How many kilometers can a spare tire last approximately?

Replacing with a full-size spare tire can run over 100 kilometers without any issues, while a non-full-size one should not exceed 60 kilometers. Here is some information about tire usage: 1. When checking whether a tire meets the replacement standard, you can judge by the wear indicators on the tire. When the wear indicators in the tire grooves are level with the tire tread, it indicates that the tire's grip and drainage performance are very poor. In such cases, it is recommended to replace the tire. 2. Under long-term exposure to sunlight, ultraviolet rays and high temperatures can cause the rubber on the tire to harden and crack. After these problems occur, the elasticity of the rubber and its tensile resistance will sharply decrease. 3. The phenomenon of surface cracking and aging on tires generally occurs after more than 5 years, meaning that tires used for 5 years or more will have significantly reduced safety coefficients and comfort levels. At this point, the tires need to be replaced.
As someone with years of driving experience, I know that spare tires are only for temporary use. Spare tires are typically designed as an emergency solution, suitable for driving about 50 to 80 kilometers at most, with speed limited to below 80 km/h. Due to their smaller size and thinner tread, spare tires have less grip and don't match the performance of regular tires. Driving too fast or taking sharp turns can easily cause skidding, especially in rainy conditions or on mountain roads, increasing the risk of a blowout or rollover. I've seen cases where driving too far on a spare tire led to vehicle imbalance or even suspension damage. For safety, replace the spare tire with a regular one at a professional repair shop as soon as possible. Also, don’t forget to regularly check the spare tire’s pressure and condition in your garage to prevent aging or air leaks.
