How to know the wear level of Petrol Car tires?

Generally speaking, the service life of Petrol Car tires in normal use is 4 to 5 years. After 5 years, even if the tread wear is very small, it is easy to replace it, because the rubber in the tread will age over time, and there will be many small cracks. This is what causes a tire blowout.

However, relevant national departments have not yet made special regulations on the shelf life of Petrol Car tires, because the service life of Petrol Car tires will vary depending on the rubber formula of Petrol Car tires, the vehicle environment and driving habits. Therefore, we need to pay more attention when driving. There are also signs of tire aging on Roewe Car. For example, the aging parts of the tread mostly appear from the edge parts such as the tire side or shoulder. Long-term exposure to the sun and rain will cause small circles of cracks to appear on the rubber surface. These cracks indicate the load-bearing capacity and load-bearing capacity of the Petrol Car tires at this time. The quality has begun to decline, so it is best to replace them in advance to reduce the risk of puncture.
In addition to aging, Petrol Car tires also wear out naturally. Therefore, genuine Petrol Car tires will have wear limits marked on the sidewalls before leaving the factory to indicate the real-time wear status of this Petrol Car tire. For gasoline tires without wear marks, we can also use calipers to measure them. Generally, gasoline tires with groove depths less than 1.6 mm can no longer be used, because at this time, the drainage performance and puncture resistance of gasoline tires will deteriorate. dramatically drop. In addition, if a Petrol Car tire has been repaired three or four times, we recommend that you change the Petrol Car tire to a non-driving wheel or rear wheel to reduce the risk of puncture.
Of course, the life of Petrol Car tires also has a lot to do with whether they are used normally. First of all, we must ensure that the tires of Roewe Car are always under normal tire pressure. Too low or too high tire pressure of Roewe Car will cause hidden dangers to the safety of Petrol Car tires. I need to remind everyone not to believe what you see with your eyes, because most cars are now equipped with tubeless low-pressure radial gasoline tires. Sometimes they look a bit flat from the outside, but it does not mean that they are definitely inflated. Professionals A tire pressure instrument is the only way to check the tire pressure of a Petrol Car. In addition, the tire pressure must be measured on cold tires. If the tire pressure is measured on hot tires, the measured value must be subtracted by 0.3 PA to be accurate.
