Any modern passenger car or freight car can be serviced and repaired independently, in a regular garage. All that is required for this is a set of tools and a factory repair manual with a detailed (step-by-step) description of the operations. Such a manual should contain the types of applied operating fluids, oils and lubricants, and most importantly - the tightening torques of all threaded connections of parts of the vehicle components and assemblies. Italian cars - Fiat Alfa Romeo Lancia Ferrari Mazerati (Maserati) have their own design features. You can also join a special group select all french cars - Peugout (Peugeot), Renault (Renault) and Citroen (Citroen). German cars complex. This applies especially to Mercedes Benz ( Mercedes Benz), BMW (BMW), Audi (Audi) and Porsche (Porsch), in a slightly smaller - to Volkswagen (Volkswagen) and Opel (Opel). The next large group, isolated by design features, is made up of American manufacturers - Chrysler, Jeep, Plymouth, Dodge, Eagle, Chevrolet, GMC, Cadillac, Pontiac, Oldsmobile, Ford, Mercury, Lincoln . Of the Korean firms, it should be noted Hyundai / Kia, GM - DAT (Daewoo), SsangYong.

More recently, Japanese cars have been characterized by relatively low initial cost and affordable prices for spare parts, but recently they have caught up with prestigious European brands in these indicators. Moreover, this applies almost equally to all brands of cars from the land of the rising sun - Toyota (Toyota), Mitsubishi (Mitsubishi), Subaru (Subaru), Isuzu (Isuzu), Honda (Honda), Mazda (Mazda or, as they used to say, Matsuda) , Suzuki (Suzuki), Daihatsu (Daihatsu), Nissan (Nissan). Well, and the cars produced under the Japanese-American Lexus brands(Lexus), Scion (Scyon), Infinity (Infiniti),

Many car owners of the popular Japanese crossover Nissan Qashqai does not attach serious importance to one of the most important indicators that determine the clarity of its control on the roads. This is the tire pressure in the wheels, which differs not only from seasonality, but also from the radius of the tires. Often, on a car, a table with the necessary tire pressure data for the Nissan Qashqai is located on the pillar of the doorway or on the inside of the gas tank hatch. But if it is not there, you should familiarize yourself with the recommendations of experts below.

What should be the pressure in the wheels of the 16th radius

When monitoring pressure or inflating tires, it is worth considering that the old pressure gauges used by many motorists can significantly overestimate the readings due to excessive wear on the internal spring.

R16 wheels are the base in the Qashqai crossover and have the most successful characteristics for vehicle handling and suspension softness. The indicators recommended by the automaker are as follows:

• front tires of the car - 2.3 atmospheres;
• if the passengers back row there are less than 3 people in the car, the rear tires must be inflated to 2.1 atmospheres;
• if there are more than 3 passengers, then the rear wheels are pumped up to 2.3 atmospheres.

Inflated tires should be checked only after the car has been parked for a long time, when they are completely cool. When inflating tires to the values ​​recommended by the automaker, one should not forget about the properties of air, which in the hot season is subject to expansion, and in the frosty season tends to shrink.

It is for this reason that many experts recommend not to bring the pressure in the wheels to the recommended norm in summer, leaving about 0.2 atmospheres for air expansion, and in winter, on the contrary, strictly adhere to the norm.

How to inflate the wheels of the 17th radius

Non-standard tires installed on a car require more careful monitoring of tire inflation using modern electronic pressure gauges with a small error, this will help to avoid possible emergencies due to low or excessively high blood pressure.

The automaker provides for the complete set of the Qashqai crossover with R17 wheels, the pressure in which should be similar to that of 16-radius tires, namely:

• before - 2.3 atmospheres;
• rear with an unloaded car - 2.1 atmospheres;
• with more than 3 passengers - at least 2.3 atmospheres.

Due to the physical properties of air, which expands noticeably when heated, and when low temperatures begins to shrink, it is quite difficult to control and maintain the correct indicators. To facilitate the task, the automaker has provided a special system called the pressure regulator.

This system can be installed as a separate option on the Nissan Qashqai crossover and use it to inflate the car's wheels directly from the passenger compartment. For this purpose, the pressure regulator is equipped with air compressor and special valve taps, and its control panel is placed on the crossover dashboard.

