Temporary, smaller-sized tires, often referred to as “space-saver” or “donut” spares, are designed for limited use following a flat tire. These spares differ significantly from standard tires in size, tread depth, and construction. They provide a temporary mobility solution, enabling a driver to reach a tire repair shop or safely return home. For instance, a compact spare might be significantly narrower than a standard tire and feature a shallower tread.
Utilizing a temporary spare ensures drivers are not stranded after a flat tire. This capability is crucial for safety and convenience, particularly in adverse weather conditions or remote locations. Historically, vehicles often carried full-size spare tires. However, advancements in tire technology, alongside efforts to reduce vehicle weight for improved fuel efficiency, have led to the more common adoption of space-saver spares. This shift emphasizes the importance of understanding the limitations of these temporary tires.
