LOWER TEMPERATURES CAUSE LOWER TIRE PRESSURE

This news bulletin informs motorists that a car's tire pressure decreases as the temperature drops -- about one pound per square inch for each 10 degree Farenheit drop in temperature. Motorists are advised to check tire pressure often and only when the tires are cold. It is also pointed out that mud and snow (M/S) tires require four more pounds of pressure than regular tires, and that it is a misconception to think that lower tire pressure improves traction in the snow. Steps motorists should take to prepare their tires for colder weather driving are listed.
