Hey Snowneck, I`m only one man with one opinion............... so here we go!
Too short of a tire on too wide of a rim, it will make the truck look goofy, I added a pick of my 78 Silverado. When I bought the truck it had 15X12s with 33s, looked horriable! Ended up putting on 15X10s with 35X12.50, MUCH cleaner look IMO.
