Does a small scratch on the tire have any impact?
2 Answers
Generally, a small scratch on the sidewall of a tire does not affect its use. However, if a layer of rubber is missing, it is not recommended to continue using it. The rubber on the sidewall of a tire is very thin and can easily burst from the damaged area, and it cannot be repaired because repairing requires grinding away part of the rubber, making it even thinner. Most repair shops do not repair tire sidewalls and usually recommend replacement. Additional information: Car tires are one of the important components of a vehicle. They directly contact the road surface and work together with the car's suspension to cushion the impact during driving, ensuring good ride comfort and smoothness. They also ensure good adhesion between the wheels and the road surface, improve the vehicle's traction, braking, and off-road capability, and bear the weight of the car. The important role of tires in vehicles is increasingly being recognized.
From the perspective of driving safety, a small scrape on the tire should not be underestimated. If that small cut is on the sidewall or exposes the inner cord layer, it may not withstand the pressure during high-speed driving and could lead to a blowout. I have a friend who experienced a similar accident—he brushed the tire against a curb and didn’t take it seriously, only for it to go flat during a long-distance trip, nearly causing an accident. It’s recommended to measure the depth of the scrape immediately with a ruler; if it exceeds 2 millimeters, it’s time to replace the tire. Regularly check the tire pressure while driving and keep it at the standard value to reduce wear and tear risks. Tires are like shoes for the car—damage can affect overall stability, especially during rain or sharp turns, where reduced grip can easily lead to skidding. Safety is not something to be careless about. Spending some money to get it checked and replaced at a reputable shop is always better than dealing with an unexpected accident.
