I just changed from 225/45x17 to 225/50x17 (Michelin Pilot Sport 4) to achieve more comfort through better cushioning. My Elegance 125Tdi wagon feels much better in ride and general insulation from the road. The vehicle also looks a lot better in my opinion. The wheels rotate 17 times fewer per kilometre than before according to a specialised online calculator(tyresizecalculator.com/charts/tire-size-chart-metric-by-rim-wheel-diameter). Not sure what that means in economy or performance; A member of the Briskoda website says that that change makes the speedo about spot on, instead of 5kph fast.
