Wheel Alignment
The second part of the law says that the 1.6mm measurement must be across the central 3/4 of the tyre - see above

This means that at any point across the main part of the tyre, the tread depth MUST BE NOT LESS THAN 1.6mm.
Wheel alignment, sometimes referred to as tracking, consists of adjusting the angles of your car's wheels so that they are set to the car maker's specification in order to reduce tyre wear, and to ensure that vehicle travel is straight and true (without "pulling" to one side).
Why is correct wheel alignment important?
- Incorrect alignment can result in rapid, irregular tyre wear, which is bad news for your pocket and can affect the handling and safety of the vehicle.
- Wheel alignment can be affected by driving against a kerb, hitting a pothole in the road or by excessive wear to steering or suspension components.
- If your suspension is misaligned by 4mm (just 2mm per wheel), then for every mile you travel the tyre is being forced sideways by 8.4 metres (28 feet)*. No wonder incorrect alignment results in excessive shoulder wear!

- If your wheel alignment needs adjusting it typically takes about an hour under ideal circumstances.
- Certain vehicles require additional labour and where components are rusted or seized extra time may be required.

- Alignment angles can also be altered beyond the maker's specification to obtain a specific handling characteristic or to fine tune excessive tyre wear. Increasingly many large SUV and performance vehices sacrifice tyre life for driving performance. 
- At Hopley Tyres we have the training and long years of experience needed to recommend the optimum settings for your specific vehicle.
