While I haven't driven it on any of the extra rough roads (SE Michigan's roads are incredibly awful), The normal but still somewhat rough roads I have driven it on make it feel extremely good. It feels smoother with this tire/wheel combo than it did with my previous 225-60-15 tires. The even more amazing thing is that the car feels like it tracks better now.
I have the alignment at -1.5 camber +3 caster and 1/16 toe-in per side. We'll see if I decide it's worth it to take the UCAs off to add more caster or not. It's a garage alignment so it's only my time for that. I have some real turn plates coming now so that will help.
