Can a patched car tire still be used on highways? Even if the tire has been damaged and requires repair, it generally does not significantly affect the vehicle's driving performance. The functions of a tire are: 1. To transmit driving force, braking force, and steering force to enable vehicle operation; 2. To support the vehicle's load; 3. To reduce and absorb vibrations and impacts during driving, preventing severe vibrations from damaging vehicle components. Methods for tire maintenance include: 1. Regularly clean stones stuck in the tire treads; 2. Minimize exposure to direct sunlight; 3. Monitor tire pressure promptly; 4. Pay attention to suspension maintenance; 5. Regularly check front wheel alignment; 6. Adopt careful driving habits, choosing smooth road surfaces and avoiding objects that could puncture or scratch the tires, as well as chemical spills that could corrode the tires.
As a driver who frequently travels on highways, I believe whether a repaired car tire can be used on highways depends on the quality and location of the repair. If it's a professional mushroom plug repair in the middle of the tread, it's generally not a big issue. I've driven on highways with repaired tires before, but you must ensure the tire itself is in good condition without aging cracks, and after the repair, a wheel balance should be done to avoid shaking while driving. At high speeds, the tire heats up, and the repaired area might not withstand the high pressure, posing risks of detachment or blowout. So, my advice is, if you must drive on highways, try not to exceed the speed limit too much, avoid long-distance trips, and regularly check tire pressure and wear. Safety always comes first. If the puncture is on the sidewall edge or the repair is improper, I would never take it on the highway—I'd rather replace it with a new tire.
From a technical perspective, tire repair methods include plugging, patching, and mushroom plugs. Professionally repaired tires with central tread damage can generally be used on highways. However, high-speed driving increases tire pressure and uneven wear, making the repair point a potential weak spot. My view is that after repair, it's best to test the tire by driving at low speeds for several dozen kilometers to ensure there's no abnormal heat or vibration. Older repaired tires carry higher risks, especially those that have been used for several years or are nearly worn out. Checking tire pressure before highway driving is crucial, keeping it within the recommended range. Sidewall repairs are absolutely unsafe as they can easily split at high speeds, leading to loss of control. Tires repaired multiple times should also be avoided. In short, finding a reliable repair shop is essential. After tire repairs, I only drive on suburban highways, avoiding mountainous areas and long-distance trips.
