Tyres and Wheel Alignment

The main purpose of wheel alignment is to :

• Allow a vehicle wheels to roll properly

• Control vehicle direction

• Support vehicle weight

• Stop the vehicle

Too much positive caster can cause :

• Loose steering

• A squealing noise around turns

• Quick braking action

• Hard steering

The figure shows a :

• Wheel balance machine

• Computerized wheel aligner

• Caster / camber gauge

• Parts washer

If the tyre tread shows a feathered edge on outside, what might be the cause?

• Excessive positive caster

• Excessive negative camber

• Excessive toe-in

• Excessive Steering axis inclination

The figure shows how to adjust the :

• Toe angle

• Caster angle

• Camber angle

• Thrust angle
