How to Repair a Scratched Tire?
2 Answers
First, the tire must be removed from the rim and inspected by a professional tire dealer to determine if it can be repaired. Here are situations where a scratch on the tire sidewall cannot be repaired: 1. Sidewall damage: There is a risk of tire blowout. Generally, the sidewall of a tire is thinner, making it difficult to repair. The high tire pressure makes it prone to bursting at the damaged area. 2. Abnormal tire damage: Such as when the tire sidewall is crushed or damaged. In such cases, it is often necessary to replace the tire. When selecting a new tire, it is best to choose a product with the same or similar tread depth on the same axle to avoid issues like excessive tire wear.
I enjoy DIY car repairs and have encountered tire cuts several times. First, squat down to carefully inspect the wound depth: if it's just surface scratches without exposing the cord layer, you can ignore it completely; but if cords are exposed or there are cracks, it needs patching. I keep a tire repair kit handy—the steps are simple: clean the wound, smooth it with a file, insert a rubber strip and press firmly, then apply some glue to seal. After that, inflate and test for leaks, then drive a short distance and check again. This method is cost-effective and quick—I've had no issues after repairs, but remember to check tire pressure before highway driving to ensure safety. Small cuts are fine for DIY fixes, but for large cracks, it's best to consult a professional.
