I used the classic 20's that came on the 2010 RT and put 275/55/20 on the rear and left the front at 245/45/20. It is so sick. It is a blend of then and now. The rear doesn't rub at all anywhere in the well. They were tight to get in but once the weight seated on the rims I was able to tighten the lug nuts all around and WAM. My new look. Stupid looks cool sometimes.
