The stock rubber is on the way out having cleared 30K with sport suspension. I am going back and forth on the RF options vs. standard sidewalls and keeping a can of Fix-A-Flat in the boot. I would love to hear from those with panoramic sunroofs, knowing that the resonance is magnified because of this and the stiffened suspension.

 

Switched to non-RF on my wife's CMS the day that it came home. I've had great experience with Cooper R53S all seasons. The noise level is low, they track well in wet conditions and the tread life is currently at 30K with plenty left.

 

i have the sport suspension but no sumroof

i just replaced my 225/45R18 pirelli p7 summer RFs with 225/50R18 michelin pilot super sports summer non-RFs

the ride is much better, there is more traction and they are very quiet
