Quote: I get my tire pressure checked whenever I get my oil changed, about every 3000 miles. I'm not sure why having the correct tire pressure would help gas mileage, but I've heard from several different sources that it does...
Well, the thing is that when the tires have lower pressure and touch more surface because they lack air, then the car needs more energy to move, therefore needs more gas. The same happens on the bike. If you ride with low air on the tires, it is a lot harder than if the tires are well inflated.
