The reasons for the abnormal sound of the left front wheel of the new Volkswagen Jetta are as follows: First, the wheel hub screw is loose; Second, tire tread deformation, unpacking and insufficient air pressure; Third, it is caused by gravel in the tire tread; Fourth, it is caused by the damage of shock absorber and bearing. As a part of the car's direct contact with the ground, the main function of the tire is to make the car work normally. However, different driving wheel conditions have different requirements for tires. According to the different surface patterns, tires can be divided into four types, namely tread tires, transverse tread tires, mixed tread tires and off-road tread tires. According to different seasons, tires can be divided into winter snow tires, summer tires and all-weather tires. In winter, the material of snow tires is soft, and the tread groove is wider and deeper, which can make the vehicle have stronger grip and skid resistance when driving on ice and snow roads, thus ensuring the adhesion of the vehicle when driving on low-temperature roads.
