How Often Should Car Tires Be Normally Replaced?

[MacTheo]

Car tires are normally replaced every 3 to 5 years, but it mainly depends on the condition of the tires. Generally, tires need to be replaced when fine cracks appear on the tire sidewalls, when the treads fall off, or when there are more than three patches on a tire. Tires are circular elastic rubber products mounted on various vehicles or machinery for rolling on the ground. They are usually installed on metal rims to support the vehicle body, cushion external impacts, ensure contact with the road surface, and maintain the vehicle's driving performance. Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and high or low temperatures during operation. Therefore, they must have high load-bearing capacity, traction performance, and cushioning properties.
