I usually go off on my "tread width to rim width" rant about now, but with only a 315, I believe you're issue is backspacing. As in too much. Around 05 Ford changed the backspacing on the Super Duty. I think it was due to an axle width change. Anyway, I saw where spacers were needed to run newer wheels on an older Excursion/SD.
Take off a tire, lay it face down, put a straight edge across the RIM, measure down to the bolt mounting holes, if this is more than 4.5", they're too deep. While you could buy spacers, some are cheap and DANGEROUS. I would buy some 17X9s (ideally a 17x10.5, but those are only on Mustangs) with 4.5~4.25 backspace.
As far as a steering limiter, the Dana 60 in my 1/2 mud truck has them, but not the Dana 60 under my Souper Doody.
