Wallace, I'm already running the noted size in the BFG AT, but they were pretty close to the UBJ when they were new, and the Duratrac seems wider at the corner of the tread than the BFG AT does. The BFG AT is 30.6" with 8.0" tread width in that size, and the Duratrac is also a 30.6" with 8.1" tread width in LT/E (and 7.6" tread width in SL, but I'd get the LT/E).
From my build thread:
James, you're probably right... It'll probably be fine, but before I special ordered $900 in tires, I figured I'd check... In fact, I've already designed and had a couple sets punched a couple years ago, of 1/4" aluminum spacers in our tread pattern... I don't remember who I sold them to, but I do know I did them.
