Wheel alignment and balancing are important for safety, comfort and maximum mileage from your tires. Inspect your tires at least once a month for signs of unbalance, uneven wear or damage (ie. cuts, cracks, splits, penetrations, bulges, and impacts.)
Uneven wear patterns may be caused by incorrect inflation pressure, misalignment, imbalance or suspension neglect. If not corrected, further tire damage will occur. These conditions shorten the life of your tires and may result in loss of vehicle control and serious personal injury.
You should have your alignment checked periodically as specified by the vehicle owner's manual or whenever you have an indication of trouble such as pulling or vibration. Wheel alignment costs may be different based on local dealer costs.
Cooper also recommend rotating tires every 5,000 miles to prevent tread from wearing out and keep the tread even with the other tires, thus preventing vibrations.
