How Long Can a Spare Tire Last on a Car?

[OMargaret]

Spare tires typically last about 4 years. Here is some relevant information about spare tires: 1. A spare tire refers to the backup tire for a car, and its specifications are usually the same as the original car tire specifications. However, some vehicles use spare tires with special-colored rims, compact spares, foldable spares, or run-flat tires to remind the owner to inspect and replace faulty tires promptly. 2. Spare tires are actually for emergency use only and are not intended for long-term use. Regardless of width, manufacturers have specific production and usage requirements for spare tires. Since spare tires are not used regularly and do not experience wear, they differ from worn-out tires. Using a spare tire on a car inherently carries certain safety risks.
