When should the original tires be replaced?

[DiChase]

Original tires are generally recommended to be replaced after driving 60,000 to 80,000 kilometers. However, some cars may have been driven for 3 to 4 years and traveled hundreds of thousands of kilometers, yet the tread patterns on the tires are still deep. Whether to replace them or not requires a tire inspection, as the decision to replace tires depends on various road conditions and specific circumstances. Tires are circular elastic rubber products mounted on metal rims, designed to roll on the ground and fitted to various vehicles or machinery. They support the vehicle body, absorb external shocks, ensure contact with the road surface, and maintain driving performance. Tires are often used under complex and demanding conditions, enduring various deformations, loads, pressures, and high or low temperatures during operation. Therefore, they must possess high load-bearing capacity, traction performance, and shock absorption capabilities.
