Very good point. My goal is to blend my 2001 Dakota (2wd) and the 56 C series into a 56 C-Dakota. So the rear tire sizes will be typical for a Dakota on the stock 16" factory mags, possibly on 17" steel smoothies. Either way basically the widest tire I can mount on a 8" rim width, as I plan to slightly drop the ride height and tuck the tires into the fenders. This will be a daily driver that I'll actually use for some hauling, carrying motorcycles, towing my 5x10 trailer sometimes. So something like a 255/70-16 on the factory mags, or a 255/65-17 on the steelies.
