What goes wrong?
The most common MOT failure reasons are tyre tread depth not in accordance with the requirements, a suspension joint dust cover missing or no longer prevents the ingress of dirt etc and a spring or spring component fractured or seriously weakened. The top issue, tyre tread depth not in accordance with the requirements, caused 162 failures in 2024. Checking tread depth (1.6mm legal minimum, 3mm recommended) before your test can save an unnecessary fail. You can check prices at Black Circles if you need replacements.
