Can a Repaired Tire Be Used on Highways?
2 Answers
A repaired tire can be used on highways, as it performs similarly to its original state and meets the driving conditions for highways. The maintenance methods for tires include: 1. Regularly checking tire pressure; 2. Periodically inspecting tires for bulges, cracks, cuts, punctures, or abnormal wear; 3. Removing foreign objects such as stones, metal pieces, or nails from the tire treads; 4. Performing wheel alignment or tire balancing. The hazards of unstable tire pressure include: 1. Reduced friction and adhesion of the tire, affecting braking performance; 2. Causing steering wheel vibration or deviation, reducing driving comfort; 3. Accelerating localized wear of the tread pattern in the center of the tire.
Can a patched rear tire be used for highway driving? Having driven for many years and patched tires several times, I believe it depends on the quality and location of the repair. If it's a professional hot patch with the hole in the middle of the tread and not too close to the side, highway driving is generally fine. Last time after patching, I drove a long distance maintaining 120 km/h without issues, but post-repair, tire balancing is essential, and checking for stable air pressure is a must. The repair method also matters—cold patches with plug strips are unreliable and prone to leaks or blowouts under high-speed pressure; I've seen accidents happen. Temperature plays a big role, making hot summer days riskier. If the tire is aged, even a good patch can fail, so tires over five years old should be replaced. Before highway driving, test the patched tire in the city for a couple of days to confirm safety. In short, safety first—if unsure, don’t risk it; consult a reliable technician for evaluation.
