Among many parts of the vehicle, the tire is the only part that touches the ground and bears the weight of the vehicle, so its importance is self-evident. For automobile tires, the weakest part is the sidewall. Once there is a problem with the sidewall, many car owners are also very worried. However, bumps are inevitable during driving, so can the broken skin on the side of the tire be repaired? If the tire is only broken on the side and there is no air leakage, in this case, it means that the tire is only damaged by the surface rubber and can be repaired; If the sidewall is seriously damaged, such as the sidewall bulge or the rubber is completely cracked, it is necessary not only to repair the tire, but also to replace it. When the tire sidewall is damaged, although many auto repair shops do not recommend repair, if only the tire sidewall is damaged, there are some minor damages. Changing tires under such circumstances may make car owners with average economic level feel more extravagant. In short, in addition to the specific damage of tires, it is also necessary to combine the economic situation of the owner to decide whether to replace the tires.
