Mistakes when checking tire pressure

Any experienced motorist knows that tire pressure should be checked at least from time to time. Even better to do it on a regular basis, so as not to miss the moment when the pressure is at an unacceptable for the car. At that, as practice shows, the overwhelming majority of motorists, one way or another, make the same mistakes while checking the pressure.

The car tire pressure parameter is influenced by factors such as wheel diameter, tire type, road surface, driving style and even the make of car. The easiest way to check the pressure is to use a pressure gauge. It is not difficult to find out how much pressure should be in the tires of your particular car. To do this, just find a table with the corresponding parameters. It contains data on what the pressure should be when using tires of this or that size, as well as at this or that car load. In modern cars, the plate is attached by the manufacturers or in one of the doorways or on the gas tank hatch. It is important to remember and understand that the pressure in tires is a thing inconstant, which needs to be controlled and adjusted.

If the tire pressure is higher than normal, the wheel becomes too hard, which causes more vibrations penetrating into the cabin, increasing the risk of damage to the rubber, reducing the quality of traction with the road surface, greater suffering and uneven wear pattern on the tires, increased braking distance, reduced vehicle stability. If the tire pressure is lower than normal, it increases fuel consumption, accelerates tire wear, makes it harder to control the vehicle, and reduces vehicle stability on the road. A deviation of 0.5 bar is not considered critical. The deviation of 1-1.5 bars is considered dangerous. A pressure deviation of 2 bars increases the braking distance on wet roads by 10-12 meters, which is comparable to 2 widths of a crosswalk!

Worst of all, many motorists make two common mistakes when checking tire pressures. First, motorists often forget that tire pressure varies depending on the load of the car and the size of the wheels. For example, they measure the pressure in a car with two passengers and luggage. Having a partly loaded car, citizens look at the figures of normal pressure for the empty car, and then they understand the wrong decision to reduce the pressure in the tires! Secondly, many people measure the pressure “hot”, immediately after the car has been in motion. The right way to measure the pressure is strictly “cold”, when the car has been idle for at least 2-3 hours
