Air pressure is dependant on the vehicle NOT the tires. If you had a 1970's Jeep CJ 4 cylinder, it might only need 24-25 PSI. But if you had 1 1980's Blazer full size, it might need 35-41 PSI. And it could be that you try to put it on an Excursion (not actually possible, but for discussion sake only) and you couldn't safely put ENOUGH air in it!
Low pressure.
No -- Keep the same recommended air pressure in your tires at all times, but check and add air when the tires are cool and have not been running. Use a tire pressure gauge.
Eu sei
The recommended pressure that is printed on every tire.
34 PSI, but I the tires should have the suggested PSI written on the side of them.
temperature affects air pressure when it is cold air pressure decreases when it gets warm air pressures rises
When you drive, your tires get warmer, causing the air pressure within them to increase. Your tires can get warm after just 1 mile of driving. you should always check your tire inflation pressure when your tires are cold, and inflate them to the recommended pressure at that time.
32psi
In the winter, tires tend to loose capacity and shrink. Therefore making the air level decrease.
Different tires from different manufactures run at different pressures. On the sidewall, it should tell what the pressure should be for that particular tire.
Tires will have the maximum recommended air pressure embossed on the sidewalls of the tires themselves. The car manufacturer will have the recommended tire pressure on a label on the drivers door jamb and in the owners manual. This is what to set them at.
38 psi
