Are you referring to the Road Smart II? The Q3 is more of a 50/50 track tire vs Roadsmart is a sport touring tire so it depends on what kind of riding you plan on doing. You will wear out the Q3 pretty quick if you do a lot of straight aways or highway riding. Personally i went with the Michelin Pilot Road 4's and haven't looked back.I am lookin at the Dunlop Q'3 or the Dunlop Road Master II's. I am just trying to get some opinions. I had the original Roadmasters on my bike and had no problems. Thanks for your opinions.
