We all know that car is running, the tread and sidewall constantly by stretching and compression, the rubber molecules and molecular between, between cord and rubber, inner tube and tire, between tire and rim and friction between tire and road surface and hot. Long drive or drive the hot summer when the temperature of the tire will be rising, reduce tire material mechanical properties, wear, and easy to cause cord fabric layer, the wire broke off, if the child is in danger of bursting temperature to 95 ℃.
Low tire pressure will increase wear and decrease. When the tire pressure is lower than the standard value, the tire tread increases sharply. Tire pressure is higher than the standard value, because of the tire grounding area reduced, the unit pressure, increase central tire tread wear, at the same time increases the tire rigidity, increase under the dynamic load of wheels, easy to produce the tire body burst. The impact is more severe on uneven roads or at high speeds.
Overload will increase the deformation of the tire, the stress of the tire will increase, the contact area between the tread and pavement will increase, and the relative slip will increase.
The front wheel, too small, will cause the inner edge of the tread to wear seriously; The front beam, overpour, the outer edge of the tread wear serious. The brake assembly is too tight, which will cause the tire to turn uneven and produce slip, drag and wear increase. The imbalance of the wheel is large, and when the gap between the ball joints of the crossbar is too large, and the difference between the central pin is too large, the vibration in the steering wheel will be increased, which will also accelerate the wear of the tires.
The tire size should fit with the model and the size is too large, which will reduce the driving force of the car. Too small a size will overload the tires. In good asphalt and concrete pavement, small decorative tires should be used; Large tread tires should be used on dirt roads or other rough roads. To comprehensively consider the shape of the tire, the height of the pattern, the degree of old and new, the road conditions and other factors, reasonable collocation, the time of the tire replacement.
Do not get too aggressive, try to avoid frequent use of braking and emergency braking; When driving on the turn and the wrong road, it is necessary to prevent the tire from being seriously deformed, or the surface of the tire should be damaged when the obstacle is exceeded. Don’t park your car in areas where there are oil and dirt. Don’t turn the wheel after parking.
Carefully seal the storage of vehicle tires to prevent the tires from being exposed to rain and direct sunlight
