It's not just the tire rating. You need to look at the frame, rim and suspension ratings too. Your weakest link is the maximum rating. In your case, the rims are rated lower than the tires resulting in the lower RAWR (can be verified on the Ford body build website specifications). The frame is the same as the DRW, the bare axle has a 9750 lb rating and the springs are matched to the published RAWR.
