Correct Tire Inflation Improves Fuel Economy

Regularly checking your tires’ air pressure 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 study revealed that only 17% of vehicles on the road had all four tires properly inflated. The Department of Energy has found 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 regularly checking your tire pressure, 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 miles per hour, so maintain fuel efficiency by choosing a safe cruising speed.
