Choosing good tires can ensure driving safety. At the same time, cost performance, safety, economy and silence should be considered.
1、 First look at specifications and marks
Different models have different specifications of tires. According to national regulations, the same axle must be equipped with tires of the same specification, structure, brand and pattern produced by the same manufacturer, otherwise the driving safety will be compromised. This is especially true for four-wheel drive off-road vehicles, and not only the specifications of the four tires are required to be the same, but also the tire patterns should be the same, so as to ensure driving safety.
It is recommended that consumers check their current tire model before changing the tire. Generally, there are many marks on the sidewall, including trademark, tire pattern, tire specification, load index, speed level, grip level, fuel consumption level, etc. through these marks, the performance of the tire can be seen. For example, a tire with a specification of 195 65 r 15 should be explained in detail as: 195 = cross section width 195 (mm), 65 = aspect ratio 65%, r = radial, 15 = tire inner diameter 15 (inches).
2、 Pattern selection
The two sides of the tire pattern are used for friction and the middle is used for drainage. It is generally divided into three types: single guide pattern, symmetrical pattern and asymmetric pattern. Among them, asymmetric patterns are widely used, and hard tread patterns and solid outer tire shoulders are adopted in the outer area to ensure sufficient touchdown area, more stable and safe driving on curves, and wear resistance during sharp turns. The inner area adopts an open tread pattern and minimizes ground contact, which has excellent drainage and excellent waterproof and sliding function.
3、 The tire speed level shall match the maximum speed of the vehicle
The speed level actually refers to the maximum speed allowed by the tire. Generally speaking, the higher the speed level, the better the performance of this tire. If the driver's vehicle has a top speed of 180 km / h, the tire with a top speed of 160 km / h obviously does not match. Choose a tire that is higher than the top speed of the car. There are several common speed levels: H (210 km / h), V (240 km / h) and w (270 km / h).
4、 Select tires according to the driving environment or driving habits
If the vehicle is often used for off-road sports in mountain roads, mud and other environments, choose tires with strong traction to enhance the trafficability of the vehicle. If vehicles often drive on urban roads, tires with good comfort and handling are more suitable. If you often run long distances, considering the high temperature brought by long-term driving, you should consider the use of some special tires, such as anti burst tires.
5、 Pay attention to the location of tire purchase
Try to go to 4S stores and some brand franchise stores instead of roadside stores. Regular stores have regular purchase channels. In terms of quality, the manufacturer is guaranteed and the service is relatively comprehensive.
