Attention: TDR Forum Junkies 
I have a '96 2500 with American Racing 16" wheels (correct factory 0. 25" offset as I recall) and 285-75R-16 tires. I have finally found a set of used Rickson 19. 5" wheels with tires I hope will fit. The wheels are off a 2004 Dodge 2500, as are the 245-70R-19. 5 tires.
According to Rickson's website, all dodges up through 1999 (and older chevy's) came with 0. 25" of offset, which is the distance from the true centerline of the wheel to the wheel mounting surface.
From 2000 and up, Dodge factory wheels have 1. 7" of offset, meaning the tire & wheel centerline is moved 1. 45" inboard (deeper into the wheelwell with 1. 70" offset vs. 0. 25" offset). For those trucks, Rickson sells 1. 41" offset wheels, which would move the wheel/tire centerline back out about 0. 30", an insignificant amount.
I am hundreds of miles from the Rickson wheels I am considering buying and cannot measure the offset myself. But assuming they are offset for the 2004 dodge they came off, they would have 1. 41" of offset which is just a smidge over 1" more offset than the factory wheels ( 0. 25" offset) that came on my truck, moving the tire and wheel 1" deeper inboard.
Anyone who has swapped 2000-and-up factory Dodge wheels onto a 1999 or earlier Dodge would have moved their centerline 1. 45" farther inboard, and I'm sure there are guys here who have done that and I don't think they have experienced any rubbing problems, have they? I would be moving mine 1. 16" deeper inboard.
So if 1. 7" offset factory Dodge wheels will work on earlier Dodges like mine, then 1. 4" offset Ricksons should fit even easier, right? Plus, the slightly narrower 245-70R-19. 5 tire and 1. 16" additional offset should help with the current stickout past my fenders that my current 285-75R-16 tires have.
Am I wrong about this reasoning or does anyone have experience with these different offsets and tire/wheel sizes and how they fit?
I would like to move quickly on these wheels & tires but don't want to buy something that won't fit well.
