We know that proper air pressure is the most important thing you can do to help your tires wear longer, save fuel and improve the handling of your vehicle. Your tires will naturally lose one to two pounds of air pressure a month but most people don’t realize that for every ten-degree change in temperature, your tires’ air pressure changes one psi. Checking air pressure is easy with an accurate air gauge. beware of public pressure gauges. they’re often abused and may be unreliable.
The correct air pressure may be found in the vehicles’ owner’s manual or on the tire placard attached to the vehicle door edge, door post, glove box or fuel door. Remember, don’t use inflation numbers shown on the tire. this number only represents the maximum tire inflation pressure, not the recommended 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 a mile. driving on a tire increases its temperature and air pressure. To check air pressure, unscrew the valve cap and press the gauge into place. You may hear a short burst of air come out. the gauge will display the air pressure. If you add air, check the air pressure again, to make sure you have the correct air pressure. when finished, be sure to replace the valve cap. This will protect the valve stem from corrosion and debris, which could cause air loss. try to check your air pressure every other time you fill up at the gas station or at least once a month.
