I'm in the market for new tires. When I bought my RC it came with Michelin Pilot Race tires with a 180/55 in the rear. The shock also has a shim. Is that overkill for me, since I just ride street? It took some getting used to when i first bought the bike, and the front end does shake a little when I hit bumps while leaned over, but I've never had anything scary happen. Where I live in NJ we dont have any twisty roads anyways. I'm contemplating if I should should stay with the 180/55 or go back to a 190/50. As far as tires I'm buying Dunlop D208's or Michelin Pilot Powers, whatever the shop has in stock.
