The most common cause of uneven tire wear is a wheel alignment problem. The fix could be as simple as getting the car realigned or it may involve replacing steering/suspension components prior to performing an alignment. Tire pressure is also a common cause of tire wear. If the air pressure is too high inside the tire then the tire tread will wear more in the center. If the air pressure is too low the tread will wear more on the outside edges. Aggressive breaking/acceleration can also be a cause of tire wear problems.
