When is it suitable to repair a tire?
1. Tire Repair Depends on Damage Size, Location, Age, and Wear
Whether a tire should be repaired or replaced mainly depends on the extent of the damage, where the wound is located, the tire’s age, and how worn the tread is. A repair may be suitable in the following situations:- Small puncturesSmall wounds caused by nails or sharp objects may be repairable when the internal tire structure is not damaged.
- Minor cracksSmall cracks may be repairable only when they do not damage the cords and do not affect the tire’s overall strength.
- Good overall tire conditionThe tire should be of moderate age, not badly aged, and not severely worn.

3. Some Tire Damage Should Not Be Repaired
- Poor wound locationIf the puncture is on the sidewall or shoulder of the tire, do not try to repair it. These areas are difficult to repair reliably and the repair effect is usually poor.

- Internal damageIf the tire has internal damage such as a broken belt, it should be replaced completely.
- Aging or multiple previous repairsIf the tire has been used for many years, more than 6 years, has long mileage above 50,000 miles, or has been repaired many times before, replacement is recommended to protect driving safety.
