Tyre defects account for a significant proportion of MOT failures across the UK. The good news is that most tyre-related MOT failure points are easy to identify before your test date, giving you time to arrange replacements.
A failed MOT due to tyres that were borderline is an entirely avoidable expense. This checklist takes five minutes to complete and could save you from a retest fee.
Tread Depth: The Primary MOT Tyre Check
The MOT inspector will check that all four tyres have at least 1.6mm of tread depth across the central three-quarters of the tyre width, around the entire circumference. Any tyre below this limit is an automatic failure.
Do not cut it fine. If your tread depth is at or close to 2mm, consider replacing before the test. The investment in new tyres is considerably less stressful than a test failure.
Condition and Damage Checks
MOT inspectors check for cuts, bulges, or lumps in the sidewall, which indicate internal structural damage. They also check for exposed cords — the fabric or steel layers visible when rubber has worn through completely.
Tyres of different sizes or construction types on the same axle will also cause a failure, as will mixing radial and cross-ply tyres. Check all four tyres are the correct size for your vehicle.