Conclusion

Tire pressure is one of the important conditions for safe and comfortable driving modern cars, ignoring or ignorance of which can seriously affect the length of the operational life of the suspension units. That is why it is extremely important to correctly observe it and always inflate the wheels in a timely manner.

The correct tire pressure of any car is the key to a comfortable and safe ride. As practice shows, on average, tires lose up to 0.3 atmospheres per month of active use of the car. That is why it is very important to regularly measure tire pressure and fix any problems.

Pressure Measurement Methods

How can you correctly measure tire pressure in Nissan models such as Almera, Beetle, Qashqai or X-Trail? This should be done only with the help of special equipment - pressure gauges. Such devices for measuring tire pressure are suitable for almost all types of cars, including Almera, Qashqai, Beetle or X-Trail.

In total, there are 2 types of pressure gauges according to the mechanism of their work:

• mechanical (switch);
• electronic.

If you are interested in the most accurate device, you should pay attention to electronic pressure gauges. They can be used even in cold weather. With regard to accuracy, the possible deviation is no more than 0.05 bar.

Pressure measurement with an electronic pressure gauge

For pointer and mechanical pressure gauges, the percentage of deviation is slightly higher. But for home use, it is quite suitable. Especially since mechanical types pressure gauges are the most durable and resistant to mechanical damage and bad weather conditions. So for measuring the tire pressure of your Nissan Almera car, this is one of the best options.

But there is a simpler method: do not buy devices, but simply periodically conduct technical inspections and pressure measurements at the service station.

Getting the metrics right

Even if you purchase the most accurate device, a priori it will not give an accurate result if it is not used correctly. To measure the tire pressure of your Nissan Almera to be accurate. You need to take readings under the following conditions:

• tires must be unheated;
• machine - in a "cold" state;
• the pressure of all 4 wheels, including the spare one, is taken into account.

It should be noted that if the measurement is carried out in the cold season, it is better to use. It gives the most accurate results.

Measurement process

Measurement of pressure in the tires "Nissan X-Trail" is carried out as follows:

• on the pressure gauge, using a special button, the readings are reset;
• the cap is removed from the pressure gauge nozzle and the spool;
• a pressure gauge is immediately attached to the hole;
• tire readings are recorded.

If the device gave out more than necessary, the tires should be lowered. If less - download.

Please note: if the pressure readings in the X-Trail tires on the pressure gauge are always less than necessary, you need to check the condition of the spool and tighten it to the desired threshold. If this is repeated systematically, it is better to completely replace the part or contact the service station. Perhaps the problem is in the tire itself.

Pressure standards for Nissan

As a rule, such standards should be indicated on a special plate on the inside of the door from the driver, in the area of ​​\u200b\u200bthe gas tank or on inside trunk roof. If there is no such plate, you can find data on the Internet. In the latter case, they should be taken only as an approximate guideline.

There is also one very important detail to consider. In such tables, tire pressure is indicated only for the sizes recommended by the manufacturer. If you will use other tires, then install correct pressure only be obtained experimentally.

Table with standard tire pressure Nissan Almera

Please note that in the cold season, the pressure rate should be 0.3 bar less than indicated in the table. In other words, your Qashqai's tires should be slightly deflated. This is due to the fact that in this position a larger patch of adhesion to the road surface is provided. The more the tire sags, the more the Velcro opens on the rubber, which ensures good grip even on ice.

This is due to the fact that the load on the rear of the wheelbase is greater than on the front. This is especially true of the loaded Qashqai car.

Possible negative factors

• increased fuel consumption;
• deformation of tires, running gear;
• the possibility of the tire bursting.

In addition to the fact that such factors affect the operation and life of your vehicle, it's also unsafe. Therefore, such problems should not be neglected.

Agree, it is much more profitable to prevent a problem than to spend money on its repair later. So technical inspection of your vehicle should be carried out in a timely manner.

Is the most important thing drivers can do for their tires. In a period of just one month, a tire can lose up to 0.3-0.5 atmospheres of air pressure. It is important to check the air pressure regularly to make sure your Nissan tires are neither under-inflated nor over-inflated at the same time.

The worst enemy of a tire is too little pressure in them. It leads to increased tread wear on outer edges(or "shoulders") tires. It also generates excess heat, which reduces tire life. Finally, insufficient pressure increases fuel consumption by increasing rolling resistance ( soft tires for cars make it difficult to move freely).
