Wheels of the bicycle may vary in diameter between 70 cm maximum and 55 cm minimum, including the tyre. For the cyclo-cross bicycle the ***width ***of the tyre shall not exceed 35 mm and it may not incorporate any form of spike or stud

aha.
I have a set of 32mm cycloX tyres which dont fit under my full mudguards (very tall). Meaning I need to remove them each time I fancey a blast on the trails. Alway found this a tad weird, as my 35mm commuters fit with a fair amount of clearance.
