It depends on where you look, don't believe everything you read on forums
It is part of the curse of being a pedant. I don't take anything as true until I have checked myself.
Quote from MOT testers manual:
4.1 Tyres
Tyres fitted to the road wheels only. The vehicle presenter should be informed when it is noticed that there is a defective tyre on a spare wheel.
However, the spare wheel doesn't form part of the test so a defecive one isn't a reason for a fail.
The MOT is a test of the car's roadworthyness as presented. The spare wheel isn't in use so has no bearing on the car's roadworthyness at that time. You could have a boot full of old wheels and tyres but this wouldn't be a reason to fail the car.[/QUOTE]
