44 Checking Tire Pressure For Better Gas Mileage – Tireamerica

How Tire Pressure Impacts Your Gas Mileage

From tire pressure to gas mileage

While your tires and gas tank are located in very separate areas of your car, they’re more closely connected than you’d think. The fact is your tire pressure has a very definite – not to mention important effect on your gas mileage.

Tire pressure, seasons and gas mileage

Cars typically get better gas mileage during the increasingly hot summer months, as opposed to the long cold winter ones. Underinflated tires can reduce gas mileage by about .02% for every 1psi decrease. For example, a 10-degree drop in temperature can cause a 1psi drop in air pressure. This is particularly important in winter months, when the air pressure in your tires drops right along with the air temperature outside.

Millions of families drive much longer distances due to vacation traveling during summer months. To prepare for those longer road trips, it’s a good idea to have your cars serviced at that time to get better gas mileage during the hotter months.

From tire inflation to fuel cost deflation

So there you have it: Tires that are optimally inflated can save you money at the gas pump. The U.S. Department of Energy says the optimal tire pressure level will increase your gas mileage by over 3% in any season, which comes out to about 12 cents a gallon. Do the math and you’ll see that, ultimately, the proper tire pressure can save the average consumer up to $94.00 a year and take some pressure off your budget.
