If you still do quite a bit of on-road driving in your truck, I would make sure and get the radial Ground Hawg and not he Bias Ply version. Bias Ply tires traditionally run considerably rougher.

Upon closer inspection, they do not make the radial Ground Hawg in a 35" and do not make it for anything larger than a 16.5" rim.

In fact, the only two Ground Hawg sizes they make for anything larger than a 16.5" rim is 38.5x15 and 40x17. Both of those are bias ply.
