I'm going to reply to my own question, because I now have the answer. AWD factory rims have a 6" offset measured from the rear. Non AWD rims have a 5.5" offset. Note the 5.5" rim I used as a comparison was aftermarket, but came off a 2006 charger & reportably had factory offset. I'll send pictures this spring when I take off my winter tires, & put on the wheels with the 5.5" offset. I can say that when I did my comparison that that .5" difference looked much better. The fender still covers the tire, but just barely.I'm told that AWD & rear drive Magnums wheels have a different offset spacing.
Is this true. Thanks
