With all the discussions we've been having on the tire/wheel thread, I thought this might be of some use.

By the way, what is the stock offset for a 2013 R/T wheel? Anyone? Also stock is 20" x 8.5" I presume. Enjoy.
(Dealer didn't know, TireRack won't tell me)

 

STock RT wheels is 20 x 8 with 50mm offset according to dodge spec sheet.

 

So the 20 x 9 wheels with 35 offset will come towards the fender edge 1.2598" (right to the edge) of wheel well.
32 offset 1.22"
That calculator works Great!
