Cop Police Wheel best/favorite tire size.

I have 205-60's all around on my Duster on cop wheels. I don't like the looks of the 60 series, I would like to sell them and put 215-65's on.
I don't know about the Dart, but I don't think a set of 235's would fit in the front, too wide and hit the frame rail maybe?
There is another thread on here with completed cars, I posted a pic of my Duster with the 205's on it.
