Will 285 70 17's fit on my 2010 hd 2500? If not whats needed to make it happen? Thanks!

I think NNBS HD's have torsion bars unlike the 1/2 tons. If they didn't fit w/out adjustment, a torsion bar crank and/or torsion key replacement, they will fit. I was able to put 285's on my 2000 Tahoe w/ a TB crank. Check out gmfullsize.com. They've got a good amount of info over there.
