VAZ cars can be considered one of the most famous brands in the post-Soviet space. Today you can find both the old VAZ-2106 and the 2107 models. Samara 2109 and 21099 are quite common. Fans of the domestic auto industry today are purchasing more modern models: VAZ 2110, 2112, 2114 and 2115. This suggests that even with the appearance on the market of a large number of affordable foreign cars, the cars of the Volga plant have not ceased to be in demand among motorists.
It is important to always know the pressure in the tires of the car In order for the service life of the car to be long enough, it is necessary to strictly adhere to all conditions correct operation. Among the various factors that determine the proper use of the machine, tire pressure is very important and significant.
Car tire pressure, how important is it?
However, we should not forget that it also depends on the load distribution, ambient temperature and other factors.
Control measurement of pressure in the tire of a VAZ 2106 car With pumped wheels, we observe the following:
- reduction of the drag coefficient;
- lower degree of deformation;
- smaller contact patch with the road;
- reduced shock absorption;
- increased manageability.
With underinflated wheels, the following phenomena are observed:
- increase in the size of the contact patch with the road;
- increase in drag coefficient;
- increase in fuel consumption;
- increase in smoothness of the course;
- deterioration in vehicle control.

How does the type of rubber affect the amount of pressure?
You should know that the tire diameter does not affect the pressure indicators - for r13, r14 and r15 rubber it will be the same. Here the degree of load on the wheels plays a role.
Keep in mind that when there is a temperature difference, for example, if you leave a warm place in a cold place, the pressure in the tires may become lower. In summer, they should have about 1.9 atmospheres with an average load. If the car is fully loaded, the rubber should be pumped up to 2.1 atmospheres.
Tire pressure table for different VAZ car models
The table below shows what tire pressure should be for various models of VAZ cars. We provide an incomplete list, older types, like VAZ-21099, and newer cars: VAZ-2110, 21111 and 21112.
Table of recommended tire pressure for VAZ cars In winter, it is customary to lower the wheels a little, although it is officially stated that the degree of their pumping does not depend on the season. However, lowered tires provide the following benefits:
- better stability on slippery roads;
- smooth running of the car;
- reducing the braking distance and reducing the likelihood of an emergency.
Check your car's tire pressure regularly
Owners of VAZ cars, like any other brands, are advised to regularly check the degree of inflation of the wheels - at least once a month. Practice shows that during the month the pressure decreases by 0.4 atmospheres. In this case, it is necessary to pump up the wheels.
To measure, it is not necessary to constantly travel to a service station - you can do it yourself with a pressure gauge. We do it this way:
- We reset the instrument readings.
- We remove the cover from the spool.
- We put the fitting of the device on the nipple and press.
- We take readings of the device.
Check your car's tire pressure regularly Since the temperature can significantly affect the readings, it is necessary to take them before leaving the garage on "cold" rubber. Remember that regular inspection is a guarantee of your safety and a long service life of the vehicle.
Conclusion
For many years, VAZ brand cars have remained the most famous and popular variety of products of the domestic auto industry among consumers. They are not considered as prestigious as in the old days, but they honestly serve faithfully for several generations of motorists.
One of the important factors that determines the literacy of the operation of a car is tire pressure. The manufacturer insists that the owner of the car is obliged to ensure its value recommended in special tables. This affects factors such as vehicle handling, fuel consumption, ride comfort and driver and passenger safety.
Foot pump with manometer NNU-500 Tire pressure depends on the model of the car, the type of rubber and the load index. Referring to the tabular data, each driver can determine the optimal value for his car.
Regular monitoring of indicators is also a prerequisite for the proper operation of the car, its long service life, as well as your safety on the road.
1 commentMore - less (deviation in tire pressure)
Our interest in tire pressure is by no means idle. Its applied component is the connection with fuel consumption. Do we lose rubles and how much, deviating "down" by 0.5 atm from the recommended pressure, and do we win by pumping the tire? What are the implications of eye pressure control? After all, a deviation in one direction or another by half an atmosphere is almost impossible to visually detect. And are those who intentionally depressurize their tires to improve their ride, or pump them up to save gas, right?
And one more thing: if the effect of pressure on rolling resistance is significant, can this dependence be used for good? And at the same time we will find out how the change in tire pressure affects other qualities of the car.
These are, in fact, the tasks for which we once again took up the car, tires and measuring equipment. The car is a Lada-112 on Kleber Viaxer tires with a dimension of 175/70R13. The load is the driver and operator of the Vbox measuring complex.
