Any low pressure tire can cause excessive heat and may eventually cause a sudden tire crash. In addition, no matter the tire inflation pressure is too high or too low, the tire tread will be partially worn out, so as to shorten the service life of the tire.
Please check regularly for all tire pressure during cooling (at least once a month), including the spare tire. The correct inflation rate of the tire under cooling conditions shall be based on the parameters recommended by the vehicle manufacturer. If the pressure decreases too quickly, please find out the cause (for example: nail sticking, cutting, rubber aging, cracking, etc.).?The definition of tyre cooling: at least three hours after parking, or no more than 2 km of tire travel. If you can only measure the tire pressure during the hot tire, please subtract the measured tire pressure value by about 0.3 bar (=4psi), that is, the tire cooling and charging pressure.
When the radial tire is inflated, due to the structural reasons, its subsidence and the ground area are larger, often mistaken for insufficient inflation and excessive inflation. Or conversely, because of its subsidence and the ground area is larger, and when the pressure is insufficient, also mistaken for adequate.
[warm tips]1, inflatable should pay attention to safety. Always use the barometer to check the air pressure to prevent excessive inflation and to cause the tyre to burst.2, after stopping running, to heat the tyres after inflation, because traffic will increase when the tire temperature, the pressure effect.3. Check the valve. If the valve and valve core do not match properly, the phenomenon of protruding concave and other defects can not be inflated and air pressure is measured.4, inflatable should pay attention to cleaning. The filled air shall not contain water or oil to prevent deterioration or deterioration of the rubber in the inner tube.5, the inflatable should not exceed the standard, then deflated, nor can not be inflated due to long-term outside can not be inflated.6, before the air should be dust valve mouth clean, do not loosen the valve core, the valve on the water filling with soap after, leak check.
General car tires in winter 2.5KPa, summer 2.2KPa, tire side of the tire can withstand the highest pressure. A reasonable air pressure is the highest pressure 70%-80% on the tire, but the barometric pressure is best not above the ceiling pressure indicated on the tire.
