I recently picked up a set from Velgen Wheels. They're the new lightweight series and really well built. 20"x9.5" front and 20"x11" rear. I decided to go with 305's on the 11" wheel since my car is lowered and wanted to be safe on clearance. New tires are Continentials and the contact patch was only 1/4" less than 315's anyway.
Not sure if your '14 has rolled fenders. '15 and newer may have been when Dodge started doing that so you'll want to check on yours. Really helps on clearance.
