Wheel alignment sometimes referred to as breaking, or tracking is part of standard automobile maintenance that consists of adjusting the angles of wheels to the car manufacturer specifications.The purpose of these adjustments is to reduce tire wear and to ensure that vehicle travel is straight and true without “pulling” to one side.

Alignment angles can also be altered beyond the maker’s specifications to obtain a specific handling characteristic. Motorsport and off-road applications may call for angles to be adjusted well beyond normal, for a variety of reasons.
When car is properly aligned, the wheels point in the right direction. Without proper alignment, the wheels resist your steering commands, as well as each other. It is important to get your wheel alignment checked annually to ensure you get the most out of your tyres./wikipedia
