Guideline on Buying Tires Wheel Balancing and the Performance of Your Car | Page 5

Wheels will generally become misaligned over time due to adverse road and driving conditions
including hitting potholes, curbs or speed bumps. Wheel alignment is done by adjusting the tie
rods and control arms so as to ensure correct alignment. Your car wheels should be aligned to
their optimum positions according to the manufacturer’s recommendations by adjusting the
toe, camber and sometimes the caster angles.
Toe is term used to describe whether the front of the tires are closer or further apart than the
rear part of the tires; ‘camber’ describes the inward or outward tilt of the tires while ‘caster’
refers to the angle between the steering pivot axis and the vertical that is usually adjusted by
moving the suspension struts.
