Can new tires still be used after being stored for four or five years?

[JoshuaFitz]

Tires that have been idle for more than four years should not be used. This is because the rubber in tires deteriorates over four years of inactivity, leading to poor performance and an increased risk of accidents. The function of tires: Tires are circular elastic rubber products mounted on various vehicles or machinery to roll on the ground. They are typically installed on metal rims to support the vehicle body, absorb external shocks, ensure contact with the road surface, and maintain driving performance. Tire application scope and manufacturing requirements: Tires are often used under complex and demanding conditions. During operation, they endure various deformations, loads, forces, and temperature extremes. Therefore, they must possess high load-bearing capacity, traction performance, and shock absorption. Additionally, they need to exhibit high wear resistance, flexibility, and low rolling resistance with minimal heat generation.
