Frequently Asked Questions

What is 1 bar in PSI?

1 bar = 14.5038 PSI. Atmospheric pressure is about 1 bar = 14.7 PSI.

What tyre pressure should I use?

Most cars recommend 30–35 PSI (2.1–2.4 bar). Check your vehicle manual or door jamb label. Under-inflation wastes fuel and generates heat.

Are bar and atmosphere the same?

Close: 1 bar = 100,000 Pa; 1 atm = 101,325 Pa. The difference is small (about 1%) for practical purposes.