NORM
We start with a base pressure of 2.0 atm, taking it as a starting point. We warm up the tires with a ten-kilometer run, accelerate and measure the run-out from a speed of 80 km / h. It turns out 1175 meters - by no means an outstanding result for the Lada-112, but we are interested not so much in the value itself, but in its deviations with pressure changes. The same applies to the top speed at the "rearrangement" - we got 65.9 km / h. The next objective test: the length of the braking distance on the verge of blocking the wheels. On dry pavement, the car stops exactly after 46 meters.
Let's move on to the assessments: handling, directional stability, ride smoothness - all parameters did not cause any complaints or special enthusiasm. Therefore, the scores in each exercise are “norm”, that is, 8 points.
MINUS
We give the car to settle so that the temperature in the tires drops to the initial one, and we release the pressure to 1.5 atm. The first differences in the behavior of the car are already noticeable during the heating of the tires - the road seems to have become smoother, and the cracks on it have diminished. No, of course, the tires just became softer, which had a positive effect on the smoothness of the ride. But the directional stability on the straight line worsened: the car began to walk along the lane, reacting to the slightest lateral disturbance - be it a road bump, a slight side slope or a light gust of wind. Estimates of 9 and 7 points, respectively.
The run-out was reduced to 1108 meters - we “lost” almost 70 meters (5.7 percent). At the same time, consumption increased slightly, only about 2 percent.
On the "rearrangement" the speed slightly decreased. The reason, I think, is clear - the handling has deteriorated. It has become much more difficult to get into the second corridor of the “rearrangement” - the car strives to jump to the right or left. Score no more than 6 points.
But braking distances decreased - they won back more than a meter from the "normal pressure". The decrease in pressure caused an increase in the contact patch, and most of the micro-roughnesses of the road relief entered into braking work. Braking control has also become more pleasant: in this case, it is easier to dose the force on the pedals (to control the initial phase of wheel blocking). Yes, and the results of measurements of braking "lay down more closely."
A PLUS
Before the final stage - a short break. While the tires are cooling, we raise the pressure to 2.5 atm.
The road is well known, directional stability is very close to the original state (8 points), but the smoothness of the ride has become worse - it seems as if all the road patches and small seams are swollen, and the pumped tires, clapping on them, vigorously shake the car. Write down 6 points.
The run-out is 1232 m - the difference with the previous state is more than 200 meters, and with the initial one - 52 m or 4.9 percent. The effect is slightly less than when the pressure is reduced by the same 0.5 atm. And only 1.6 percent of gasoline can be saved.
But on the “rearrangement” the speed is record - almost 67 km / h. But there are comments on handling - in comparison with the norm, the feeling of the steering wheel has noticeably worsened. The pumped-over tires have practically lost their pulls, and this, oddly enough, harms the “understanding” of the car, especially in critical modes. No more than 7 points.
The braking distance has not changed much - only the spread of results has increased slightly, but it has become more difficult to stay on the verge of skidding. We put seven for the convenience of braking control.
CALCULATOR
And now let's calculate what we are given games with pressure. We focus on the average fuel consumption of 8 l / 100 km and the price of gasoline 18.5 rubles / l AI-95. With reduced pressure, fuel consumption increases by 2 percent, that is, it will increase to 8.16 l / 100 km. In monetary terms, it turns out 29.6 rubles per 1000 km. A vacation trip of 4,000 km will receive an addition of 118.4 rubles. - the figure is not at all impressive.
Now let's weigh the savings from tire "hypertension" - 8 liters minus 1.6 percent give 2.4 rubles per 100 km - for the same vacation you will be able to "get rich" by 94 rubles. Even if we add up the “winned” money with possible losses, we will get a very modest economic effect - 214 rubles.
But a decrease in pressure by half an atmosphere below the recommended one, in addition to increasing fuel consumption, worsens controllability and exchange rate stability. Although there is some benefit - the "brakes" become a little better, the smoothness of the ride increases.
Tires inflated to the same "half point" allow you to win back almost one and a half percent of the fuel and increase the speed of extreme maneuvers by 1 km / h. True, at the cost of reduced ride and some deterioration in handling.

MORE? LESS? NORM!
The conclusions, frankly, are unexpected - the deviation of tire pressure in one direction or another does not so much affect rolling resistance (read, fuel consumption), but destroys the balance consumer qualities car! In addition, at any abnormal pressure, the protector wears out unevenly. In flat tires, the edges are more intensively squeezed - the shoulder zone, and in pumped tires - the middle part of the tread. It turns out that the tires should be maintained at the pressure recommended by the car manufacturer. And yet, the deviation "down" is fraught with more unpleasant consequences than the "up".
