Tire pressures are measured in (Bar) or (PSI).
Read the tire sticker in the driver's door jam, or look at the tire, all pressure are measured when tires are cold.
Tire Pressure (measured cold): Front/Rear: 29 psi (200 kPa , 2.0 kgf/cm )
In the USA Tire pressure is measured in PSI (pounds per square inch) Most of the rest of the world measures it in KPA (kilo Pascal's)
AnswerTire pressure is supposed to be measured while the tire is cold. Tire pressure is higher when the tire is hot; therefore, the pressure of a hot tire will drop below its limit when it cools down.

Tire pressure is usually measured with a small bourdon-tube gauge that is calibrated accordingly, often in PSI, pounds per square inch. Sometimes the gauge is a linear spring loaded tube instead.
Tyre pressure is not measured in KG. It's like asking "what is the weight of my car in Meters?"
It really depends on a lot of factors. Once I had a 35psi tire "blow up" on 45 psi ... and it was the spare. (It didn't blow up - it sort of quietly disintegrated over a matter of about 10 minutes.) usually a tire is OK at twice its rated pressure - but remember, fast running and/or low pressure can cause quite a rise in the pressure of a tire. I've measured 75 in a 45 psi tire after a long run.
Tire pressure is related to what type of tire it is. the recommended pressure for the tire is on the side wall of the tire ========================================================== That is the MAXIMUM cold tire inflation pressure that is shown on the side of the tire
Air leaves a tire when the tire valve is open due to the pressure. The pressure outside of the tire is lower than the pressure inside the tire.
PSI (pounds per square inch) depending what part of the world you live in.
It could, some vehicles do have a tire pressure sensor in the spare.
