I need a stock 16.5" wheel or something with fairly narrow width. 8.25" at most. The place I got my truck was good enough to throw in a free 5th HMMWV tire as a spare but it came with no rim. Anybody got one laying around that's in good shape? Also, anybody happen to know what the correct width and backspacing would be of the stock 16.5" wheels on a '86 Chevy K30?
