Tire Sidewall Repair
2 Answers
Tire sidewall damage cannot be repaired. The rubber on the tire sidewall is relatively thin, and repairing the tire requires grinding away some of the rubber, making it even thinner and prone to blowouts. Most repair shops do not repair tire sidewalls as it would be too dangerous to drive on a forcibly repaired sidewall. The following situations make a tire unrepairable: 1. Sidewall damage cannot be repaired. 2. Puncture holes in the tread crown exceeding 6mm in diameter cannot be repaired. 3. If there is bead damage/deformation, tread deformation, chemical corrosion of rubber, or underinflation damage, the tire cannot be repaired. 4. Other abnormal conditions make the tire unrepairable. For example: if signs of underinflated driving are visible on the tire (such as sidewall abrasion marks or inner liner bubbles), it's not worth repairing as the tire structure may already be compromised and unsafe for continued use.
When it comes to repairing the sidewall of a tire, I must warn you: it's best to leave it alone! The sidewall is particularly fragile, unlike the tread which has thick rubber layers to withstand pressure. Once punctured or cut, a repaired sidewall is highly prone to blowouts while driving, which can be life-threatening. For instance, I've encountered cases where car owners tried to save a few hundred bucks by getting a hot patch at a small repair shop, only to lose control on the highway shortly after, nearly causing a major accident. Nowadays, many professional shops outright refuse to repair sidewalls due to the high failure rate. My advice is: spend the money on a new tire—don't gamble with your life. Regularly checking tire pressure and wear can also prevent these minor issues. Safety first—it's more important than anything else!
