How Many Years Can Tires Be Stored Without Use?
2 Answers
Tires have a storage lifespan, which should not exceed 3 years according to relevant regulations. Generally, tires should not be stored for more than 3 years from the date of production, and their maximum service life on vehicles should not exceed 8 years. Additional Information: 1. Tires are one of the key components of a vehicle, directly in contact with the road surface. Together with the vehicle's suspension system, they help absorb shocks during driving, ensuring a comfortable ride and smooth driving experience. They also maintain good traction between the wheels and the road, improving the vehicle's traction, braking, and off-road capabilities. Tires bear the weight of the vehicle, and their critical role in automotive performance is increasingly recognized. Tires hold a vital position among vehicle components, significantly impacting driving performance, and their lifespan directly affects transportation economic efficiency. 2. Car tires also have an 'age.' Even a brand-new tire will age if stored for more than four years, as the primary material of tires is rubber, which naturally deteriorates over time with use or storage. Using aged tires can mildly affect vehicle performance or, in severe cases, lead to blowouts, endangering lives.
I've been driving for twenty years, and experience tells me that tires stored for too long are definitely no good. For example, a few years ago, I had two new spare tires that weren't used and were stored for over five years. When I tried to install them later, I found the rubber had hardened and there were small cracks. The mechanic said five years is basically the safety limit, and it's best not to exceed six years. Storage conditions are crucial—sun exposure or high temperatures can accelerate aging. They should be kept in a cool, dry place, stored vertically to avoid deformation. Periodically rotate their position and check the surface. Beyond this time limit, grip deteriorates, and the risk of blowouts at high speeds increases, making them unsafe. So I've learned my lesson—use new tires as soon as possible after buying them or replace them regularly. Don't try to save a few bucks on this.
