Can a Repaired Car Tire Be Used on Highways?
2 Answers
Whether a repaired car tire can be used on highways depends on two scenarios: 1. If only the part of the tire that contacts the ground has been repaired, it is permissible to drive on highways; 2. If the tire sidewall has been damaged or the part that contacts the ground has been repaired multiple times, it should not be used on highways. The tire is the only component of a car that comes into contact with the ground, and this component is crucial for the vehicle's driving stability and safety. Tires are made of rubber and will experience aging and wear over time, necessitating regular replacement. After installing new tires, it is essential to perform a dynamic balance test on each wheel to prevent abnormal vibrations during high-speed driving. If abnormal vibrations occur at high speeds, it can affect the car's handling and stability, as well as the comfort of the ride.
As a professional who frequently deals with tire issues, I must emphasize that using repaired tires on highways requires extreme caution. Repairs mainly refer to minor damages like nail holes, which are fixed with patches or plug repairs. However, high-speed driving subjects tires to immense pressure, with extremely high temperatures and friction, which can easily cause the repair point to fail, leading to air leaks or even blowouts. A blowout on the highway is a matter of life and death. The type of tire repair is crucial: professionally repaired punctures in the central tread area may still offer some reliability, but sidewall repairs should never be used for high-speed driving due to their weaker load-bearing capacity. Always check the balance and pressure after a repair, but even if tests pass, prolonged high-speed use will accelerate aging. I recommend using repaired tires only for low-speed commuting and replacing them with new tires before long trips. Also, pay attention to the tire's age and wear condition—don't compromise safety to save money.
