Hey Mizz,
I think I am going to run 35X12.50 on them...and probably either the toyo mt's or the Nitto Mud Grappler.
I was going to go with some 37's, but I just do not want to deal with tons of rubbing. The 35's will allow me to still flex the way I can with the stock set-up.
Did you get your set from the ebay guy? tomzwheels?
