If you want to get the most out of your set of tires before having to replace them, then you will want to perform regular rotations on them. The reason behind this is that since your tires take such a beating on the road and suffer from some of the worst wear and tear out of all of the components on your entire vehicle, you want to keep them in rotations to spread that wear and tear evenly over all four of them.
Most of the wear happens up front because not only are the front tires rotating as the vehicle moves forward, but that is also where your steering is done. So the left and right motion adds to that wear. By rotating them, you will find that the wear on the tread is done evenly, which is how it is designed. That even wear means that not one set wears out faster than the other, and you will get more life out of the set as a whole this way.
If your vehicle is ready for tire rotation or replacement, then bring it to our service department here at Porsche Bethesda today.
