Common examples as to why you may notice abnormal wear are that your alignment, or problems with your steering, are affecting the wear of your tyres. In some cases, the suspension in your vehicle can result in rapid, irregular tyre wear, which can lead to expensive problems.

If your suspension is misaligned by even the smallest margin, for every mile you travel the tyre is being forced sideways, which causes the excessive shoulder wear of your tyres. Ensuring that your wheels are correctly aligned can add thousands of miles to the life of your tyres and also increase fuel efficiency by reducing rolling resistance.
