After how many kilometers does a motorcycle rear tire need to be replaced?

A motorcycle rear tire generally needs to be replaced after traveling 80,000 kilometers. Basic introduction to tires: Tires are circular elastic rubber products mounted on various vehicles or machinery to roll on the ground. They are usually installed on metal rims to support the vehicle body, absorb external shocks, ensure contact with the road surface, and maintain driving performance. Tires are often used under complex and harsh conditions, enduring various deformations, loads, forces, and extreme temperatures during operation. Therefore, they must possess high load-bearing capacity, traction performance, and shock absorption. At the same time, they must also exhibit high wear resistance and flexibility, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production, highlighting the significant demand for rubber in tire manufacturing. Precautions for tire maintenance: Maintain a safe distance when driving at high speeds to avoid unnecessary or frequent braking, which can damage the tires. For safety reasons, pay attention to the tread depth of the tires. Worn-out tires reduce friction with the road surface, leading to longer braking distances, so avoid high-speed driving. There is a direct relationship between tire load and pressure. Overloading is similar to low tire pressure and can cause tire damage. Frequent overloading can reduce tire lifespan by 20% to 50%. Incorrect loading methods can also lead to uneven tire load distribution, causing excessive wear on certain tires and shortening their lifespan. Tire pressure is crucial. The inflation pressure must comply with national standards for different types and specifications of tires. Regularly check tire pressure, as both overinflation and underinflation can lead to irregular wear, tread groove cracking, cord breakage, ply separation, and tire blowouts. If driving continuously at high speeds, the pressure should be increased by 5% to 10% above the standard pressure. Additionally, tire pressure rises due to temperature increases after driving, and air should not be released at this time.
