How to Adjust Air Pressure for Tire Performance

Air pressure is essential to optimal tire performance. Over and under inflated tires do not perform within their designed specifications. Over inflated tires can cause reduced vehicle maneuverability and loss of steering control. Under inflated tires can overheat due to tire stress and cause irregular tire tread. Both can lead to loss of control and automobile crashes. Adjust air pressure for tire performance as part of an auto maintenance program.

Difficulty: Easy

Instructions

1. Purchase a tire pressure gauge from any auto parts store.

2. Consult the tire placard for the recommended pounds per square inch, or psi. Tire psi can be found on the edge of the driver side door, the automobile manual or in the glove compartment box.

3. Check the air pressure while the tires are cold. Cold tires refer to tires that have not been driven for at least three hours.

4. Adjust the pressure in the tires by adding air according to the manufacturer's specifications.

Tips & Warnings

• Check tire pressure monthly and before embarking on any long distance road trips. Be sure to add air when necessary.
• Driving habits, road conditions and weather are factors that can affect tire performance.
• If your tires are over inflated, you can release some of the air pressure by pressing on the little metal stem of the air valve in the tires. Release a little air, then be sure to recheck the tire pressure to confirm that it's at the recommended psi.
• According to the Technology and Maintenance Council study, over 90 percent of tire failures are caused by under inflated tires.
