AWD mopars have a offset of 32- 42 mm Offset is the distance between the true center of the wheel, and the point where the wheel mounts to the hub. That distance is measured in mm you can visibly see this when looking at wheel they look almost flat across the face of the rim as opposed to RWD rim which seem to fall to the center. I use 20" 8.5 wide with a 38mm offset in summer and my stock 18" 7.5 wide 32mm in winter. AWD mopars have a higher ride height so it's hard to have that filled in look - go with a adjustable air suspension if you want to lower it, cause if you lve in a state that gets snow you'll want that stock ride height in winter the Maggy is awesome in the snow,
recommend that you use nothing larger the a 20" 9 wide rim as it could cause unneeded wear on the suspension. Oh and Bolt pattern is 5x117 (5x4.5) and because I researched thinking I could use those awesome Durango SRT wheels they are 5x127 (5x5)
Not used to this forum setup so hopefully this comes through. This car does have an air suspension already installed. I plan to change it to another version of air suspension if possible as the setup right now has the pumps in the spot where the spair tire is supposed to be kept. I have heard of some air shocks that you air up individually which does sound like a better option to me. I am in SE Texas so snow is almost certainly not an issue. However recent events have shown that flooding is definitely something to look out for.
