What does bar mean on a car?
1 Answers
Bar on a car is a commonly used unit for tire pressure, where 1 bar equals 100 kPa (kilopascal). Both bar and kPa are units of tire pressure commonly seen on vehicle tire pressure gauges. The standard tire pressure for most car wheels ranges between 2.2 bar and 2.5 bar. If a tire's pressure drops below 1.8 bar, it indicates air leakage and the vehicle should not be driven. In the absence of a pressure gauge after a tire pressure warning, you can visually inspect the contact area between the tire tread and the ground to determine which tire is low on air. If the air loss is not significant, the vehicle can still be driven, but the speed should not exceed 50 km/h.
