Tires, Wheels, and Brakes - Have wheel alignment checked
Have your car's wheel alignment checked every 30,000 miles (48,000 km), or as recommended in your owner's manual. Also have it checked after buying new tires and when you replace a rack-and-pinion steering unit or other steering parts. Improper tire alignment will shorten the life of your tires as well as cause poor handling. If your steering is stiffer than normal or the vehicle pulls to one side, you probably have an alignment problem.
