In fact, whether it is a family car or an operating vehicle, how often a car tire needs to be filled is not judged based on time, but based on the tire pressure value of the car tire to determine whether the tire needs to be inflated.It is not that the tire must be inflated once a month or two. What the owner needs to do is to check the air pressure value of the tire within a certain period of time to determine whether it needs to be inflated and pressurized.

Moreover, most family cars now have tire pressure alarm systems. If the tire pressure is normal and the alarm system is not on, then basically the tires are not out of air and there is no need to inflate.However, if the tire pressure warning sounds, the owner needs to check whether the tire pressure is too high or the tire pressure is too low. At this time, you can view the accurate tire pressure value from the car's central control screen. If the tire pressure value is shown to be too low, the owner needs to inflate and replenish the pressure in time.

Although car owners know that car tires need to be filled in time, they don't know how much tire inflation is appropriate.Under normal circumstances, the tire pressure of automobile tires is generally controlled in the range of 230 kPa to 250 kPa, but due to different models, the corresponding standard tire pressure values will be different.

Therefore, the owner can refer to the tire pressure values on the B-pillar and C-pillar of the car door, so that the car tires can be more accurately pressurized. After all, the tire pressure values of the four wheels of most cars are slightly different.If the car owner does not find the tire pressure value as mentioned above when he is pumping, he can also directly observe the value on the tire pressure device and control it within the range of 230 to 250 kPa.
