You've probably never paid much attention to the writing on the sides of your tires, but they contain a wealth of information. There's a long combination of letters and numbers that can tell you a whole lot about what tires your vehicle was designed to be riding on. Let's check out this example found on an SUV: P245/70R17 108T. The first letter, P, means it's intended for passenger vehicles. If there's no letter, it means it's a metric tire. If there's an LT at the beginning or end that means a tire designed for light trucks. Moving on to our example, the 245 shows how wide the tire is in millimeters from sidewall to sidewall. The number that follows in our example, 70, means the height of the tire is 70% of its width. The letter after that in our example, R, describes the type of tire (on this vehicle, radial). Following that is the diameter in inches, in our SUV example, 17 inches. How much load the tires' sidewalls are designed to take ... read more

If someone told you there was a fairly inexpensive way to improve your vehicle's handling, fuel economy and extend the life of your tires, you'd probably ask, "What do I have to do?" The answer is to rotate your tires. But you have to do it regularly. A lot of drivers think skipping tire rotation is a way to save money. But when you don't rotate your tires, they will almost certainly wear unevenly. That's because when your tires touch the surface of the road, the friction and traction causes miniscule parts of the rubber to come off. And that process isn't exactly the same on each corner of your vehicle. Some vehicles have the drive wheels in the front, some in the rear and some on all wheels. Rotating your tires at regular intervals minimizes the differences in the way the tires wear. The amount and pattern will be spread out equally if your tires spend time at all different positions. The more even the wear, the more consistent traction, hand ... read more
