Does a Scuffed Tire Have Any Impact?

If the tire sidewall is already damaged, it is not recommended to repair it. If the cut has not reached the cord material, theoretically it can continue to be used, but regular checks are needed to see if the wound expands or if the cords are damaged. The maintenance methods for tires are as follows: Safe Storage: All tires should be stored in a cool, dry, and dark indoor environment, avoiding exposure to sunlight, oil, acid, hydrocarbons, etc., to prevent tire erosion. Tire Maintenance: Regular tire rotation, selecting appropriate tread patterns, routine maintenance, periodic checks of tire pressure, timely repairs after damage, and frequent removal of stones and debris from the tread are all important factors in extending tire life. After a period of use, factors such as road camber, braking, and different tire mounting positions can cause significant differences in tread wear. Therefore, timely rotation and mounting are essential to address uneven wear and extend tire lifespan. Ensure Standard Pressure: When tire pressure is below the standard value, shoulder wear increases sharply. When tire pressure is above the standard value, the reduced contact area increases the unit pressure, leading to increased wear in the center of the tread. It also increases tire rigidity, raising the dynamic load on the wheel, which can easily cause tire blowouts.
A chunk of rubber peeling off the tire is indeed concerning. I once saw a similar case at a highway service area. The key factors are the location and depth of the damage. Sidewall damage is more dangerous because the sidewall is thinner, and once the inner cord layer is exposed, it can easily bulge or even blow out. Damage on the tread is slightly better, but the size matters - a deep pit larger than a coin can compromise the tire's structure. Last time when helping a friend inspect his tire, we found a missing chunk and carefully checked with a flashlight for exposed white cords. When cords were visible, we had to replace it. At highway speeds, tires endure tremendous stress where minor damage can worsen, especially during summer heat. Don't cut corners - the safest approach is having a professional shop lift the vehicle for proper inspection.
