Two inches is too much of a difference. I am sure you could sell your stock wheels and tires and cover the cost of the fifth tire and wheel.
As far as wheel width I would say go with 8 Inch, so get you some 15X8 steel wheels with 3.75 backspacing. I am guessing you will be going with 32X11.50 or even 32X12.50 either way and 8 inch wheel will be plenty big.
This is just my .02 worth.

That way I figured I could just buy 4 tires and 4 rims. Is there a market anywhere for 4 30" tires on Canyon rims? Also, what width rim do I need with the steelies? Thanks again, Scooby
