Tire repair and replacement of the use and maintenance of car tires

The car in this period auditorium, we introduce some basic knowledge on the use and maintenance of car tires.
Tire repair and replacement
The tire life is three years or 60,000 kilometers. Based on the actual use of the environment and the situation, it may be life will be shorter.
The main parameters to determine whether the tire has reached the end of its life cycle tire tread wear indicator. Tire wear mark exposed, it will leave a clear imprint of the rubber in the tire on the road on the line, which proves that the tire must be replaced. In addition, maintenance tire tread feet measuring tread depth below 2mm (some tires may be required by the tread depth is a lower limit of 1.6 mm), also indicates the need to replace the tires. Wear after the tire grip will be substantially weakened, directly affect the steering, braking and driving ability, a great threat to traffic safety.
Another tire life is time.
The importance of the automobile tires are self-evident. Critical uses as a vehicle steering, braking, driving the core components, as well as carrying body of each function are closely related to the vehicle's handling and security. Therefore, the correct use, maintenance tire, the basis of the safety car.
If the wheel using low frequency, less mileage, not, not to replace it? Answer is the same need to be replaced in accordance with the time period, the general cycle is three years. This is mainly the and tire product shelf life. Lives to the mileage did, like the need to replace the tires.
Replacement tires, pay attention to the identification of tire retreading.
Due to special factors in the domestic market, the aftermarket "bulk" market, tire retreading prevalent. General retreaded tires do not wear, poor security, and can be identified from the appearance of simple: "lanugo" (ie, the tread rubber line) left due process if a pull off basic it can be concluded that retreaded tires, two tires abnormal smooth surface and bright colors, hand touched can leave finger prints may be retreaded tires. Replacement tire recommendations back to the 4S. Generally, 4S tire sources will supply channels from OEMs, quality, more secure.
Replacement tires to ensure consistency.
The first parameter consistency. In general, do not change the parameters of the original car's tires, need because the installed dimensions should be big, not small (ie, the new tire size can not be less than the original tires). Any changes to the large size of the tire, ensure that the trip computer match the parameter with the big tires, mileage and other information to ensure accuracy at the same time to ensure the normal operation of the electronic system with brake and auxiliary steering. To Fox, for example, if the original changed to 205/55/R16 tires 195/65/R15, we need to change the tire after conjunction to change the parameters of the trip computer, ensure that the match. In addition, change the tire should not replace the tire tread and structure, as well as load index and speed index of these standards.
Another to change the tire, "consistency" is to ensure that the four be replaced at the same time, which is closely related to the vehicle's handling, stability and security. Because of some special reasons (such as tires newer one bad, not wholly new ones), must also ensure that the pairs replacement, especially the steering wheel and the drive wheels must be the same on both sides of the. There is a day-to-day problems facing the tire repair. Sometimes one of the tires were slashed, and do not want to replace a new tire on the approach taken to fill tires because of careless. "Cold patch" for the tear in the "wound" of less than 2 mm, hot fill the entire cushion gum area can not be too large. Cold patch or hot fill tires do not apply to the more than three hours of high-speed continuous use, otherwise there is a puncture dangerous. If the break is too large, it is recommended to directly change the tire.
