Correct Tire Inflation Improves Fuel Economy
Checking your tires air pressure on a regular basis can help save you money in the long run at the gas pump.
Properly inflated tires can increase your fuel efficiency, while underinflated tires decrease your fuel efficiency and can result in extra time and money at the gas station.
Your tires lose air pressure each month due to weather changes and normal use, typically about 2-3 psi. Underinflated tires reduce fuel economy by creating extra resistance as they roll down the road. This resistance makes the engine work harder to power the car, burning more fuel in the process.
A recent RMA survey revealed that only 17% of vehicles on the road had all four tires properly inflated. The Department of Energy maintains that underinflated tires can decrease fuel efficiency by 0.4% for every 1 PSI drop in the pressure of all four tires. Use our tire pressure / gas mileage calculator to determine how much you can save through regular air pressure checks.
In addition to regular air checks, you can also maintain your fuel efficiency by practicing responsible driving habits. Driving sensibly helps you decrease fuel consumption, while aggressive starts and stops use more fuel. The Department of Energy explains that gas usage increases significantly as you exceed 60 MPH, so maintain fuel efficiency by choosing a safe cruising speed.
