How Long Can a Spare Tire Last?
2 Answers
Replacing with a full-size spare tire can run over 100 kilometers without any problem, while a non-full-size one should not exceed 60 kilometers. However, it is still recommended to repair the tire as soon as possible, as the spare tire is only for temporary use. Relevant details are as follows: 1. Full-size spare tire: If the vehicle is equipped with a full-size spare tire, there are no restrictions on the driving distance or speed, because the full-size spare tire is the same size as the original tire, so there is no need to worry. 2. Non-full-size spare tire: There is also the non-full-size spare tire, which is now used in many vehicles. If it is such a non-full-size spare tire, there is no limit on the driving distance when using it, but there is a speed limit. Because it is not full-size, it is smaller than the original tire, so the maximum speed is 80KM/H.
I used to think the spare tire could last as long as a regular one, until I had a flat on the highway and switched to it. The car shook violently and felt out of control. After checking the manual, I learned that spare tires are only for temporary emergencies. Most manufacturers recommend driving no more than 50 miles at speeds below 50 mph, as they are smaller or made of thinner material with poor durability. Driving too far or too fast can cause rapid tread wear or even a blowout, damaging the rims or suspension. Since then, I only use the spare to reach the nearest repair shop and fix the main tire ASAP. Regularly checking the spare’s air pressure is also crucial to prevent leaks or aging from prolonged storage. Safety first—don’t cut corners. Replace the spare as soon as possible.
