I've always been a BFG fan and still am. I've ran 35's in both the Toyo MT and Nitto Trail Grapplers on my 2500HD. Pulled both sets off around 40k miles with around 1/4 tread left, which is not bad on a diesel. I'm running 325 60 20 BFG km2's now. I've gotten over 50k miles outa 285's and 305's on 1/2 ton trucks, have seen 70k miles on the old style BFG mudders, man do I miss those.
