Is the rotation speed different for non-full-size spare tires?
2 Answers
Non-full-size spare tires have different rotation speeds. Non-full-size tires are only for emergency use. Additionally, non-full-size tires have speed limitations and generally should not exceed 80 km/h. Full-size spare tires: Full-size spare tires are easier to understand—they have the same specifications as the car's four original tires, often even using the same wheel rims as the original tires. Non-full-size spare tires: Non-full-size spare tires are narrower in width or have smaller wheel rims. They usually come with steel rims and have speed restrictions (maximum speed should not exceed 80 km/h), serving only as a temporary replacement for the original tire.
As a seasoned driver with over a decade of experience, I must emphasize the importance of spare tire usage. Compact spare tires are indeed smaller, so when you drive at the same speed, they rotate faster due to their reduced size, requiring more revolutions. This isn't just a numbers game—uneven rotation speeds can make the car prone to skidding and unstable handling, especially dangerous during turns or on wet roads. Manufacturers typically specify speed limits, such as not exceeding 80 km/h, to prevent accidents. My advice is to avoid long-distance or highway driving immediately after switching to a spare tire. Prioritize visiting a repair shop to revert to the original tire and ensure the tire pressure meets standards—safety first is the golden rule.
