33"s will clear fine with your lift. But keep in mind, when you go offroad, and stuff the front tire up into the fender, there still is a possibility of rubbing the mounts. With that in mind, I'm running 285/70/17 (33") Hankook Dynapro MT's without rub under normal use. Still planning on doing the trim in the future to be safe.
Then why do they make tires like the 49" Irok, and 54" Bogger?No Need To Go Bigger Than 33" (285/75)
there is a definite advantage to big tires, especially with ifs, but anythin over 33-35 with the stock drivetrain setup you are asking for repair bills, Personally I would love to run 37's but thats down the line after swapping gears, solid front and 6 inch lift. probably I will wait till warranty is up.Then why do they make tires like the 49" Irok, and 54" Bogger?
It's all what you plan to use the truck for.
I have the OME 3" with the heavy coils. I ended up getting almost 4" from it. The 37's fit for the most part, but rub while wheeling flexed and turned. A 35" tire is a more realistic fitment, and looks more proportioned with that lift. You will most likely have to trim the body mounts, though.
