Several other sites sell the smooth street tires as well at the site you quoted. http://www.tiresunlimited.com/ALL%20TIRES/Bridgestone/Bridgestone%20MC/bridgestone_trail_wing.htm But I can´t get anyone at these sites or Bridgestone to confirm that they are suitable for the TW200 on pavement. I imagine that the street tires might be better over tram tracks in a big city (Toronto) as well.
