Except in ITR, where anyone can use up to 17", unless your wheels were larger than 17", in which case you can use your stock size too. Oh, but check the spec line, because you can't go smaller than what's listed there.
Or something like that. What a mess! And all of that about wheel diameter? Does anyone think that wheel DIAMETER matters that much?
I personally think that we should allow any size wheel, any diameter and any width too, in all 5 IT classes. Of course, we still have limitations on fender mods, and I'd keep the rule about "tread under the fender" too. So there's an effective limit.
I have three reasons for proposing the change: 1) the existing rules are just one rule layered on another layered on another. It's quite confusing. 2) The wheel sizes are the ONLY difference in prep allowances between the IT classes. The only one. I'd like to get rid of that blight on the ruleset and have all of the IT classes have identical rules. 3) We increasingly hear that it's harder and harder to find wheels for some of the older listings.
