A wheel alignment is done to make sure the vehicle's wheels are running parallel to each other, and that the tires meet the road at a correct angle, to fix or avoid problems such as irregular tire wear, poor handling (pulling to one side) or a crooked steering wheel.
Every wheel has camber, caster and toe angles - when they are correctly aligned, your car drives straight. When the camber, caster and toe angles are misaligned, wheel alignment problems can arise. Your vehicle can pull to the left or right or your tires can wear unevenly.
