Is it necessary to replace the tire if the sidewall is punctured?
2 Answers
For safety reasons, it is best to replace it promptly. The tire must be replaced if any of the following issues occur: 1. The diameter of the puncture hole in the tire crown exceeds 6 millimeters. 2. The sidewall is punctured or bulging. 3. The tire bead or tread is deformed, the rubber is corroded, or the tire is damaged due to underinflation and rolling. Here are some methods to extend the lifespan of your tires: 1. Avoid speeding: Excessive heat generated from high-speed driving can accelerate tire wear and reduce durability. 2. Avoid sharp turns, rapid acceleration, hard braking, and driving over curbs. 3. Try to avoid potholes and obstacles on the road, and slow down when driving on uneven surfaces.
As a friend who often helps others with car repairs, I have to say that a puncture on the tire sidewall usually means replacement is the only option. The sidewall is particularly thin and lacks the reinforcement of steel belts, so even if you manage to patch it, it won't withstand the pressure of high-speed driving. I've dealt with several cases like this recently—patched tires often develop bulges or leaks after a short time, making them even more dangerous. Especially in hot weather, the risk of a blowout increases as tire temperatures rise. If you must repair it, special internal patches are required, but the cost is similar to buying a new tire, and the results aren't reliable. Always park carefully to avoid scraping curbs, steer clear of deep potholes, and regularly check the sidewalls for bulges or cracks. When replacing tires, it's best to change them in pairs, as mismatched tread depths can affect traction.
