What is a non-full-size spare tire?

[StEmilio]

Non-full-size spare tire refers to a spare tire that is slightly smaller in diameter and narrower in width than the regular tires. Below is extended information about the differences between full-size and non-full-size spare tires: 1. Size: A full-size spare tire has the same specifications as the four original tires on the car, usually with the same rim as the original wheels. A non-full-size spare tire is narrower in width or has a smaller rim size, typically using a steel rim. 2. Driving speed: Non-full-size spare tires have speed restrictions (maximum speed cannot exceed 80 km/h) and can only temporarily replace the original tire. Full-size spare tires have no such restrictions. 3. Weight: Full-size spare tires, which have the same specifications as the four original tires, are much heavier than non-full-size spare tires.
