Can a Full-Size Spare Tire Be Used as a Regular Tire?

[DiHope]

Full-size spare tires cannot be used as regular tires. Even if the size is identical, a full-size spare tire can only be used as an emergency tire. Below is relevant information about car spare tires: 1. Concept of Spare Tires: A spare tire refers to a backup tire for a car, with specifications matching those of the original car tires. However, some vehicles use special-colored rim spare tires, compact spare tires, folding spare tires, or run-flat tires to remind owners to promptly inspect and replace faulty tires. 2. Types of Spare Tires: There are three types of spare tires: full-size spare tires, non-full-size spare tires, and run-flat tires. Full-size spare tires have identical specifications to the other four tires on the vehicle and can replace any temporarily or permanently unusable tire. Non-full-size spare tires have slightly smaller diameters and widths compared to the other four tires, making them suitable only for temporary use and exclusively for non-drive wheels. Run-flat tires, also known as safety tires or colloquially as "anti-blowout tires," are directly translated in the industry as "tires that maintain functionality when deflated."
