Can a tire be used if the sidewall is scratched?
2 Answers
Tire sidewall is scratched can be used, but it is not recommended. The rubber on the sidewall of the tire is very thin and prone to blowout from the damaged area. It cannot be repaired and it is recommended to replace it. Tires are ring-shaped elastic rubber products installed on various vehicles or machinery for rolling on the ground, mounted on metal rims. The functions of tires: 1. Support the vehicle body and buffer external impacts, achieving contact with the ground and ensuring the driving performance of the vehicle; 2. During driving, they endure various deformations, load forces, and high and low temperature effects, possessing high load-bearing performance, traction performance, and cushioning performance; 3. They have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.
Having run an auto repair shop for years, I've seen numerous cases of tire sidewall damage. Honestly, the sidewall is the most vulnerable part of a tire - once its cord layers are compromised, it's like damaging human tendons and bones. Last week, a customer ignored a sidewall cut caused by a stone, which resulted in a sudden blowout on the highway (fortunately without casualties). If you notice bulging or exposed white cord layers at the damaged area, replace the tire immediately! I always advise customers to measure scratch depth with a coin: anything over 2mm is dangerous. Always park carefully to avoid curbs, and steer clear of sharp stones hidden in roadside weeds.
