Temporary, compact spare tires, often called “donuts” or “space-savers,” are designed for short-term, emergency use following a flat tire. These spares differ significantly from full-size tires in their construction, tread depth, and speed limitations. Full-size matching spares, while less common due to space and weight considerations, offer the same performance characteristics as the vehicle’s regular tires.
Maintaining mobility after a tire failure is essential for safety and convenience. A spare tire allows drivers to reach a repair facility or safely navigate to a location where a full-size replacement can be installed. The development of spare tires reflects the automotive industry’s ongoing focus on driver safety and vehicle dependability. While early motoring often required arduous roadside repairs, the spare tire provides a convenient and relatively quick solution for resuming travel.
