I have searched and found nothing on this size of Toyo Open Country AT. According to Toyo's website, this tire measures (34.3"x12.5"). I'm am thinking of mounting it to a 9" wheel, 5.25" backspacing, with a 2 1/2" leveling kit on a 04 screw 4x4. Has anyone seen any pictures, or running this set up? My choice is between this set up vs. 305/55/20's, (33.2"x12.0"). Thanks in advance.

 

If they fit it will be close. At the least you will probably have to do some trimming.
