What Are the Reasons Why the Truck's Air Pressure Cannot Be Built Up?

[SanClara]

Truck's air pressure cannot be built up possibly due to the poor quality of the air pump, which results in insufficient pressure, making the inflation process very slow and laborious. It could also be caused by large cracks in the truck's wheels, leading to air leakage while inflating, making it impossible to build up pressure. If no solution is found, it is advisable to visit a repair shop. Below are factors to consider when adjusting tire pressure: 1. Seasonal factors: In winter, it is recommended to slightly increase the tire pressure by about 0.2bar based on the standard tire pressure. In summer, follow the lower limit of the standard tire pressure, and for vehicles parked outdoors, the pressure can generally be about 0.1bar lower than the standard to avoid tire blowouts due to high temperatures. 2. Road conditions: On roads with significant bumps, it is advisable to slightly reduce the tire pressure by 0.1-0.2bar from the standard. For roads with minor bumps, this can be ignored. For long-distance high-speed driving, the tire pressure should not be too low; it is recommended to slightly increase the pressure by about 0.2bar from the lower limit of the standard tire pressure.
