This shows a 245/45/18 wheel with the suspension sitting on the bumpstops. This is not feasible with the factory suspension without keeping the fender well above the tire. It might be close with a narrower wheel. This one is 8.5 or 9".
Lots more pics exploring the limits in my build thread starting with post #30.

The earlier info by autoxcuda was basically verified on my Dart, except that no fender mod would be necessary.
