In a nut shell wheel alignment is the position and angle of each wheel in relation to each other. Not to be confused with wheel balancing which is something totally different. Besides both affecting ride, handling and tyre wear wheel alignment and wheel balancing are completely different things. The above diagram basically explains the process. Toe relates to wheels pointing inward or outward. Camber refers to the angle of the wheel perpendicular to the road. Castor relates to the position of the front wheels forward or backward and is a measurement between the steering axis and the vertical axis. Keeping castor to specification assists with keeping your vehicle traveling straight and self centering of your steering wheel. Having all three aspects of your alignment adjusted to specification will give your vehicle the best possible handling dynamics along with maintain optimum tyre wear.
Alignment of wheel means that all the wheels of the car are properly aligned in the way they should be. With time and usage of a car, these settings usually need adjustment to keep them properly aligned. Proper wheel alignment for a car plays a significant role in the dynamics of the vehicle in motion. Technically, it is an act of making sure that the geometric angles of Caster, Camber and Toe are correct in a tyre, if you don’t know these angles, you need not worry, just make sure that you get the alignment done on a regular basis, well how frequently, read on for more details.
