Tire Problems to Look for While Driving

Unusual vibration or thumping noise: Vibration or thumping noises can indicate an out-of-balance tire, one with tread that has a flat spot due to locking the wheels in a panic stop, or a tire with a separated belt.
A pull to one side: While driving at a steady speed, pulling to one side may indicate an underinflated or damaged tire on the side of the car to which the vehicle pulls. If this is not the case, a brake problem or poor wheel alignment may be causing the pull.
