Can a Scratch on the Outer Side of a Car Tire Be Repaired?
2 Answers
Scratches on the outer side of a car tire cannot be repaired because the repair process involves grinding away some of the rubber, making it thinner. Most repair shops do not offer repairs for the outer side of tires and usually recommend replacement instead. If the scratch on the tire sidewall is not severe and has not damaged the tire's cord layer, leaving it unrepaired is generally not a major issue. Car tires are one of the essential components of a vehicle, directly contacting the road surface and working with the suspension system to absorb shocks during driving, ensuring good ride comfort and smooth operation. They also maintain strong traction between the wheels and the road, improving the vehicle's traction, braking, and off-road capabilities, while bearing the weight of the car.
Can the outer sidewall of a tire be repaired? Let me explain the tire structure in detail. A tire consists of the tread and the sidewall. The tread is thick and can be puncture-repaired, but the sidewall is very thin, composed of multiple layers of rubber and fabric, bearing lateral pressure. If the outer sidewall is scratched with a depth exceeding 2mm or if the cords are visible, its structural integrity is compromised. Temporary repairs like rubber plugs or patches won't hold securely, increasing the risk of bulges or blowouts during high-speed driving, which could lead to accidents. I previously consulted technicians who all emphasized that sidewall damage fundamentally cannot be effectively repaired – replacement is the only safe option. Safety first; don't risk cost-cutting. I recommend visiting a professional shop to measure the scratch depth with a gauge before deciding on a new tire. Regularly avoid curbs when driving and develop a habit of periodic tire inspections to prevent such issues.
