And some of the really inexpensive pressure gauges can be equally unreliable. You should be able to find a quality pressure gauge in an automotive or department store for about five dollars. This small investment will pay off in better and safer tire performance. Don't forget to rotate your tires. In addition to checking air pressure, you should have your tires rotated regularly so that they wear evenly.
Tires wear differently over time, depending on which corner of the car the tire is on.
How often you should rotate your tires varies with the type of car you have and how you drive it. To find out what's best for your vehicle, contact your auto dealer or mechanic. Driving carefully is another way you can help preserve the life of your tires. Avoid abrupt starts and stops. And, as much as possible, avoid potholes and other bumps in the road.
