Of all the bikes I've owned I've never had new tires on (well other than when I bought this bike). I just had new Metzlers installed on the bike, at on point I almost wished I had paid the extra dough to have them uninstall/reinstall them on the bike(but that's another story about my own stupidity

). I will say that the bike loves to lean into the corners alot easier now, but now it seems the the front end/bike is heavier coming out of turns (uprighting). Is this due to the different profile of the tires (squared off verses rounded)?
