Wheel alignment and tracking
Wheel alignment and tracking - avoid danger!
Welcome to the Preston Tyre Bay & Autocare - your vehicle and tyre specialist in Preston.
On this page, we would like to tell you a bit more about wheel alignment. We hope you will find this information useful.
If you have any questions or would like to book an appointment, please get in touch.
Wheel alignment and tracking are required after each tyre change (two or all four tyres) and after a wheel suspension repair. This ensures driving safety.
What is the purpose of wheel alignment?
The suspension of a car consists of several components. These ensure that the wheels can move up and down via the suspension travel.
In addition, the steering must always be possible. By driving the car, different forces act on the wheels. Consequently, the wheels must be mounted so that they always roll with the entire tread of the tyres on the road even at a higher load. This is adjusted by toe-in, caster and camber. Everything together is called tracking.
When measuring wheels, the toe in the first step is measured on the front axle. This means that the two front wheels are not exactly parallel to each other, but rather trapezoidal. Hence the term axle geometry. At the front, the distance between the wheels is a few millimetres less than at the side behind the axle. The reason for this is that the wheels drift slightly outwards under load. Then they run parallel again.
The caster means that the stub axles are not at a 90-degree angle. The steering knuckle is tilted back by about two to three degrees. As a result, the wheels are pulled and not pushed.
In wheel alignment, the so-called fall is also an important measure. In a vehicle, the wheels are never exactly vertical. At the top, they tilt outward by a few degrees. While driving, the forces involved make the wheels roll vertically.
How to do a track adjustment
Both the wheel alignment and the tracking can be performed in our Preston Tyre Bay workshop. The axis can be precisely measured with our modern, state of the art electronic devices in just a few minutes. The required data of the axle geometry is available to see on the computer. Our specially trained experts will then adjust the toe-in, the caster and the fall according to the specifications of the vehicle manufacturer.
The consequences of a wrong tracking the driver can feel immediately. Depending on the setting, it leads to understeer or over-steer in curves. Understeer means that the car continues to drive straight despite the steering being turned. When over-steering, the rear of the vehicle "breaks out" when driving through a curve. This is not only unpleasant but also very dangerous.
Even minor changes to the axle geometry are clearly visible on the tyres. As soon as you notice the tread of the tyres is wearing off only on one side, a wheel alignment and track adjustment should be carried out in our workshop.
Proper wheel alignment not only ensures your safety but also saves you good money as your tyres wear evenly and much slower.
