AskPatty’s Tips to #Green Your Car and Save Gas: Maintain the Correct Tire Pressure
Proper tire pressure can improve gas mileage by 3%.
Getting more mileage from each gallon can save you as much as 10 cents per gallon at today's gas prices: That's a savings of $30 to $70 depending on how much you drive, and can reduce greenhouse gasses by 1.42% to 0.69%. Low tire pressure increases your car's rolling resistance and forces your engine to work harder.
Invest in an inexpensive tire gauge and check your tire pressure monthly and before long trips or when transporting heavy items. The correct tire pressure for most cars can be found in the driver's side door jamb or the owner's manual. Properly inflated tires will also last longer, which is good for both the environment and your wallet.
