Car tires include spare tires and must be checked regularly every month. During the inspection, observe the tire surface for cracks or scratches. It's best to put gloves on the inside of the tire and check for suspicious traces. As long as the slightest suspicious point is found, you should immediately ask the car dealer to do a detailed inspection. Tired tires do not want to throw. If it is found that the surface of the tire is not properly worn, it should be thought that there may be problems with the adjustment of the toe of the wheel and it is necessary to repair it. Outer edge wear If observed along the direction of travel, there is a greater wear on the outside edge of the tire, indicating that the tire is often under-inflated, ie, the pressure is not enough. If possible, inflate according to the "highway" standard, which means that there are an additional 30,000 pas above the normal standard. It is important to know that under-inflated tires are not conducive to rainy days and the grip will be significantly reduced. Convex and corrugated wear If it is found that both sides of the tire land are convex wear, and the tire periphery is also corrugated wear, indicating that the car's shock absorbers, bearings and ball joints and other components wear more serious. It is recommended that you check the wear of the suspension system and replace worn parts before replacing the tire. Otherwise, even if you change the tires will not help. Uniform wear on the surface Once the tire has been dried, the tire has reached the end of its life and must be replaced. In addition, the pattern also has the effect of dissipating water in the road area, so it is an important link to maintain the car's grip. If the wear has reached the standard depth of the tire tread (usually 1.6 mm, the width of the tire is greater than 175 mm is 2 mm), it will be replaced. Central wear If it is found that the central area of ​​the tire is heavily worn, this indicates that the tire is often over-inflated. Be sure to check the accuracy of the pressure gauge and adjust the pressure. It is important to know that the tire must be inflated only when it is running at high speed or when it is heavy. Tire side crack This situation is often caused by poor maintenance or driving on rocky roads and construction sites, so that hard objects come into contact with the tires, causing damage to the inner layers of the tires under heavy pressure. Should act immediately. If the repair is not good, replace the tire. Tire wear inside The inside of the tire is worn and the outer edge is burr-like. It is common for some old cars to have a bad suspension system, which causes the entire vehicle body to sink deep. This shows that the tire deformation, the symmetry of the two tires has been affected. If conditions are available, it is best to replace the shock absorbers, ball joints, and other accessories. However, if the cost is too high, consider asking a professional mechanic to adjust the front axle and tire angle.
