The number is the pounds per square inch
The correct tire pressure is stamped on the tire,and is also located in your owners manual.You can purchase a digital tire pressure gauge to take the guess work out.
Read the vehicle data plate for tire pressures, and use a tire gauge to see if the tires are at that pressure.

manometer Commonly called a tire pressure gauge.
ANY tire gauge measures air pressure in PSI.
To measure air pressure.
A tire pressure gauge.
Gauge pressure is what you get when you take the reading from your tire pressure gauge. Absolute pressure is the pressure inside your tires plus the atmospheric pressure, which is roughly; 14.7 psi, 101.3 kPa (kilo-Pascals), or one atmosphere. Absolute pressure measures all of the pressure on your tires, inside and out, whereas gauge simply measures the pressure inside the tire.
