MOT checks for tyres and wheels on motorcycles are divided into just two sections. Please click one of the links below to skip to the section of interest.
Other reasons for your tyres failing the motorcycle MOT test
note: the VOSA manual states that the depth of tread is measured “…throughout a continuous circumferential band measuring at least three quarters of the breadth of the tread.” This excludes tie-bars, tread wear indicators and other features designed to “wear out substantially before the rest of the pattern and other minor features.”
*examples of unsuitable tyres: car tyres, motocross tyres, racing tyres, or any tyre stamped with ‘NHS’ or ‘not for highway use’. You must also fit tyres of the correct load and speed rating for the bike and rear tyres must not be used on the front wheel or vice versa.
Bikes with an engine capacity of 50cc or less only need to have clearly visible tread in a continuous band around the whole circumference of the tyre which covers at least 75% of the width without a break.
There’s an exception listed in the VOSA manual which states that a Metzeler 100/80 – 17 52s ME22 may be fitted to the rear wheel of an Aprilia AF 50 if it is put on the opposite way round to the direction indicators.
Reasons for your wheels failing the motorcycle MOT test
note: the maximum allowable lateral run out or buckling is 4mm for steel rims and just 2mm for alloy. The maximum allowable eccentricity of any wheel is 3mm.
*wheel strength: the decision to fail a wheel due to a reduction in strength is at the motorcycle MOT test technician’s discretion as to whether they feel it is rendered unsafe or not.
