for an average vehicle load (two or three people in the cabin). If the car is fully loaded, then the pressure should be increased on the front axle to 2.0-2.1 atm., on the rear axle to 2.3-2.4 atm. The spare wheel is inflated to 2.3 atm.

Russian roads are not of good quality, and therefore many car owners deliberately lower the tire pressure somewhat so that all the unevenness of the road surface is not so noticeably felt when driving. Typically, in summer the wheels are lowered by 5-10%, and in winter by 10-15% of the norm. On flat roads you can stick to the factory standard.

Review of the best summer and winter tires

Using tires that suit the seasons will save fuel and make driving more comfortable. The best choice for summer driving would be the Toyo Nano Energy 3. This version of the wheel is characterized by a relatively low noise level and fuel efficiency. However, on wet roads the braking distance is relatively long.

Yokohama Bluearth AE01 will cost relatively inexpensively - about 3 thousand rubles for 1 cylinder. In this case, the composition of the mixture includes rubber and some other components that make the rubber soft.

Michelin Energy XM2 tires are one of the most economical and durable modifications. They are distinguished by their durable sidewall and excellent grip properties. The manufacturer provides a 5-year warranty. Like the model discussed above, handling on wet roads leaves much to be desired.

Nokian Hakka Green 2 tires, thanks to their unique tread design, provide driving comfort and save fuel. The manufacturer provides a lifetime warranty for this model.

Continental ContiEcoContact 3 was specially developed by the manufacturer for compact cars. The use of such tires will significantly reduce the braking distance, regardless of the type of road surface. The tire contains silicon dioxide. It provides excellent grip on the road.

Nokian Hakkapeliitta R2 SUV is a relatively expensive tire for driving in winter. The aggressive symmetrical pattern and a large number of slats make the machine as stable as possible. The cost of 1 cylinder is from 6 thousand rubles.

Nexen Winguard winSpike SUV WS6 175/65 R14C are tires manufactured in South Korea equipped with 250 steel studs. Easily support up to 600 kg per wheel. Cost – from 4,000 per 1 piece.

Sailun Endure WSL1 175/65 R14C is perfectly balanced and removes water well from the contact patch with the road. However, it is worth noting the absence of spikes - this point does not have the best effect on handling in winter.

GT Radial Icepro 3 175/65 can easily withstand loads of up to 530 kg per wheel. Speed ​​index T – up to 190 km/h. Reliable tires at a relatively low cost.

Roadstone Eurovis Alpine WH1 185/60 – non-studded winter tires. Designed for travel speeds up to 190 km/h. The cost is only 2,800 rubles. Which is an excellent solution for car owners on a limited budget.

Properly selected tires are the key to safe movement on the road. Nominal pressure and properly selected wheels ensure safety on the road.

LARGER DIAMETER WHEELS

From the factory, the installation of wheels with diameters R15 and R16 is not provided, but some car enthusiasts, in pursuit of fashion and improved technical characteristics, install them on their VAZs. And accordingly, you need to know what the pressure should be in the R15 tires, and what the pressure should be in the R16 tires. It all depends on the workload of the VAZ model. With an average vehicle load, the wheels are inflated to 2 kgf/cm²; on a loaded car, it is better to inflate them to 2.2 kgf/cm². And if there is a lot of heavy luggage in the trunk, then the rear tires are pumped up by another 0.2 kgf/cm². It turns out that the pressure in R14 tires is approximately the same as the pressure in R15 and R16 tires (for VAZ 2110-2115 models).

What determines wheel inflation/pressure in R13 winter tires?

The difference in the degree of tire inflation depends on the basic parameters of the car:

1. Gross vehicle weight with or without loading. With a loaded car, the wheels are pushed through more than with an empty trunk and driver.
2. Cylinder dimensions. Tire cavity capacity is of primary importance. For example, the pressure in winter tires R13 VAZ 2106 and R 16 on Vesta will differ by an average of 0.4 BAR.
3. Speed ​​index. At high speeds and driving on smooth asphalt, an improved free run is required. At the same time, for off-road modifications – this is not necessary.

