I throw mine in the mix. I'm running 15 x 8 Blazer Rallyes, 3.5" backspace, for tires, I have a set of 30x9.50x15 C load range Michelins. Plenty of clearance in the front, rear is ok, but i think any larger might get too tight around the outer lip of the fender. My truck has stock ride hight suspension, with the factory 8 leaf HD rear springs.
BTW, if you use aftermarket wheels, you will have to remove the rivits from the front hubs, as the will prevent the wheel from seating properly to the hub.
