The easiest way to minimize fuel expenditure is to ensure that tires are inflated to the correct pressure. Statistics compiled by the American Automobile Association (AAA), show that fuel economy is compromised by 10 percent when tires are under-inflated by only 2 psi (pounds per square inch.) An under inflated tire increases rolling resistance, requiring your engine to work harder. Proper tire inflation could save several hundred dollars annually at the gas pumps.
