YES I bought used CF wheels that had tires on them with a CT rear so I decided to try the tire combination and it sucked I tested them for almost a month to see how the combo worked and was not anything that I would want on my bike really screwed up the way the bike handled so I replaced them with an excedra max front and a Mich commander 2 rear and WOW what a difference this combo transformed the bike into a sweet handling beast a great combo that I reccomend for these wheels
