Tire wear rates differ depending on the axle on which the tires are fitted and whether the vehicle is front or rear wheel drive. To extend the life of your tires it is advisable to change tire positions on a regular basis. Different tire manufacturers may recommend different rotation periods, ranging from 3-5,000 km. It is advisable to switch tires from left to right periodically as well as from the back to the front of the vehicle. Certain high performance tires are position specific and should not be rotated. If in doubt, contact a specialist tire dealer.
