How to determine the tire pressure

The maximum load on the tires of the car, their condition and service life are directly dependent on the pressure that is maintained in the wheels. The optimum tire pressure is determined by the car manufacturer.

How to determine the tire pressure

You will need

  • - car wheels;
  • - a manometer;
  • - special caps;
  • - electronic system.

Instructions

1

Check the tire pressure in the vehicle two times.month. In addition, inflate the tires before each long trip. Be sure to inspect the tires before starting the machine. If visually the tire seems deflated, measure the pressure in it and, if necessary, pump it.

2

Do not treat pressure control lightly. The change in tire pressure by 0.5 kg / cm2 (0.5 bar) is not visually noticeable. In this case, the reduced pressure destroys the tire, and the increased pressure increases the load on the suspension. In both cases, the controllability of the car deteriorates and fuel consumption increases.

3

To determine the change in pressure in the tires on the behavior of the machine on the road, a lot of experience is needed. Therefore, determine the tire pressure with a good manometer.

4

Make sure that the pressure gauge is working properly andproduces the correct results. To do this, compare its readings with those that are obtained when measuring by specialists of a maintenance station or a tire fitting workshop.

5

Find out the optimum tire pressure for yourcar. It is written in the service book of the car or on the information sticker located on the door pillar from the driver's door, or on the fuel filler flap.

6

Please note that this is the recommended pressure incold bus. Therefore, and you need to check it before a long trip (intensive traffic significantly heats the tires) and not in the sun. The change in the ambient air temperature by 8 ° C corresponds to a change in the tire pressure by about 0.1 kg / cm2. As the temperature rises, the pressure increases, and when it decreases, it decreases.

7

Measure tire pressure with a pressure gauge. Place the pressure gauge perpendicular to the plane of the disc. Push it end onto the nipple so that it does not let in air.

8

Install on the bus valves instead of the usualspecial caps with color indicators. By changing their color, you will know that the pressure has changed. The downside of this method is that the caps only inform about the pressure drop to a certain value. So pick up the cap for your car.

Determine the dangerous pressure change in the tires using an electronic system, if it is installed in your car.
