You know, bfg also makes a 33x10.5r15 (edit as of 16FEB21, Discount tire shows the at and mt BFGs in that size but also the General Grabber X3 and Toyo Open Country M/T) . Been running them for decades now. Third set I suppose. Diameter and offset are not the only factors in rubbing, even with factory suspension. They also make a 33x9.5, but I didn't need to go that thin.
Truck doesn't get driven much, so far at 7-8 years the tires are junk (leak through cracks) but to be fair I also run them at 20psi or less, for a couple weeks, and they pretty much live with CO2 in them, which may not help. (BFG told me not to. I know better than them. Lol)
In any case, aired down they do very well at improving ride, and I've had no complaints thus far on my KO2s, second year running them.
