How to Read a Car Pressure Gauge?

[StCassidy]

Connect the tire pressure gauge to the tire valve stem to check the car's tire pressure. The specific details for adjusting car tire pressure are as follows: Rough Roads: On rough roads, it's advisable to reduce the tire pressure by 0.1-0.2 bar below the standard tire pressure. For long-distance highway driving, the tire pressure should not be too low; instead, increase it by about 0.2 bar above the lower limit of the standard tire pressure. New vs. Old Tires: For new tires, the pressure can be increased by about 0.2 bar above the standard tire pressure. For old tires, it's appropriate to reduce the pressure according to the standard tire pressure, and if the tires are severely worn, use the lower limit of the standard tire pressure. Summer and Winter: In winter, it's advisable to increase the tire pressure by about 0.2 bar above the standard tire pressure. In summer, use the lower limit of the standard tire pressure. If the car is parked outdoors in summer, the pressure can generally be about 0.1 bar lower than the standard to prevent high-temperature blowouts.
