What is the service life of a car spare tire?

[DelEmiliano]

The service life of a car spare tire is 4 years. Since car spare tires are rubber products, prolonged storage can lead to performance degradation, manifested as hardening of the tire surface and even natural bursting of the outer tire. Generally, passenger cars are equipped with a spare tire, which has the same specifications as the original car tires. Methods for preserving car spare tires: 1. Regular inspection and cleaning: Tires stored for a long time will accumulate dust. Regularly check the air pressure and surface smoothness of the spare tire, and periodic cleaning helps preserve it; 2. Do not store oil products with the spare tire: Since spare tires are made of rubber, which can be eroded by various oil products, if the owner accidentally gets lubricating oil on the spare tire, it can cause swelling and erosion, reducing the spare tire's lifespan.
