In your idea would each class would still have a width limit?

I do think that there is no reason to limit wheel diameter and actually think it might make it harder to class cars equally.

It would be much simplier if you could just say max wheel is

ITC - 6"
ITB - 6"
ITA - 7"
ITS - 7"
ITR - 8.5"

Instead of the very long confusing paragraph it is now.
