Can a Cut in the Car Tire Outer Tread Be Repaired?

[Clayton]

A cut in the car tire outer tread can be repaired. Minor damage can be fixed at a repair shop, while severe damage requires tire replacement. Below is an introduction about tires: Tire Maintenance Methods: Regularly check tire pressure; inspect tires for bulges, cracks, cuts, punctures, or abnormal wear; remove foreign objects like stones, metal pieces, or nails from the tire tread; perform wheel alignment or tire balancing. Tire Lifespan: Manufacturers generally set the service life of tires at 3 years. If a vehicle is driven 20,000 kilometers per year, consider replacing the tires in 2 to 3 years. For vehicles driven around 10,000 kilometers annually, replacement should be considered in 4 to 5 years. Even if the vehicle is driven only 5,000 kilometers per year, tire replacement should still be considered after 4 to 5 years.

Last time I drove a long distance, a piece of broken glass cut a chunk out of the sidewall of my tire. The car felt unstable while driving, so I immediately went to a repair shop. The mechanic told me whether it could be repaired mainly depends on the location and size of the cut: if it's on the tread that frequently contacts the ground and the wound is small and shallow, a patch or mushroom plug can be used to keep it going; but the sidewall simply can't be repaired because it's thin and under high stress, and even if patched, it's prone to cracking again. He advised against taking the risk of repairing the sidewall—although a new tire is more expensive, safety comes first. Now I've made it a habit to check my tires after parking, especially after driving on rough roads. Remember, folks, small issues can be fixed, but major damage calls for a new tire—don't gamble with safety.

From a technical perspective, whether a cut tire can be repaired depends on several factors. If the tread's cut hasn't damaged the cords and is less than a few millimeters long, it can generally be fixed with a patch or mushroom plug. However, sidewall repairs are much riskier and prone to blowouts. The overall wear condition of the tire must also be considered during repairs, as old tires become unreliable even after patching. I recommend taking a cut tire to a professional shop for inspection and evaluation immediately—don't attempt DIY fixes to avoid accidents. While driving, avoid roads with sharp objects, and regularly check tire pressure and tread wear. Prevention is always better than cure.

Safety should never be overlooked. If the outer layer of a tire is cut, repairs may not be reliable, especially for sidewall damage. The strength of a repaired tire decreases, making it prone to blowouts at high speeds, which can lead to accidents. Experience tells us that many repaired tires encounter issues during subsequent drives. Therefore, when faced with a cut, don't opt for a quick fix. Have a technician thoroughly inspect it before making a decision. Remember, tires are the core of a vehicle's safety. Maintaining them well can reduce the risk of accidents—saving lives is paramount.
