Can a spare tire that hasn't been used for ten years still be used?

[BrantleyRose]

A spare tire that hasn't been used for ten years cannot be used. A car's spare tire is not suitable for long-term use. Although it hasn't reached a certain mileage, the spare tire, like regular tires, is a rubber product with a limited shelf life, typically 3 to 5 years. Car tires are one of the important components of a vehicle, directly in contact with the road surface. Together with the car's suspension, they help absorb shocks during driving, ensuring good ride comfort and smooth driving. They also ensure good adhesion between the wheels and the road surface, thereby improving the car's traction, braking, and off-road capability. Additionally, they must have high wear resistance and flex resistance, as well as low rolling resistance and heat generation.
