I found that with the sport suspension and 18" Non-RFTs the ride quality actually improved when I ran higher pressures. I realize this is completely counterintuitive but my wife made the same observation and when I posted my impression here (thinking we may have been imagining it) there were others who had expericenced the same thing.
