What does bar mean?

[AnnieLynn]

bar is a unit of tire pressure. If the car displays low tire pressure on the bar gauge, the following solutions can be considered: Air leakage issue: Check if there is any air leakage in the tire. If found, immediately proceed to patch or replace the tire. If unsure about air leakage, inflate the tire first and observe if the pressure normalizes. If the 'bar' warning on the dashboard disappears after restarting the engine, it indicates the issue has been resolved. Tire pressure issue: Tire pressure should neither be too high nor too low. Low pressure can cause wave-like deformation during high-speed driving, increasing the risk of a blowout and reducing the tire's lifespan. Conversely, excessive pressure reduces the contact area between the tire and the road, adversely affecting the car's stability.
