Wheel alignment and Balancing is the entirely different term, but many of them getting confusing this thing. Wheel alignment is the process of adjusting the angles to make perpendicular to the ground and ensure parallel to each other. The main objective of the alignment is to get the maximum span of tyres. It helps the vehicle that to maintain their track straightly while driving on road.
This wheel alignment is categorized as camber, caster, and toe based on Primary angles and then further classified as;
Front: Caster (left & right)
Front: Camber (left & right)
Front: Toe (left, right & total)
Rear: Camber (left & right)
Rear: Toe (left, right & total)
Excess of toe-in or toe-out may cause the tires to scrub. Too much toe-in causes to accelerate the wear at the outboard edges of the tires, while too much toe-out may cause wear at the inboard edges.
Wheel Balancing is to allow the tires and wheels to spin without causing any vibrations. Wheel Balancing ensures that all of the tires are balanced with the wheel weights for smooth running of each tire. There is a possibility that the steering wheel will rock when your wheels are not properly balanced at particular speed.
Static balancing machine is used to measure static balance, where the tire is placed in its vertical axis on a non-rotating spindle tool. The amount of deflection shows in static balancing machines which indicate the magnitude of the unbalance. The angle of the deflection indicates the angular location of the unbalance
Dynamic balance describes the forces tested when the tire is rotated, usually at a high speed. The assembly is accelerated up to a speed of between 100 RPM to 300 RPM.
