Hey, just cause it has been discussed in at least two other threads in the last week doesn't mean that all us guys with 3 inches of lift and tire envy aren't interested. In my Sally Struthers voice, "Do you want more tire? Sure, We all do!"
I know there is someone out there that can tell me how to run 38 on three inches of lift with out cutting my fenders. HA!
Bucky, here is a rundown. Everyone else feel free to correct me if I'm off the mark.
31s will work on the right backspacing. This is what I am running on Ranger "Deer Hoof" wheels. At full flex there is some rubbing, but I have not incurred any fender damage from it.
33X10.50s cutting and/or bumpstopping.
33X12.50s more cutting and/or more bumpstopping.
35s you better get out the saw. Supose to be able to do it with BW fender flares and three inches of lift, but seems suspect to me.
