Can a damaged outer part of a tire be repaired?
3 Answers
If the damaged area does not exceed 6mm, it can be repaired. If it exceeds this size, it is recommended to replace the tire directly. Below is relevant information: 1. Types of tires: Pneumatic tires are divided into two types based on their structure: tubed tires and tubeless tires. Passenger cars commonly use tubeless tires. Depending on the arrangement of the internal cord ply and buffer layer, tires can also be classified into radial tires and bias-ply tires. Radial tires are widely used in vehicles. The tire sidewall is marked accordingly. 2. Functions of tires: Tires are in direct contact with the road surface and, together with the vehicle's suspension, help absorb shocks during driving, ensuring good ride comfort and smoothness. They also ensure strong adhesion between the wheels and the road surface, improving the vehicle's traction, braking, and off-road capability. Additionally, tires bear the weight of the vehicle.
Hey, speaking of a chunk missing from the outer side of the tire, I have to remind you - it's generally not recommended to repair that, especially sidewall damage which carries the highest risk. The outer tire area bears significant pressure, and patches there often lead to air leaks or even blowouts. I've seen many owners try to save money by repairing outer damage, only to have accidents on highways - losing big money and compromising safety. Best to get it professionally assessed immediately. If the damage is small and in the central tread area, technicians might suggest an internal patch, but most cases they'll advise replacement. New tires cost more, but safety comes first, especially if you frequently take long trips or transport elderly/children. Always park clear of curbs and sharp objects, and conduct regular tire wear inspections to prevent such issues.
Whether to repair a damaged spot on the outer tire depends mainly on the location and size of the damage. If the damage is on the sidewall or shoulder, definitely don't repair it - those areas are too thin and can't withstand impacts after patching. A small hole in the central tread might be temporarily repairable, but it requires professional internal rubber cement, not just a simple patch. I remember last year when my tire scraped against a curb, the mechanic said a sidewall crack meant immediate replacement - saving on repair costs isn't worth the risk of a blowout that could endanger myself and others. Now I've developed the habit of checking tire condition during car washes to address small damages early. Bottom line: safety comes first, so don't hesitate to get it inspected at a repair shop.
