Just as there are grading standards for automobiles, there are uniform mandatory standards for the quality grades of automobile tires. And this mandatory quality rating standard, we all call it 3T index.
As shown in the figure, 3T indicators include tread wear, traction and tire temperature. For example, in terms of traction performance, it can use AA, A, B and C to classify the traction performance of tires. The traction performance of AA represents the strong grip of tires, while the traction performance of C is very weak. For example, the tire temperature index is judged by three grades: A, B and C. A temperature index indicates that the tire has excellent high temperature resistance, and C temperature index indicates that the tire has poor high temperature resistance.
Different from the other two indexes, the wear resistance index of tires is not as high as possible. If the tire wear resistance is high, the comfort of driving a car will be greatly reduced. After all, wear-resistant tires will be hard, and the cushioning ability of tires will not be very prominent. Generally speaking, especially for family cars, the wear index of tires is 280-320.
As for the choice of tires, what is trustworthy on the market at present is the kind that comes and goes.
Michelin
As a company with a tire manufacturing history of 130 years, Michelin tire has the inherent advantages of strong grip, good drainage and strong softness. However, the wear resistance and high price have also discouraged many people.
Bridgestone
Bridgestone has good wear resistance, acceptable price and economic benefits. Of course, the comfort is definitely not as good as Michelin.
German horse brand
German horse brand tires have the advantage of good mute effect; But the grip is average and the wear resistance is not strong.
Finally, you have to understand that tires, no matter how expensive, have a life. The choice of tires is very important, but the regular replacement of tires can not be ignored.
