How Long Can Unused Tires Be Stored?

[Terry]

If car tires are not in use, they can generally be stored for about four years, with a maximum of five years, to avoid safety hazards caused by internal aging when used later. Precautions for using tires: Pay attention to tire pressure: Air pressure is the most critical factor affecting tires. Both too high and too low pressure will shorten their lifespan. Insufficient pressure increases tire body deformation, leading to cracks on the sidewalls; excessive pressure causes excessive stretching of the tire cords, reducing elasticity and shortening the lifespan. Regularly check front-wheel alignment: Front-wheel alignment significantly impacts tire lifespan, especially toe-in and camber angles. Excessive camber accelerates shoulder wear (uneven wear), while incorrect toe-in mainly accelerates wear on the inner or outer edges of the tire. Limit driving speed: Frequent high-speed driving significantly reduces tire lifespan. At higher speeds, tires make more contact with the ground per unit time, increasing friction and deformation frequency. This intensifies circumferential and lateral distortion of the tire body, further shortening its lifespan.
