How Long Can a Car Spare Tire Last?
2 Answers
Car spare tires are divided into full-size spare tires and compact spare tires. Full-size spare tires can be used continuously without any issues, while compact spare tires should not exceed a speed of 60 kilometers per hour and can be driven for up to 100 kilometers. They are not suitable for long-term use. It is important to regularly inspect the spare tire to avoid discovering it is unusable when an emergency arises. Tires are circular elastic rubber products mounted on various vehicles or machinery, typically installed on metal rims. Car tires are one of the essential components of a vehicle, directly contacting the road surface. Together with the car suspension, they help absorb shocks during driving, ensuring good ride comfort, smooth driving, and strong adhesion between the wheels and the road.
I've been driving for over a decade, and let me tell you, a spare tire is just for temporary emergency use—it's not meant to replace your main tires for long-term driving. Typically, compact spare tires come with strict limitations: don't exceed 80 km/h, and you should replace it with a proper tire after driving about 50 to 100 km. Over time, the rubber in a spare tire stored in the trunk will degrade, leading to cracks or air leaks, usually needing replacement after around 5 years to avoid the risk of deflation or blowouts. Last time I used my spare, I noticed the tire pressure was low, making the car unstable and dangerous to drive. My advice? Check it regularly—press it when washing your car and measure the pressure—don’t wait until you need it to find out there’s a problem. Always prioritize safety: avoid speeding or long trips when driving on a spare.
