I have been running 215-85-16 Futura Scrambler tubeless radials on stock 16X4.5 "clip-type hubcap" rims for over a year without tubes and have had NO PROBLEMO. The ride is pretty darn good, the tires wear like iron and two of them are rated to hold the entire truck with a load! (I know where there is a complete good set of stock rims sitting behind a guy's work shed right now...just eyeballed 'em yesterday!)
