Extended data:
1, tire width
The tire width is determined by the wheel hub width, and the tread width also determines the grip performance of the tire. Theoretically, the greater the contact area between the tread width and the ground, the greater the grip of the tire and the better the handling performance. However, due to the increase of rolling resistance of wide tires, fuel consumption will also increase. Therefore, in the classification of tires, the car that pursues performance will choose wider tires, but if it is a family economy car, its tread will not be very wide. ?
2. Tire flattening rate
Flatness refers to the percentage of tire cross-sectional height to its maximum cross-sectional width. The tire with high flattening rate has long sidewall, strong cushioning ability and relatively high comfort, but it has poor feeling on the road surface and weak lateral resistance when turning. On the other hand, tires with low flatness and large inner diameter are very sensitive to the road surface, have large lateral resistance when turning, and have strong vehicle maneuverability because of their short sidewall, wide tread and large contact area.
Step 3 Choose a tire brand
The most direct and convenient way to buy tires every day is to start with the tire brand, just like choosing a car. The better brands are Michelin, Bridgestone and Goodyear. But there is no need to blindly pursue high-end brands. After all, what is suitable is the best. Different models, different road conditions and different needs are suitable for different tires. Each brand of tires is also divided into different grades and series. Generally, the high-end focuses on sports and silence, while the low-end focuses on anti-manufacturing and wear resistance.
4. Tire tread pattern
In addition to beautiful appearance, tire tread directly affects the handling, noise, drainage performance, wear resistance and so on. The most common tire patterns are transverse groove pattern, straight groove pattern, straight transverse groove pattern, block pattern and asymmetric pattern. Among them, the horizontal groove pattern has good friction and the straight groove pattern has small driving resistance, which is suitable for outdoor driving of SUV, the square pattern is suitable for mud or snow, and the asymmetric pattern has better drainage. ?
5. Tire performance index?
Automobile tires must have three signs of tire wear, traction and fever, which is called "three T" for short. Wear index is a sign to measure the wear performance and service life of tire tread. The higher the value, the more wear-resistant the tire is. Tire traction index, which measures the adhesion between tire and ground, is divided into four grades: AA, A, B and C, among which AA is the highest. Heat generation index refers to the ability of tire to resist heat generation, which is related to the high-speed performance of tire. It is divided into three grades: A, B and C, with A being the best.
