I'm getting ready to buy new Wheels and tires for my 2001 SCREW. I currently have the stock 17" Chrome Navigator wheels. does anyone know what the offset and back spacing is on this wheel? I'm looking to switch to a 16X8 Wheel and a 285-75-16 BFG AT KO tire. The Wheels I'm looking at are American Racing Renegades. They have a +12 offset (nothing listed for the back spacing). Will these be similar to the 17 wheel that are on it now. The other wheels I'm looking at are the Crager soft 8 397 with a 4" back spacing and the Rock Crawler 97 w/ 4.25 back spacing. both 16"X8". Any ideas?
