Oem Ecco wheel with 31" Goodyear mtr k. I never adjusted the bump stops but I haven't had any rubbing (street driving and back roads) and wear is the same as the two sets of 30" Goodyear Mtr I've had in the past, 50k miles each set, probably 10k on the mtrk's. I also compared the BFG mud and the firestone Mtr, they seemed "cheap" looking and feeling.
I would mind a 15x8" just to change the stance. *2 cents*
