How Many Kilometers Can a Spare Tire Last?
2 Answers
Automobile non-full-size spare tires have a total mileage limit of no more than 50 kilometers. Full-size spare tires do not have a mileage limit. The following is the relevant content introduction: 1. The diameter and width of non-full-size spare tires are slightly smaller than the other four tires, so they can only be used as a temporary replacement and can only be used on non-driving wheels. The maximum speed should not exceed 80km/h, and the driving distance should not exceed 100km. Therefore, non-full-size spare tires cannot be used for a long time. 2. The specifications of full-size spare tires are exactly the same as the original four tires of the car, and they can replace any temporarily or already unusable tire. However, the cost is higher, and they should not be used for a long time either.
As a car enthusiast who frequently takes long road trips with my family, I have firsthand experience with spare tires. The typical range a spare tire can cover is between 80 to 100 kilometers, depending on the vehicle model and spare tire type. Once, when I had a flat tire in the countryside, I used a temporary spare (donut), which limited my speed to 60 km/h. I reached a repair shop within 80 km, where the mechanic explained that spare tires have thinner sidewalls. Prolonged driving can cause overheating and lead to blowouts, and may also affect the vehicle's suspension balance and handling stability, which is dangerous. As a result, I've developed the habit of checking my spare tire's pressure every six months to ensure it's maintained at the manufacturer's recommended level, typically around 35 psi. Spare tires are designed as emergency solutions, not permanent fixes, so after installation, you should drive at reduced speed and seek professional tire repair or replacement as soon as possible. Regular maintenance checks for wear, leaks, or cracks are also crucial. In short, spare tires are for safe transitions—never push their limits on long journeys.
