roadie, are you running cvo wheels? that is the only oem in 18 that i am aware of for the rear.
Yes, OEM 2009 CVO blade rims 18" front and 18" rear. My original stock rims were 17" front and 16" rear roulette wheels.
I love the blade rims (especially the way the front rotor set-up is done), but I should have researched the available rubber a little deeper before I purchased the wheel set. I had no idea there was no alternate rear tire available.
