How to read degrees on a weather barometer?

Reading the barometer is easy. Typically, barometers have two units, bar and kilopascal. 1bar=100kpa=1 atmosphere. Tire pressure is generally 2.5bar, which is 250kpa. 2.5bar is equal to 2.5 atmospheres.

As the only part of a car that is in contact with the ground, tires are crucial to driving safety and driving stability. Therefore, when using a car, always pay attention to whether the tire pressure is normal, and always check whether there is any obvious damage on the tire surface.

Tire pressure that is too high or too low has no effect. When the tire pressure is too low, driving at high speed can easily cause wavy deformation of the tire, increasing the probability of a puncture.

If the tire sidewall is punctured or scratched, it is recommended that the car owner not repair it. In this case, it is better to replace the tires with new ones.

The sidewall is a very fragile part. If the tire is continued to be used after the tire wall is repaired, there will be great safety risks.

It is recommended that car owners replace their tires every four years, even if the mileage is low within four years. Tires are rubber products and will age over time.

When buying new tires, you should also check the production date of the tires. If it was produced a long time ago, don't buy it either. Even if tires are not used, they will age. The production date of a tire is generally represented by a four-digit number and written on the side of the tire. For example, 1019 means that the tires were produced in the 10th week of 2019.