To check the wheels on a Lada Priora VAZ 2170 car, you will need: a pressure gauge, a pump, a caliper.RECOMMENDATIONS
Check tire pressure periodically. High or low pressure leads to premature tire wear, poor handling and stability of the car Lada Priora. We recommend using a foot pump with a built-in pressure gauge. In order for the tires to wear evenly, every 15,000 km (at the next maintenance) rearrange the wheels in accordance with the diagram in fig. 4.1. After the first 15,000 km and then every 30,000 km, balance the wheels and check the wheel alignment. To do this, contact a specialized tire shop.

WARNINGS
Carry out all wheel repair work in specialized tire shops. Check that all wheels are balanced after repair.
Operating tires with worn tread may lead to an accident.
1. Unscrew the cap from the valve on the wheel.
2. Check tire pressure. To do this, reset the pressure gauge to zero by pressing the special button on the pressure gauge housing... 
3. ... connect a pressure gauge to the valve and press it with the tip of the pressure gauge.
Lada Priora is the most popular family today domestic cars. The model is produced in the body "hatchback", "sedan" and "station wagon" and belongs to the class "C".
The main competitors are budget 4-doors: Renault Logan, ZAZ Chance, Lada Granta and Daewoo Nexia. Lada Priora boasts excellent noise and sound insulation, high-quality finishes and adaptation to Russian conditions. In comparison with "classmates" it is more maintainable, and spare parts for it are cheaper. There is a domestic product and disadvantages. The operation of the model's engine is not always stable, it is sometimes difficult to start it due to problems with the timing, air leakage and sensors. Also, the components for the car are not of high quality.
Despite this, Lada Priora remains one of the most popular cars. Russian market. In the Caucasian regions, it confidently holds the lead in terms of sales. Also, the car is in the top 5 most stolen models of the country.
Lada Priora is updated version popular model"VAZ 2110", the production of which was completed in 2007. Over 1,000 changes have been made to the design of the "ten" that has become beloved by many Russians. As a result, a new family of cars appeared, consisting of 3 representatives:
- "VAZ-2170" - a sedan, the release of which began in March 2007;
- "VAZ-2172" - a hatchback that appeared in February 2008;
- "VAZ-2171" is a station wagon, sales of which began in May 2009.
After the modernization of the "VAZ-2110" appeared fundamentally new car retaining its former features. In the first version of Lada Priora, similarities with the "ten" were clearly visible, but the nose and stern of the car became different. The headlights have grown in size, and the grille has become larger. The taillights were also finalized, but in general, changes in appearance could not be called global.
If the exterior of the model is the development of the specialists of the Volga plant, then the interior was created by the designers of the Italian company Carcerano. As a result, he was strikingly different from what he was in the top ten. The front panel looked more like a "torpedo" foreign car. It was trimmed with soft plastic, adding a curved visor above the instrument cluster. The interior was complemented by an oval-shaped clock set in a silver trim at the top of the console.
The basic equipment of Lada Priora has become noticeably richer. It offered electric front windows, central locking with a remote control, athermal windows, an airbag, electric power steering, an electronic clock and an adjustable steering column.
The car was available in three trim levels: "Standard", "Norma" and "Lux". They differed only in the level of equipment. The model was equipped with 2 types of gasoline units:
- 1.6-liter 8-valve VAZ-21116 engine (90 hp);
- 1.6-liter 16-valve VAZ-21126 engine (98 hp).
Wheel size
A small selection of versions of the Lada Priora model also limited the types of wheels available for use:
- rims 5.5J on 14 ET37 (5.5 - width in inches, 14 - diameter in inches, 37 - positive offset in mm), tires - 185 / 65R14 (185 - tire width in mm, 65 - profile height in%, 14 - rim diameter in inches);
Other wheel specifications and tire pressure:
- PCD (drilling) - 4 by 98 (4 is the number of holes, 98 is the diameter of the circle on which they are located in mm);
- fasteners - M12 by 1.25 (12 - stud diameter in mm, 1.25 - thread size);
- diameter central hole- 58.6 mm;
- tire pressure - 1.9 bar.
