Maintaining proper air pressure is the most important thing you can do to help you get the most out of your tires. Proper air pressure can help your tires wear longer, save fuel and improve the handling of your vehicle.

Your Tires will naturally lose 1 to 2lbs of air pressure every month but what most people don't realize is that with every 10 degree change in temperature your tires air pressure changes 1psi.

Checking Air Pressure is easy with an accurate air gauge. Beware of public air pressure gauges they are often overused and may be unreliable.

Your vehicles correct air pressure may be found in the vehicles owners manual, or on the tire placard located in the vehicle door jam, glove box or behind the gas tank door.

Remember not to use the inflation numbers located on the tire's sidewall. This number indicates the maximum pressure the tire can handle and NOT that optimal air pressure for your vehicle.

To get the most accurate reading make sure to check the pressure before driving on your tires. If you have to drive before you check the pressure try not to drive more than 1 mile, driving on a tire increases temperature and air pressure.

To check your air pressure:
1. Locate the proper air pressure settings for your vehicle. The recommended air pressure often differs from front to rear.
2. Unscrew the valve cap.
2. Press the air pressure gauge and look at the reading, reset the air pressure gauge and check it again to ensure an accurate reading. repeat until an consistent reading has been confirmed.
3. Adjust the air pressure up or down as needed.
4. Recheck air pressure after adjustments have been made.
5. When finished, replace valve cap .

To get the most out of your tires be sure to check your tire air pressure every other gas fill up or at least once each month.

Finally, don't forget to check your spare tire. Many spare tires require a higher amount of air pressure to carry the load of your vehicle.
