How Long Can a Car Use a Spare Tire?
2 Answers
After replacing a tire with a spare, the duration of use varies depending on the type of spare tire. A full-size spare tire can run over 100 kilometers without issues, while a non-full-size spare should not exceed 60 kilometers. However, it is recommended to address the tire problem as soon as possible after switching to a spare, as it is only a temporary solution. Here are some details about car spare tires: 1. Spare tires are rubber products and will age over time even when stored: The aging cycle of a spare tire is 4 years, so it should be replaced every four years. 2. Spare tires are not suitable for long-term use: Spare tires are smaller and used less frequently, with different aspect ratios and widths compared to regular tires. After replacing a tire with a spare, the friction coefficients and ground adhesion of the four tires will differ, which can affect the vehicle's braking system if used for an extended period. 3. Spare tires should not be used for high-speed driving: Spare tires cannot match the performance of regular tires and require extra care. After switching to a spare, the driving speed should not exceed 80 km/h to avoid accidents.
About how long a spare tire can last after replacement, I'd say don't expect it to be a long-term solution. Last time my car had a flat and I put on the spare, I only drove about 80 kilometers before getting it fixed, because spare tires are designed for temporary emergency use. It's best not to exceed 80 kilometers per hour with a spare, as driving faster can make the car unstable and damage the suspension system. It's even more dangerous on highways, where sharp turns could lead to loss of control. My neighbor once used a spare tire for a long-distance trip and ended up with worn-out tires and costly repairs. So, after changing to a spare, head to a reliable repair shop for a new tire as soon as possible—safety first, after all, driving is no joke. Full-size spares are a bit more durable, but compact spares are even more fragile, so don't take risks.
