Optimum tire pressure - a guarantee of safe driving

Maneuverability, fuel consumption and driving safety determine not only the skill of the driver, the technical capabilities of the engine and the running gear, but also the pressure in the tires. The tires depend on the car's ability to "keep" the road, as well as your safety. Maintaining optimal pressure in the wheels is a guarantee of trouble-free driving on any road and in all weather conditions.

Manufacturers of cars in the operating instructions indicate the permissible pressure in the tires of the car, at which the vehicle should be used. These figures are due to the size of the tires installed on the car, and the car enthusiast must adhere to these parameters.

When should I check the tire pressure?

First of all, the pressure should be checked for sudden changes in temperature. In wheels with parameters 185/65/13, the optimum pressure is 2.0 atm at a temperature of 25 degrees Celsius. Lowering the air temperature by 10-20 degrees leads to a drop in pressure to 1.5-1.7 atm. The lowered pressure in the tires of the car increases fuel consumption by 15-30%, worsens the controllability of the car and accelerates the tire wear process . At the beginning of the seasonal temperature drop, when the thermometer during the day fixes the temperature from -5 to +5, it is already necessary to pay attention to the tire pressure and take measures to normalize it.

Secondly, the tire pressure is checked when the car loads. For example, when transporting a large number of passengers or goods whose weight exceeds the capabilities of the car. Recommended 2,0 atm (for the tire size 185/65/13) will turn into 2.8-3.0 atm. Such indicators will worsen the adhesion of the tread to the road surface, which will result in poor controllability of the car, increase fuel consumption and braking distance by 1.5 times, naturally, such pressure in the tires will shorten their service life.

Pressure control with option or pressure gauge

In the European Union, since 2012, cars with pressure sensors in tires (pressure gauges) have started to sell, and this is no longer an optional device, but functional and mandatory on all new cars. The mechanism tells the driver to change the pressure to a greater or lesser side. You can independently install such a sensor, informing you about the tire pressure indicators. This device is suitable for those who travel a long distance.

What is the tire pressure? Such a question should be set by any motorist before each trip. If you travel a short distance in a year, use inexpensive portable pneumatic or digital pressure gauges. With these devices, you can always check the tire pressure yourself.

In the car, each system requires constant monitoring by the driver. The pressure in the tires is not a trifle, ignoring the condition of the rubber leads to financial expenses for fuel and wheel repair, and can also cast doubt on the safety of driving in the car. Therefore, it is so important to systematically check and correct it.
