Can I Drive on the Highway After a Tire Repair?

Yes, you can drive on the highway after a tire repair. A repaired car tire is functionally equivalent to its original state and meets the driving conditions required for highways. A tire is a circular elastic rubber product mounted on various vehicles or machinery, designed to roll on the ground. Typically installed on metal rims, it supports the vehicle body, absorbs external shocks, maintains contact with the road surface, and ensures driving performance. Highways should clearly indicate the speed limits for each lane, where the maximum speed must not exceed 120 km/h, and the minimum speed should not be below 60 km/h. On highways, the speed of small passenger vehicles must not exceed 120 km/h, other motor vehicles must not exceed 100 km/h, and motorcycles must not exceed 80 km/h.
I just went through this. I had a nail in my left front tire and got it repaired at a repair shop using a mushroom plug. I drove for a week with normal tire pressure monitoring before daring to take the highway. There are three key points to consider when driving on the highway after a tire repair: first, the type of patch—mushroom plugs or vulcanized hot patches are the most reliable; second, the location of the tire damage—never take chances if the sidewall is damaged; third, the standard of the repair work—it’s essential to have a professional shop apply sealant to the tire. For example, I drove over 300 kilometers from Nanjing to Hangzhou at 120 km/h the whole way, and even checked the tire temperature and pressure at the service area—everything was completely fine. However, remember that a repaired tire is best not placed on the drive or steering wheels; swapping it to the rear wheel is safer.
As someone who frequently drives long distances, it depends on how the tire was repaired. Temporary plug repairs using rubber strips can only last for a few dozen kilometers before needing a proper repair shop—it's too risky for highways. However, a professional hot patch repair done by a tire shop, where the tire is dismounted and the inner wall is buffed, is extremely durable. I've had tires repaired three times and still driven on highways—the key is ensuring the tread damage diameter doesn’t exceed 6mm. Also, always get a wheel balance after the repair! Last time I skipped it, the steering wheel shook badly. Before a long trip, make sure your spare tire is fully inflated—just in case the repair fails, it can hold up for a while.
