Can a scratched tire without exposed cords be used on highways?
2 Answers
A scratched tire without exposed cords should not be used on highways. If the sidewall of a car tire is cut or damaged, it is best to replace it promptly, as driving at high speeds can easily lead to a tire blowout, posing a significant safety hazard. Reasons why a scratched tire should not be used on highways: The weakest part of a tire is its sidewall. Damage to this area not only increases the risk of a blowout but also makes repairs more difficult, so the tire should be replaced as soon as possible. Solutions for a scratched tire: If the cords are not exposed, it means the structural integrity of the sidewall has not been compromised, and the tire can still be used. However, for safety reasons, it is best to take it to a tire repair shop to patch the damaged area and rebalance the tire, then install it on the rear axle or use it as a spare. The sidewall is the most vulnerable part of the tire, and the rubber here protects the inner cord layers. If it is damaged again, the cords may be compromised, which is extremely dangerous.
A tire with a scratch but no exposed cords is really unsafe for highway driving. I've experienced a similar situation before. That time when I drove on the highway, there was a small scratch on the tire. I thought it would be fine since the cords weren't exposed, but halfway through the journey, the car suddenly started shaking violently. Fortunately, I pulled over in time to check and found that the scratch had deepened, nearly causing a blowout. If the rubber layer of a tire is damaged, even if the internal cords aren't exposed, the changes in pressure and temperature at high speeds can amplify the risk. A tire is like a shoe—even if a small part is worn out, running fast can cause it to completely come apart. Especially on the highway, as speed increases, the friction on the tire becomes greater, making weak areas prone to cracking, which can lead to catastrophic blowouts or loss of control. I strongly recommend that if you encounter this issue, don't take the risk—go to a repair shop first and use professional equipment to measure the depth of the damage. Safety comes first. Highway driving is no joke; a small mistake can lead to major consequences. Spending money on new tires or repairs is worth it—your life is at stake.