Generation 2
In 2013, Lada Priora was updated. You should not look for striking transformations in the appearance of the model, but new touches and details have appeared here. After restyling, the model received headlights with daytime running lights, brake lights and taillights with LEDs. The radiator grille instead of a rectangular shape was made pentagonal with a honeycomb cladding structure. rear bumper received an energy-absorbing insert and a new design. At the same time, the dimensions of the model remained the same.
Changes in the interior turned out to be much more. Inside the restyled Lada Priora, new finishing materials and modified seats have appeared, the architecture of the front panel has changed. At the top of the center console installed a color display with touch controls. The seat backs have increased by 40 mm, which has a positive effect on comfort. The interior of the updated Lada Priora has become quieter.
In addition to design changes, the technical part. The model has got an improved suspension and a new steering with less gear ratio. The main difference was the advanced 1.6-liter unit with dynamic supercharging with a capacity of 106 hp. Former power plants remained available. The configurations have not changed either. Lada Priora was still offered in the Standard, Norma and Lux versions with the following types of wheels and tires:
- 5.5J wheels for 14 ET37, tires - 175 / 65R14;
- 5.5J wheels on 14 ET37, tires - 185 / 65R14;
- 5.5J wheels on 14 ET37, tires - 185 / 60R14;
- 6J wheels on 14 ET35, tires - 195 / 60R14;
- 6.5J wheels for 15 ET35, tires - 185 / 55R15;
- 6.5J wheels for 15 ET35, tires - 195 / 55R15;
- wheels 6.5J on 16 ET35, tires - 195 / 50R16.
The body of the model was made of low-alloy steel and galvanized metal, which made it possible to extend the warranty against corrosion up to 6 years.
About what pressure should be on the car "Lada Kalina", "Grant" or any other model of this Russian manufacturer, there are disputes among motorists. Some look at the passport and inflate tires in accordance with the standard values, others try several options for tire pressure.
We can definitely say that the pressure in the Grants, Kalina or Priory tires affects undercarriage, affects fuel consumption, and also contributes to or prevents rapid tire wear.
Normative tire pressures There are 3 options for the state of wheel pressure in the Lada:
- understated. There is an increase in the contact of the surface of the wheel "Grants", "Priors" or "Kalina" with pavement which speeds up wear. Fuel is consumed faster, and the braking distance increases;
- overpriced. The wheels of the car are less in contact with the road surface, which increases the likelihood of an early repair of the chassis. Wheel wear also increases. At the same time, the vehicle's handling at high speed deteriorates or sharp turns. Passengers and the driver feel that car rides are becoming less comfortable - the car bounces even on small potholes;
- normal. By such pressure is meant an indicator that is in the range of 5-15% of what is indicated on the car or in the passport. In this case, the tires wear evenly. Being in the car while driving on uneven road surfaces or off-road is comfortable.
Wheel inflation features
To ensure comfort and safe driving"Kalina" in winter and summer, it is necessary to measure the degree of inflation of the wheels with a mechanical or electronic pressure gauge.
Permissible air pressure in the tires of Lada Priora cars You will also see the optimal inflation mode in the table given by each tire manufacturer. The values in it are adjusted depending on:
- number of passengers, luggage;
- car models (indicators of "Grants", "Priors" and other models of "Lada" differ depending on their weight).
Remember that the same pressure must be maintained both in winter and in summer.
Recommended tire pressure for Lada Granta cars However, there is a caveat: if the Lada Kalina has been standing for a long time in a warm garage or at a service station, get ready for a slight decrease in wheel inflation after driving out into the cold.
Thus, you will have to pump up the tires of your car more often in the cold season.
The standard value of the pressure indicator in the front and rear wheels for "Lada Kalina" should be like this:
- for the VAZ-1117 model - 1.9 atm on the front and rear wheels at partial load, as well as 1.9 / 2.1 on the front and rear wheels at full load;
- for the VAZ-1118 model - 1.9 or 2 atm at partial load, as well as from 1.9 to 2.2 atm at full load on the front and rear wheels, respectively;
- for the VAZ-1119 model - 2 atm at partial and 2 / 2.2 atm at full load on the front and rear wheels, respectively.
Permissible air pressure in Lada-Kalina tires Partial loading of "Priors", "Grants" or another Lada model, experts call being in the car up to 3 people, provided that the trunk is not loaded. Full load - the maximum possible number of passengers in the car and cargo in the trunk (with a weight of less than 50 kg).
If you want to know the tire inflation figures, wait for the wheels to cool down (after a long drive or exposure to the sun). This will make the pressure gauge results more accurate.
