It is important to check your tyres and wheels for signs of possible damage, and check your vehicle for any mechanical problems and correct if necessary. If you notice irregular or uneven tread wear, the tyres should be rotated to alleviate the problem.

You should follow the rotation pattern or procedure indicated in your limited warranty and the vehicle owner’s manual. We recommend you rotate tyres on front wheel drive vehicles and/or all season tyres on any vehicle every 12,000 km to equalize the rate of wear; however, rotate your tyres earlier if signs of irregular or uneven tyre wear arise, and have the vehicle checked by a qualified technician to determine the cause of the wear condition. The first rotation is the most important.
