Air up your tires. For every two PSI that all of your tires are below the recommended level, you lose 1% on your gas mileage. Most car tires are five to ten PSI below the normal level, so that means by just airing up your tires, you can improve your gas mileage by up to 5%. It’s easy, too. Just read your car’s manual to see what the recommended tire pressure is, then head to the gas station. Ask the attendant inside if they have a tire air gauge you can borrow (most of them do, both in urban and rural settings), then stop over by the air pump. Check your tires, then use the pump to fill them up to where they should be. It’s basically free gas!

That is a great tip not only for better gas milage but fo rsafety, too.
