I decided to go bigger/better on rims and tires. As soon as my rotors show up (!) and I install them, I'll post some photos.

Ended up going with Falken 452's after reading every review of UHP tires I could find. The BMW and Audi forums seem to like them. 235/35X19's and 275/30X20's. All 4 delivered for $720. I REFUSE to pay $300+ for a tire. It doesn't say "Boeing" on the side of this vehicle!

They ride really great and are silent. A little more sidewall flex, but I don't race. A vast improvement over the stock Conti's.

And they fill the holes really great!
