Is anyone running an 80 with 15 inch wheels? For what tires cost alone for 16 inch wheels, one could get 15 inch wheels and tires of a similar outside width and diameter. I am considering 285/75 R 16s (maybe 305/70 R 16s) or 33 x 11.5 x 15s (maybe 33 x 12.5 x 15s). I plan to buy five wheel/tire combos to avoid VC issues. With a good quality tire and wheel it seems as if 15s and 16s should have the same sidewall strangth. Ride Quality ??? Anyone done this or know of any issues of running 15s versus 16s. Thanks in advance for the help!
