Tires impact your gas mileage in several ways. One of these.. your tire pressure. When tire pressure is low – especially more than 10 pounds less, it can greatly affect gas mileage. The U.S. Department of Energy says that for every 1 psi missing from your car's set of 4 tires, you lose 0.1 percent of your gas mileage. (Every psi lost also means that tires wear 10 percent faster.) If the driver ignores tire pressure for a month — tires naturally lose 1 PSI to 2 PSI per month. By properly inflating your tires, you can improve your gas mileage by 3.3 percent. And these days... every bit helps. Find a Mock-Beroth location near you at https://www.mockberothtire.com/Find-Us.
