Hi Jeremy,
Hope you and family had great Christmas. I've been thinking of different tire combos. I think I got it down to your set up. The Mickey Thompson SC 245/45r20, same stock diameter of 28.7. Rear I'm doing the ET 2 305/35/r20, very close to stock 29.1 at 28.8. Is your car at stock highth? Is there any rub? Inner fender well modification or rolled lips? Last, where did you have your tires mounted? Did they give you a "dont mount a 305 on a 9" wheel?"

This info will really help,