METHODS OF MEASUREMENT

How to measure the tire pressure of VAZ cars? The measurement can be made using a special dial pressure gauge, but it should be noted that they may have an error of 0.2 atm. The pressure gauge can be either a separate device or as part of a wheel inflation pump.

We measure the pressure very simply:

1. Reset the pressure gauge readings to zero;
2. Remove the cap from the wheel spool (if there is one);
3. Place the pressure gauge fitting on the nipple and press;
4. We look at the arrow reading on the device.

It is recommended to take measurements at least once a month if the machine is used regularly. It is recommended to check tire inflation before leaving the garage after a long stay.

Pressure may increase when tires heat up. This often happens if the driver prefers a dynamic driving style with frequent and sharp braking. Therefore, measurements are taken on the car before the trip, when the wheels have not yet warmed up.

TIRES INJECTION WITH NITROGEN

Recently, it has become fashionable to inflate wheels not just with air, but with nitrogen.

There is an opinion that:

• Nitrogen keeps pressure more stable, and when the wheel heats up, it does not change in the tires;
• Rubber does not age longer because the pumped air with nitrogen is cleaner;
• A steel wheel rim rusts less;
• The likelihood of rubber rupture is reduced, since nitrogen does not support combustion and reduces the risk of explosion.

But it seems that all the claims about nitrogen are just a publicity stunt. The air is already almost 80% nitrogen, and if its content inside the tire increases to 95%, little will change for the better.

Therefore, it is hardly worth giving in to the persuasion of sellers of dubious services and throwing money away. The only thing you can be sure of is that the wheels will not get worse from pumping nitrogen. If you don't mind the money, then you can try this innovation on your car.

What are the benefits of pumping nitrogen into tires?

Nitrogen in the tires of the VAZ 2114, like any other car, according to tire fitters offering this service, has many useful properties. They claim that this gas:

• Makes blood pressure stable and constant;
• Increases rubber service life;
• Reduces the risk of tire rupture;
• Reduces the likelihood of disc corrosion.

But in fact, all these advantages are ordinary advertising. Injecting nitrogen costs a lot of money. Therefore, it is often recommended in tire shops. But in reality, it doesn’t matter what you pump into the wheels – nitrogen or air. And there is no need to overpay for more expensive gas.

What should the tire pressure be?

The manufacturer of both the car and the tires always recommends maintaining a certain tire pressure, and the tire pressure on both the front and rear axles does not necessarily have to be the same. It all depends on the load on the car, weight distribution, and weather conditions.

If the wheel has high pressure, then:

1. The resistance coefficient decreases.
2. Less susceptible to deformation.
3. The point of contact with the road is reduced.
4. Low shock absorption.
5. High controllability.

If the tire has low pressure:

1. The point of contact with the road increases.
2. The resistance coefficient increases.
3. Consumption increases.
4. More comfort on uneven roads.
5. Low controllability.

The tire consists of 2 main parts: Tread and sidewall. The protector is a dense material that is not very susceptible to deformation. The sidewall, on the contrary, suffers greatly from both low and high pressure.

At low pressure, it is possible that the rim of the disk will cut through the tire on a bump or hole, and you, at best, will not be able to continue driving on such a “wheel.” And with high pressure, upon impact, a hernia may pop out or simply burst. But we are talking about pressure 2 to 3 times higher than normal; if you overinflated the tire by 10-15%, then there is nothing catastrophic about it.

When you need to lower your tires a little

In some cases, there are recommendations to slightly lower the tire pressure than specified in the recommendations. There are two such cases:

1. In winter, if the pressure is a little less, then better traction occurs. But as the temperature changes, the internal volume in the tire also changes.
2. The most popular use for slightly lowered wheels is off-road driving. In this case, the wheels will act on the principle of tracks. Which will increase cross-country ability.

But it is difficult for an inexperienced driver to determine by what indicators to reduce the pressure. Therefore, we do not recommend experimenting.

