Can a tire still be used after being patched 5 times?
1 Answers
When a tire has been patched 3-5 times, it should be replaced directly. When a tire has a puncture wound causing air leakage, even if it is repaired by patching, the wound area remains the weakest part of the tire. Over time, especially when driving in rainy conditions, water can seep into the wound, eventually leading to renewed air leakage. Here are situations where replacement is necessary: 1. Severe tread deformation/damage to the tire body: If the tread is deformed or the tire body is severely damaged, the tire must be replaced. Tread deformation is actually caused by damage to the tire body. When the tire body is subjected to significant force, its internal structure is damaged, leading to deformation, which in turn affects the tread, compromising vehicle safety. 2. Severe tread damage: If the puncture hole in the tread exceeds 6mm in diameter, the punctured tire must be replaced to ensure driving safety. 3. Bulging: A bulge on the tire sidewall is a result of broken cords in the tire's fabric layer. There is no value in repairing it; the tire must be replaced. If a repair is attempted, the patched tire will remain a hazard that could blow out at any time. 4. Severe sidewall damage: If the outer rubber of the sidewall is completely cracked, and the tire's airtight layer, fabric layer, and protective layer are fully compromised, the tire must be scrapped. If a tire is punctured by a nail and the driver continues to drive without immediate repair, the inner side of the tire may be severely damaged by the wheel rim, necessitating replacement.
