Can a punctured tire sidewall be repaired?
2 Answers
Tire sidewall punctures cannot be repaired and require replacement: 1. Tire wear is normal for car tires, but severe wear can be very dangerous; 2. Surface wear: When the tread pattern is completely worn smooth, it indicates the tire has reached the end of its service life and must be replaced. Failure to replace promptly may result in near-zero friction between the tire and road surface, making the vehicle prone to skidding during sudden braking or even experiencing blowouts, which is extremely hazardous; 3. Center wear: If the center portion shows severe wear approaching the wear indicators, immediate replacement is also necessary. Continuing to drive with such wear poses safety risks.
If the sidewall of a tire gets punctured, I think it's best not to patch it. The sidewall is particularly thin and constantly subjected to pressure and bending, making it prone to rupture after repair. A blowout at high speed is extremely dangerous and could lead to an accident. I once encountered a similar situation, and when I asked at the repair shop, the mechanic said it couldn't be patched and had to be replaced. For safety's sake, spending a bit more on a new tire is worth the cost. Avoiding gravel roads when driving and being mindful of wheel positioning when parking can help reduce the risk of punctures. Regularly checking tire wear and pressure is also crucial—prevention is better than cure. Remember, life is priceless; don't take risks to save money foolishly.
