Can a spare tire be used on the highway?

[VanRosalie]

Spare tires can be used on the highway. The details of various spare tires are as follows: 1. Full-size spare tires have no restrictions on mileage or speed and can replace any tire that is temporarily or permanently unusable. 2. Non-full-size spare tires can only be used on non-driving wheels, and the maximum speed should not exceed 80km/h. This is because the diameter and width of such spare tires are slightly smaller than the other four tires, making them suitable only for temporary replacement. 3. Run-flat tires (commonly known as "anti-blowout tires") do not lose air or lose air very slowly when punctured. They can maintain their driving profile, and the tire bead remains fixed on the rim, ensuring the car can drive to a service station for a long time or temporarily stable.
