Wheel alignment (sometimes referred to as tracking) is a service that involves correcting the angles of your wheels so that they are accurately re-set to the original manufacturer's specification. It's recommended to get this checked whenever you replace your Tyres, as, over time, the rigours of driving on the road can cause your wheels to become misaligned. You may need to have your wheels aligned if your car has recently had a more significant knock or impact, such as going through a deep pothole.
