Check of pressure in tires

Constant control


  1. You will find the exact parameters of pressure operating for your car on a sticker in a folding cover of the fuel tank.
  2. The one who attaches significance to comfort supports pressure specified there in tires. But if you are ready to sacrifice the lowered comfort the movement for the sake of more sensitive steering, a little bigger service life of tires and slightly smaller consumption of gasoline, then increase air pressure in summer tires approximately on 0,2 bars.
  3. Zimin tires have to be pumped up always 0,2 bars more, than it is established for summer tires.
  4. The spare wheel has to be always pumped up up to the maximum pressure established for this car.

Air pressure in tires is checked in a cold state

Through several kilometers of a way pressure in tires increases by 0,2–0,4 bars. This increase in pressure because of heating of tires brings a mistake and therefore it should not be allowed. It is the best of all to check pressure in tires before a trip, they still cold so far.
