Your Tires ' One way to stretch your travel budget this summer is to get more miles to the gallon by keeping your tires properly inflated, says the Tire Industry Safety Council. To ensure you're getting the best mileage possible while on the road, the Council advises that you check your tires at least once a month, or about every other time you buy gas. This is particularly important advice for motorists using self-service gas stations where professional vehicle and tire servicing is often limited or not available.
Underinflated tires have higher rolling resistance.
In addition to the bonus of extra miles per gallon, properly inflated tires help ensure safety and optimum treadwear. The Council Chairman adds that the proper tire inflation pressure for your vehicle is listed on a placard, located on the glove or fuel compartment door or driver's side doorpost. It is also listed in the vehicle owner's manual. Under normal loads, inflate tires according to the vehicle manufacturer's recommendations, not the maximum pressure listed on the sidewall. You should never exceed this maximum pressure.
