You might not realize it, but your Pontiac may not be getting the best gas mileage you can get, and your tires may be to blame.

You see, your tires have a large impact on your gas mileage. If your tires aren't inflated correctly, you're going to lose gas mileage. Why is this? Well, it has to do with the way tires work.

The tires on your Pontiac are similar to a balloon. The more air that's inside the tire, the more firm and the more round your tire will be. If your tire is inflated to the recommended level, you might have six square inches of tire that touch the road when you're driving. If you remove just 5 psi from your tire, you may have as many as 8 square inches of tire touching the road. That means your engine has to work a little harder because there's more of your tire creating more friction on the road.

Some research suggests that proper inflation of your tires can gain you between three and four miles per gallon of gas. For the average car, that works out to be more than 1,500 extra miles you'll be able to drive each year, for free.

In addition, having tires that are properly inflated can help avoid tire blowouts and other accidents.
