The general service life of tires is about 3 years and 8W kilometers.

This is not absolute, because the wear and tear of tires has a great relationship with the road surface. If the road is flat, the service life will be long. If the road is bumpy or gravel, the service life of the tire will definitely be reduced.

The tire is a ring-shaped elastic rubber product that is assembled on various vehicles or machinery and rolls on the ground. Usually installed on a metal rim, it can support the car body, cushion the external impact, achieve contact with the road and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. They are subjected to various deformations, loads, forces, and high and low temperature effects during driving. Therefore, they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it also requires high wear resistance and flex resistance, as well as low rolling resistance and heat build-up.

The role of tires:

Raven:

1. The tire is the carrier of force transmission between the vehicle and the road surface. Through the tire, the driving force, braking force, steering force, etc. are transmitted, so as to realize the driving, braking, steering and other operations of the car.

2. Support vehicle load. The load of the vehicle causes the tire to sink until the average pressure of the tire contact area and the inflation pressure inside the tire balance.

Raven:

3. Reduce and absorb the vibration and impact force during the driving process of the car, and prevent the car parts from being violently shaken and cause early damage. At the same time, it adapts to the high-speed driving state of the vehicle and reduces driving noise, ensuring driving safety, comfort, handling stability and fuel economy.

Normal use of tires:

1. Check the inflation pressure of the tires from time to time

Since the normal tire pressure can effectively improve the fuel economy of the vehicle, the tire inflation pressure should be checked from time to time.

Raven:

When the inflation pressure of the tire is too low, on the one hand, it will cause the tire rigidity to decrease, the sidewall deformation area will be excessively deformed, and the tire rolling resistance will increase, resulting in an increase in fuel consumption; on the other hand, excessive sidewall deformation will cause the tire and the ground excessively The friction and heat will cause excessive wear of the two shoulders of the tire, tearing of the sidewall, easy damage to the tire spigot, easy delamination or cracking of the sidewall, and easy off-ring of the tire.

Raven:

In addition, too high inflation pressure will also cause tire crown center wear to occur too fast, the tread is easy to be padded or punctured, tread bottom groove laceration, tire deformation and other failures, especially when driving at high speed for a long time due to tires and The friction on the ground generates heat, so that the air in the tires has no room to expand, and there is no risk of tire blowouts, which endangers life and safety.

Raven:

2. Inspect the tires by visual inspection

We can also check by visual inspection, but visual inspection requires experience to a certain extent and the accuracy is low. It can be checked with a tire pressure gauge and is more accurate. Or ask the service station personnel to inspect and remove foreign objects in the tire grooves during regular maintenance of the vehicle to avoid damage to the tires due to foreign objects. And check whether the tire tread depth exceeds the use limit, if it exceeds the limit, it should be replaced in time to avoid danger.

Raven:

3. Always pay attention to the load of tires

When we pay attention to the tire pressure, we should also pay attention to the load of the tire, because the tire is the final component that bears the load of the vehicle. The structure, strength, and operating pressure and speed of the tire are determined by the manufacturer's strict calculations. If the tire does not comply with the standard and is overloaded, its service life will be affected.
