I currently have 27x10-14 and 27x12-14 ITP Mud Lites on my Ranger. I am looking to go to the Bighorns (2.0 or original), and am thinking of going back to the 26" stock size to reduce rotational mass. Can anyone speak to the size difference between the brands of tires? I have heard that the Bighorns can run smaller than advertised, but I have also heard it the other way as well. Any help would be appreciated. Thanks in advance.
