The U.S. Department of Energy has proven that under-inflated tires have a negative effect on your fuel economy. The department states that for every 1-psi drop in pressure, you can expect your gas mileage to lower by 0.4 percent.
Tires can lose about one to two psi per month through natural air loss from regular driving. You should check your tires’ pressure at least every month. In colder weather you can expect to lose one to two psi for every 10-degree drop in temperature.
In warm or cold weather, to get an accurate tire pressure reading, your vehicle has to have been parked for three hours or so. If you just pulled into a gas station to fill up, the rule of thumb is to subtract two or three psi from the reading due to the tires being warm.
Your tires’ manufacturer has set a maximum psi to insure your safety on the road and the longevity of their tires.
Therefore keeping your tires properly inflated is more important now than ever. Here are some options to help you keep your pressure;
