I have been extremely happy with my 33 inch BFG MTs, I have played on some difficult trails and not had any real clearance issues. I like 35's as well, but with my 4.88 gears and the fact that I drive it on the highway all the time I didn't want the power loss. Also, without cutting the firewall or moving the front axle forward, my 33's are already rubbing heavily at full flex.
I will put in my 4 cents.
