I really hate RFT's..I have the bridgestone 18 inch and they really sound and ride awfull. I find they kind of bounce around hard, any little road imperfection is felt. Keep in mind i have 55 series tires, which shouldn't equal to a very harsh ride, but rft's give you hard feeling. So most of the time you get the feeling of boucing aroud instead of rolling . The michelin RFT should be better but i still think RFT's are a bad idea... They're expensive and in case of a flat your not supposed to fix them.
