not sure I like the smaller tire on the bigger plymouth, this is a 235/55/18 from my 2012 Charger, 28" just like the 235/70/15
A big part of it is the wheel.
If your wheel doesn't compliment the car them it'll always look bad.
Think about the factory setup with whitewalls. The whitewall was closer to the bead than the tread. It gave the impression of a larger diameter wheel.
Get the proper wheel and you can bring back some of that look. It'll be okay.
On your C barge I'd look for a 29" tire.
I run a 29.5" tire on the Imp.
