I just got some new 225/55-15 Michelin Pilot HX MXM. Nothing wrong with them, and they are pretty decent. 150$ apiece though. However, I think I much prefer the 225/55 over the 205/60 size, that's for sure. Sidewall = bad.

Next time it comes up to replace tires I think I'll end up just getting some 17" rims.
