asked the Secretary of State for Transport if it would be possible for MOT application forms, in relation to heavy goods vehicles, to make provision for the inclusion of the serial number of each tyre on the vehicle.

I doubt whether such a provision would benefit road safety, since a certificate of roadworthiness can only relate to the condition of the vehicle at the time it was tested. Tyres, like other items of equipment subject to testing, may legitimately be changed between one annual test and the next. The real safeguard is that it is an offence to use or sell a vehicle with tyres which do not meet the legal requirements.