Conclusion: the pressure in car tires must be checked regularly, maintained at the level recommended by the manufacturer, and weather and road conditions taken into account. This will extend their life and help make your ride safer.

Many owners of VAZ 2114 cars ask the question: “what pressure should be in the tires?” According to the manufacturer's recommendation, this indicator must correspond to a certain value. At the same time, on a VAZ 2114 car, the pressure in the tires of the front and rear axles may not be the same. This depends on the weight distribution, the load on the machine and the climatic conditions. If the pressure in the VAZ 2114 tires is higher than the nominal value, then they are less deformed, the drag coefficient and the point of contact with the road surface are reduced, high controllability and low shock absorption are observed. If the indicator in the wheel is low, then contact with the road and the drag coefficient increase, consumption increases, low controllability is observed, but greater comfort on uneven surfaces. The tire consists of a sidewall and tread. The protector is made of dense matter, which is little subject to deformation. And the sidewall suffers due to exceeding or decreasing this indicator. For example, in low pressure conditions on a hole or bump, the disc rim can cut the tire, and if it is exceeded, the wheel can burst or herniate. But if the tire was overinflated by 10-15%, exceeding the standard by 2-3 times, then a disaster will not occur. Many people ask the question: what pressure should be in the tires of a VAZ 2114 with a radius of r13. The car manufacturer advises setting its level around 1.9 kgf/cm², but you can set it to 2 kgf/cm². To accurately determine this indicator, you can use the formula in the table. For tires with a radius of r14 and r15, it is recommended to set about 2 kgf/cm². To determine exactly what tire pressure should be, the formula in the table is also used. Setting the parameter in tires does not depend on their size and radius, it depends on the load. Therefore, it will be approximately the same for all tire radii.

What should be the air pressure in the tires?

r13

The VAZ manufacturer recommends setting the tire pressure at 1.9 (kgf/cm2). You can also set it to 2 (kgf/cm2). For a more accurate determination of pressure, look at the formula in the table.

r14

The manufacturer recommends setting the pressure at 2 (kgf/cm2). For a more accurate determination of pressure, look at the formula in the table.

r15

Setting tire pressure does not depend on the radius and size of the tire, but depends on the load. Therefore, the values ​​for all radii are approximately the same. The manufacturer recommends setting the pressure at 2 (kgf/cm2).

For a more accurate determination of pressure, look at the formula in the table.

How important is it to maintain normal blood pressure?

Ensuring optimal vehicle stability on the road is the main task of tires. The safety of the driver and passengers depends on the stability of the vehicle on the road surface. At the optimal pressure level at the point of contact of the tire with the road surface, the load is distributed evenly. Hence all the ensuing consequences - adequate consumption, uniform tire wear, good handling.

It is necessary to measure the parameter on cold tires in the garage just before leaving. You can measure tire pressure using a special device - a pressure gauge.

R13 tires are most often installed on the VAZ-2114 car. This is considered a kind of standard. Although, the car can be equipped with wheels with a radius from R13 to R16.

How and how to measure tire pressure?

There are two main ways to measure tire pressure:

• Using a pressure gauge.
• Using a pump with a pressure gauge.

In both cases you need to do the same operations:

1. Remove the cap (if equipped).
2. Remove the cap or spool on the nipple.
3. Release the pressure on the pressure gauge using the button.
4. Place the pressure gauge or pump onto the nipple.
5. Let's look at the readings.

Each pressure gauge has an error of 0.2 bar.

What pressure should be in tires R13 R14 R15 in winter and summer

Not every driver pays attention to the pressure in the tires of his car. But safety on the road, controllability and maneuvering of the car sometimes depend on the pressure in the tires. In addition, the level of tire pressure affects:

• on fuel consumption,
• uniform wear of the wheel itself,
• may cause hernias on the wheel court.

If the pressure in tires r13 and r14 is increased, then, for example, when hitting an obstacle, the tire may even explode. Incorrect tire pressure r15 will also affect maneuverability when cornering, turning, etc. The following figure will best show the different levels of inflation of car wheels.

