Pressure in tires (including a spare wheel) is checked 1 time in 2 weeks, but at least 1 time a month. 
With a low pressure in tires controllability the car, profitability worsens, and also the probability of a rupture of the tire because of an overheat increases. Besides, with the lowered pressure consolidation of a board of the tire worsens. At big pressure drop deformation of a wheel and (or) stratification of the tire is possible. 
With too high pressure depreciation decreases, controllability worsens, wear in the central part of a protector amplifies, danger of a rupture of a tire when driving on the bumpy road increases. 
Follow the following rules: 
      – check pressure only in cold tires, not less than 3 hours later after a trip, or after a trip for distance no more than 1,5 km;         – it is not allowed to determine pressure by appearance of the tire, measure pressure by the manometer. Driving and comfort of a trip worsen even at change of pressure only upon several tenth shares of the atmosphere;       – it is forbidden to reduce pressure in tires after a trip.   |
