What is the reason for low tire pressure in one tire of a new car?

[VanRiley]

A new car having low tire pressure in one tire is caused by poor sealing performance of the tire. Here is a detailed introduction to adjusting car tire pressure: 1. Rough roads: On rough roads, it is appropriate to reduce the tire pressure by 0.1-0.2bar below the standard tire pressure. For long-distance high-speed driving, the tire pressure should not be too low; it is advisable to increase the tire pressure by about 0.2bar above the lower limit of the standard tire pressure. 2. New vs. old tires: For new tires, the tire pressure can be increased by about 0.2bar above the standard tire pressure. For old tires, it is appropriate to reduce the tire pressure according to the standard tire pressure, and if the wear is severe, follow the lower limit of the standard tire pressure. 3. Summer and winter: In winter, it is advisable to increase the tire pressure by about 0.2bar above the standard tire pressure. In summer, follow the lower limit of the standard tire pressure. If the car is parked outdoors in summer, the tire pressure can generally be about 0.1bar lower than the standard to avoid high-temperature blowouts.
