Try the Colorado Jeep Club. You might have more luck.
Colorado Jeep Club
I believe we have to have coverage of the fenders here in CO, but I have 33X15.50's on 4" BS without fender flares at all and have never been called on it. I do get a lot of mud and road sludge on the sides and windows though.
The one thing I know is that you ahve to have either a rear view mirror that is adjusted to see from 100 feet behind you to the horizon OR 2 side mirrirs. So going without doors/mirrors all summer is fine as long as you have a rear view mirror.
