Tire is a kind of circular elastic rubber product which is assembled on all kinds of vehicles or machines.
Whether the tire is installed correctly or not is directly related to the service life of the tire, especially when the new tire is replaced. For tires with different types and patterns, due to different actual sizes and load capacities of each tire, it is not allowed to mix them randomly.
Too low or too high tire pressure will affect the service life of the tire. If the tire pressure is too low, the radial deformation will increase. The deformation of both sides of the tire wall will be excessive, which will cause the wear phenomenon of the crown and shoulders, and increase the temperature of the tire. It will seriously reduce the service life of the tire. If the tire pressure is too high, the rigidity of the tire will increase. The deformation and the grounding area will decrease. The unit pressure in the middle of the tread will increase, the wear will increase, and the central wear of the tire crown will occur, which will affect the comfort and reduce the service life of the tire. The test shows that if the air pressure is increased by 25%, the tire life will be shortened by about 30%.
As an important part of a car, the main consideration of tire performance is the tire pressure. Too low or too high tire pressure will affect the tire's performance and reduce its service life, ultimately affecting driving safety.
The full name of TPMS is tire pressure monitoring system, which is the abbreviation of "tire pressure monitoring system". The role of TPMS is to automatically monitor the tire pressure in real time during the driving of the car, and to alarm the tire leakage and low pressure to ensure driving safety.
If the load on the vehicle is greater, the life of the tire will be shorter. Especially in the case of overload, it is more prominent. All tires produced by regular tire manufacturers are marked with load index. Tires shall be used within the maximum load capacity corresponding to the specified load index.
All tires produced by regular tire manufacturers are marked with speed class index. Tires shall be used within the maximum driving speed corresponding to the specified speed class index.
In the process of vehicle driving, the tire temperature increases because of stretching, compression and friction.
The parallelism of the front and rear axles, the four-wheel alignment, the working conditions of the braking device and the technical conditions of other chassis parts will affect the service life of the vehicle tires to varying degrees. Once there is a serious traffic collision accident, the owner must drive the vehicle to a professional maintenance station to check and adjust the chassis condition.
If the vehicle is driven on the gravel road or under the bad road conditions for a long time, the service life of the tire will certainly be reduced. This is no exception for off-road tires.
This is directly related to the car owner. Some conditions, such as excessive starting, sudden steering, emergency braking, high-speed driving in bad road conditions, frequent getting on and off the curb and scraping obstacles when parking, etc., will lead to serious tire wear and reduce the service life of the tire.
Factors such as timely transposition, selection of proper tread pattern, daily maintenance, regular inspection of tire pressure, timely repair and frequent digging of stones and foreign matters in tread pattern are all important for prolonging tire life.
The regular maintenance of vehicles is also closely related to the prolongation of tire life. The regular inspection and maintenance of four-wheel alignment, knuckle, wheel bearing and suspension system is important as well.
Five habits can extend the life of a tire.
Air pressure is the key to prolong tire life. If the tire pressure often exceeds 20% of the normal pressure, the service life of the tire will be reduced by 10%. If the tire pressure often exceeds 30% of the normal pressure, the service life of the tire will be reduced by 52%. It is necessary to equip with a TPMS to monitor the tire pressure wherever and whenever.
Tire pressure is the lifeline of tire. If the air pressure is too low, the deformation of the carcass will increase, and the sidewall is prone to crack. At the same time, it will lead to excessive heat generation, aging of the rubber, fatigue of the cord and fracture of the cord.
When the vehicle is driving on the road, there are often some stones squeezed into the tread of the tire. If these small stones are not removed in time, they will puncture the tire for a long time, resulting in air leakage or blowout.
When driving on the road with large camber, it is necessary to drive in the middle as far as possible to avoid and reduce the deviation of the center of gravity of the car, and to reduce the uneven tire wear caused by the increase of tire load on one side.
Front wheel alignment has a great influence on the service life of tire, especially the toe-in and camber of front wheel. Front wheel camber mainly accelerates the wear of shoulder, that is, eccentric wear. Front wheel toe-in mainly accelerates the wear of inner and outer sides of tire.
If people can not fully grasp some influencing factors of tires, it is recommended to check and replace them at a professional tire shop or at a special vehicle repairer in time.
