About psi
PSI stands for 'Pounds per Square Inch'. It is the standard unit for pressure in the United States. It measures how many pounds of force are pressing on every square inch of surface. It is the unit every American driver looks for when filling their tires. psi are commonly used in Tire pressure (US), Blood pressure (rarely), Scuba tanks (US), and Industrial pumps, Paintball tanks.
A standard car tire is inflated to 30-35 psi.
About bar
The bar is a metric unit, but not an SI unit. It was created to be exactly 100,000 Pascals, which makes it very close to standard atmospheric pressure (1.013 bar). This 1-to-1 approximate relationship makes 'bar' very popular in diving, hydraulics, and tire gauges outside the US. bar are commonly used in Scuba diving, Espresso machines (9 bar!), Tire pressure (Europe), and Industrial hydraulics, Weather reports (mbar).
Car tires are often inflated to 2.2 bar.
