Check your tire pressure once a month after you fuel your vehicle

According to studies by the National Highway Traffic Safety Administration (NHSTA) on tire related crashes, the leading cause of tire failure is under inflation. Under inflation can have many causes, including a gradual loss of pressure through membranes in the tire itself. It is typical for pressure to drop approximately 1 pound of air per month and 1 pound of air for each 8-degree loss in outside temperature.

Under inflation has immediate effects on vehicle handling (as well as fuel consumption), but its potential impact on overall safety and tire life are even greater. It results in premature and uneven tread wear on the outer edges. Under inflation also increases stress on the tire carcass itself, through flexing and overheating, which can lead to structural failures such as tread separation.

That's why it is imperative to check and adjust tire pressure at least once a month and before every long trip (over 250 miles). Recommended pressures are printed on a label located on the driver's doorframe or in the glove box. These statistics relate to compressed air and once you use nitrogen this enhances the life of your tires and handling as well as slows the process down for air loss.
