Tire Air Pressure
Keep Tires Properly Inflated
One of the most important (and cheapest) changes you can make to improve your mileage is to keep your tires inflated at the highest recommended level. By looking in your vehicle owners manual you will find a range of tire inflation pressures that can be used based on load conditions. Tire inflation pressure is determined by taking into consideration comfort and safety.
You can also read the information on the sidewall of your tires regarding the maximum safe inflation pressure. While you are looking at your tires keep an eye on uneven tire wear. Greater tread wear in the center means too much pressure. You can save as much as 10 cents per gallon with properly inflated tires. When your tires aren't inflated properly it's like driving with the parking brake on.