Tire pressure

As you can see, just by the wear of the tread you can determine what the problem is with inflating the rim, but it is better not to let it get to that point, but to maintain a certain atmosphere at the required values.

Tire pressure must be checked at least once a month. Professional drivers check every 2 weeks and before each long trip. And an external inspection of the wheels should be done daily before starting the car engine. Although if you are the happy owner of low-profile tires, then it is impossible to determine what pressure should be in the tires by eye.

Which wheels to choose: with or without a tube?

In recent years, tire fitting and car repair specialists have been advising the purchase of tubeless wheels. But just a decade ago it seemed fantastic. Today, the use of tires with tubes is a rare occurrence, and in a couple of years, wheels with a tube inside will probably only be found on bicycles.

A tubeless tire has better wear-resistant characteristics due to increased vulcanization. Due to their lighter weight, their technical characteristics are better due to lower inertia. In addition, a tubeless tire balances better. Their service life is also longer. In addition, in the event of a puncture, the tubeless tube will hold air longer, which will allow you to safely get to the service center.

Also, we will not consider the issue of driving in winter on winter tires with studs and greater tread depth, because... this affects your safety and the safety of not only the car, but the life and health of others. Therefore, in the summer we use summer wheels and no “all-season” tires during other periods, unless you live in snowless Europe. The choice of tire manufacturer brand is your choice; the only thing worth paying attention to is that the radius of the wheels must exactly match that recommended in the vehicle’s service book.

What tire pressure should be?

You don’t need to be a professional to answer the question: “How to measure tire pressure?” The pressure in car tires is measured with pressure gauges, which can be dial, mechanical and digital (electronic). For the best result, it is necessary to measure on a cold car, before driving, because... During operation, the wheels heat up, and therefore the pressure increases. You need to measure all four wheels with a pressure gauge, because... pressure can be different everywhere. Very often, the pressure gauge function is installed in pumps (compressors) for inflating car tires. Compressors are connected either to the car's cigarette lighter or to the battery terminals.

Tire pressure is indicated in atmospheres. The atmosphere is the value of kilogram per square meter. Typically, recommendations on what pressure in the tires of a car should be indicated in the car’s service book. Also, recommended atmospheric pressure values ​​can be placed on a sticker located either on the gas filler door or on the pillar next to the driver.

Tire pressure table for VAZ car

If you do not find the recommended parameters, then it is better to call any dealership of your car brand. There are no alternatives to the values ​​defined by the manufacturer, so the specified values ​​must be adhered to. There are recommendations on the tires themselves, but they are not relevant, because... A certain brand of wheels can be installed on different cars.

How much should the tire pressure be for r14 tires? It is generally accepted that the pressure in r14 tires or tires of any other radius should be within 2-2.2 atmospheres. And at full load up to 2.4. But this is not entirely correct. Each car has a different weight. Yes, and the radius of the wheels may vary; in addition, the recommended pressure density is influenced by weather conditions and the road surface. They also make different settings for tire pressure on the front and rear axles of the car. It depends on the type of drive wheels.

When you determine the required tire density range, it is better to inflate to its minimum value, because... at this level, the grip of the wheels on the road will be maximum, therefore, it will be easier to drive the car.

Features of tire inflation in winter and summer

As mentioned above, you need to check the density of tires on a cold car. It is also better to inflate tires, especially in winter, not immediately after using the car, but when the wheels “cool down” a little. This rule applies to both winter and summer maintenance. In winter, we measure the pressure and pump up the tires no earlier than 2 hours after stopping. In summer, due to the high ambient temperature, cooling occurs much more slowly, this should also be taken into account. In winter, the ideal option would be to inflate tires in a warm box or tire shop; this will help to avoid differences in pressure, and in this case the indicators will be close to ideal.

Please note that if the car is fully loaded, the pressure in the tires will increase significantly, this should also be taken into account. Significant changes will also occur when the ambient temperature fluctuates greatly. Therefore, when the weather changes, you need to measure the tire pressure more often.
