Here are two key tire factors that affect vehicle fuel efficiency:
Proper inflationIf your tires are underinflated, you reduce your vehicle's fuel economy and increase the amount of greenhouse gases and other pollutants it puts into the air.
Keeping your tires properly inflated can save you up to 11 cents per gallon. If you fuel up once a week, those savings add up fast.
- To save on gas, check your tire pressure once a month.
- Keep a tire pressure gauge in your vehicle, because hitting a pothole or a curb can cause a significant loss in tire pressure that you may want to check on at any time.
- Make sure you know the recommended pressure for you tires: It's in your owner's manual or the Tire and Loading Information Label located on the driver's side door edge or post.
- Check your tires when they're "cold," which means that they haven't been driven on for at least three hours.
Rolling resistance refers to the amount of fuel needed to roll your tire down the road. Using tires with low rolling resistance increases your vehicle's fuel efficiency.
- When it's time to buy new tires, research which low rolling resistance tires are recommended for your vehicle.
- Choose fuel-efficient, low rolling resistance tires to help improve your fuel efficiency.
