How Wheel Alignments Work
Wheel alignment involves adjusting the angles of the wheels to ensure they are set correctly according to manufacturer specifications. Despite the name, the process actually involves adjusting the vehicle’s suspension, rather than the tyres or wheels themselves.
There are several key components to a proper wheel alignment:
- Caster refers to the angle of the steering axis, affecting high-speed stability and steering response.
- Camber is the inward or outward tilt of the tyres, which influences tyre-to-road contact and cornering stability.
- Toe describes the angle at which the tyres point inwards or outwards in relation to each other, affecting tread wear and vehicle tracking.
- Ride height is the distance between the vehicle’s frame and the road, serving as the reference point for all alignment adjustments.
How Misalignment Affects Tyres
When alignment settings are off, tyres wear unevenly, leading to premature replacements and reduced performance. Incorrect camber settings cause excessive wear on the inside or outside edges, while incorrect toe settings lead to feathered tread wear and reduced stability. If the caster settings are out, the vehicle may pull to one side, requiring constant steering adjustments.
Hitting potholes, curbs, or driving on rough roads can gradually knock wheels out of alignment, making routine checks important. Suspension components can also wear over time, contributing to alignment issues that affect tyre performance.
When to Get a Wheel Alignment
Wheel alignment should be checked every 10,000 kilometres, every six months, or whenever new tyres are fitted. Signs that a vehicle may need an alignment include:
- Uneven or rapid tyre wear
- The steering wheel pulling to one side
- A vibrating or off-centre steering wheel
- Reduced handling and stability
