As a consumable, tires need to be replaced after a period of use. First of all, the car should adjust the front and rear wheels diagonally every 10,000 kilometers, because the current family cars are basically front-wheel drive, the front wheels are responsible for both steering and driving the whole vehicle, which leads to the different degree of wear of the front and rear tires, and the wear of the tires is also related to the distribution of vehicle weight, and the tire rotation is of great help to the uniform wear of the tires. Tires with different specifications, structure and wear resistance have a great influence on the handling performance and stability of the vehicle. In addition, tire rotation should be carried out in a professional maintenance station, and it is best to do four-wheel alignment again after changing tires, although this is not mainly for tire maintenance, but it is still very good for the driving of the whole vehicle.
Tires wear to a certain extent must be scrapped, generally when the wear mark on the tread should be scrapped, ordinary tires in the driving of about 80,000 kilometers is also the time to scrap. However, many people think that only the pattern polishing needs to be replaced, in fact, when the road surface is slippery, long-term use of a car with serious tire wear, the steering wheel and brakes almost completely fail, the car is easy to produce side slip and deviate and cause accidents. If you panic and press the brakes at this time, it is very dangerous, and the correct thing to do is to hold the steering wheel with both hands and gently press the brakes to reduce the speed.
Also, have you ever been in a hurry to change your spare tire? Don't worry, you must also have certain skills when changing the spare tire: do not change the spare tire on uneven roads or ramps, and place the tire brake pad on the outside of the tire at the diagonal position of the replaced tire when removing the tire to prevent the car from moving. Hook up the gear and pull up the hand brake. Using a wheel screw wrench, turn the screw about one-half to the left, lift the car with a jack, confirm the correct position of the jack, and then change the tires. Lock the screw mother and screw nails, put down the jack tire to the ground, and then further lock the screw mother one by one in the diagonal form. After changing, check whether the air pressure of the tires is balanced. When you're okay, you can practice and be prepared.
Moreover, there is another problem that many people overlook, that is, the life of tires, the international definition of tire life is generally three years, the implication is: even if it is a brand new tire, it can not be used if it is left for 3 years. Moreover, in terms of tire repair, you must find a professional store for hot repair, pay attention, must be hot repair, can not plug rubber strips to cope. Otherwise, it is easy to cause the belt layer and other parts inside the tire to age, forming a bulge, which poses a threat to driving safety. You can hit the highway after repairing, but be careful that the repaired tires should be mounted on the rear wheels. Of course, if there is a problem with the repairable area such as the sidewall, the tire must be discarded and must not be used again.
