A bad jolt from hitting a curb or pothole can throw your front end out of alignment and damage your tires. Have a tire service professional check the alignment periodically to ensure that your car is properly aligned.
Misalignment of wheels in the front or rear can cause uneven and rapid treadwear and should be corrected by a tire service professional. Front-wheel-drive vehicles, and those with independent rear suspension, require alignment of all four wheels. 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.
Also have your tire balance checked periodically. An unbalanced tire and wheel assembly may result in irregular wear and vehicle vibration.
If you have any questions, please contact your local tire dealer.
