Thanks guys!
I think I knew the answer deep down, but I had to ask again anyway. The 35 on 18 would probably be best for me because I tow my trailer all over the West, and because I never know when I'll take off to "see where the road goes."
However, I now know if I choose the 37 on 20's I won't be giving up any sidewall depth.

He doesn't need new tires and wheels for that...

I remember you had 18's, but wasn't sure how you liked them in the Moab environment.

Sometimes I get lucky

and find a road like Kane Creek that I have to pound on to get through.
