Can I drive on the highway after just patching a tire?

You can drive on the highway after just patching a tire. If the tire has been punctured and then patched, and it meets the safety requirements for tire repair with qualified operation procedures, it is safe for highway driving. Situations that require tire replacement before driving on the highway include: 1. The puncture wound is larger than six millimeters; 2. The same spot has been punctured multiple times and then patched; 3. The punctured area is on the tire sidewall; 4. The tire has been patched more than three times. Car tires are one of the important components of a vehicle, directly in contact with the road surface and working together with the car suspension to absorb shocks during driving, ensuring good ride comfort and smooth driving performance. They also ensure good adhesion between the wheels and the road surface, improving the car's traction, braking, and off-road capability, while bearing the weight of the vehicle.
I specifically asked an experienced auto repair master when I got my tire patched. Tires repaired with mushroom plugs or internal patches are completely safe for highway driving, as long as the repair is on the tire's crown area (the tread face) and the puncture doesn't exceed 6mm. However, if it's a temporary rope plug repair, you must never take it on the highway – those are only for emergency use. After patching, make sure the technician performs wheel balancing, otherwise you'll get severe steering wheel vibration at high speeds. Also, before long trips, check the patched area for bulges or air leaks – it's wise to drive in the city for a couple of days first to observe. If you hear abnormal tire noises or feel steering instability on the highway, immediately slow down and pull over to the emergency lane.
