Does Tire Patching Affect Driving on Highways?
1 Answers
After patching a car tire, it normally does not affect driving on highways. However, if the owner uses an external patching method, it is not recommended to drive on highways. The principle of external patching involves inserting a rubber strip into the tire. During high-speed driving, the tire pressure increases, which can easily cause the rubber strip to pop out, leading to a drop in tire pressure and potentially causing a traffic accident. If the owner uses an internal patching method, it is safe to drive on highways. It is also recommended to move the patched tire to the rear wheel of the vehicle, as the front wheels experience greater friction with the ground, which can damage the patched area. If the same spot on the tire has been patched multiple times, it is also not advisable to drive on highways, as repeated patching weakens that spot, and high-speed driving increases tire temperature, raising the risk of a blowout. Tires patched at authorized 4S shops can continue to be used. However, due to factors like patch quality or aging over time, air leakage may occur. If the driver unknowingly continues to drive at high speeds, prolonged underinflation can cause sidewall damage and eventual tire failure. Therefore, patched tires still pose some safety risks compared to intact tires. For highway driving safety, it is generally recommended to move patched tires to the rear wheels or use them as spare tires to minimize the adverse effects of compromised tire performance on highway safety.
