What happens when your car is out of alignment?

When your car’s wheels aren’t properly aligned it can cause your tires to wear very quickly or unevenly. You may even notice that your steering wheel may pull to one direction or another. Bad alignment can also cause your steering wheel to shake and vibrate, which over time can make driving very uncomfortable.

Why is my car pulling to the right after an alignment?

One of the most common reasons why your car pulls to the right is uneven air pressure in your tires. A tire with lower pressure on one side of the vehicle has a different height which causes the wheel alignment to shift. Under-inflated tires have an increased resistance to roll, which amplifies steering pull.

What do the alignment numbers mean?

A positive number for example, means that the wheel has too much camber, caster, or toe. A negative number means that there is not enough in the angle of camber, caster, or toe. Both numbers indicate the adjustment needs to be made in the opposite direction.
