1. Wheel alignment;Alignment
terminology
Incorrect alignment can result in rapid irregular tyre wear and can even affect the
handling and safety of the vehicle.
Wheel alignment, or tracking, is the process of ensuring your vehicle’s wheels are
set to the optimum position, as per the car manufacturer’s specifications, so that
tyres wear evenly. Incorrect wheel alignment can be caused by hitting a kerb, driving
into a pothole in the road or by excessive wear to steering or suspension
components. It is important to get your wheel alignment checked annually to ensure
you get the most out of your tyres.

2. Alignment terminology
Wheel alignment involves checking the direction and angle of the wheels. The
misalignment positions are often described as toe in, toe out, positive camber or
negative camber.
"Toe" refers to whether the front of the tyres are closer or further apart than the rear
of the tyres. Different types of vehicles need different toe settings to allow for the way
that wheels pull either towards each other or apart.
"Camber" is the inward or outward tilt of a tyre. The camber is set by the vehicle
manufacturer, and can be affected by potholes in the road and may need to be
adjusted periodically.

3. Camber
Viewed from the front of the vehicle, camber describes the inward or outward tilt
of the tyre. The illustration below shows whether this tilt is referred to as positive or
negative. The camber adjustment maximizes the tyre-to-road contact and takes into
account the changes of force when a vehicle is turning. Camber is the one
adjustment that can be set according to driving habits. Generally, if you drive more
aggressively when cornering, more negative camber can be set. If you drive on
highways and do very little hard cornering, more positive camber can be set.
Toe
Viewed from above the vehicle, toe describes whether the fronts of the tyres are
closer (toe-in) or farther apart (toe-out) than the rears of the tyres. The illustration
below shows this relationship. Toe settings vary between front and rear wheel drive
vehicles. In a front wheel drive vehicle, the front wheels try to pull toward each other
when the vehicle is in motion, which requires a compensating toe-out setting. A rear
wheel drive vehicle works just the opposite, necessitating a toe-in setting. Stated
differently, toe is set to let the tyres roll in parallel (at zero toe) when the vehicle is in
motion.
