Don't forget to scuff the tires before you ride on them, and still go slow and be extra careful until they're good and broken in!! I made this mistake once already, when I put my rear on, first time I rode it made a right turn from a stop and going super slow (barely moving, knowing new tires are slick) and it was like I hit a patch of ice... rear end just slid right out from under me and spun 180 degrees and highsided to the left (low speed, but still threw me pretty good). Being that the bike didn't have a single scratch or imperfection on it beforehand... yea, I was quite pissed. Now the new front tire I just put on I made sure got a good scotch brite pad scrubbing, sandpaper scuffage, several good washings, etc to make sure all that glaze crap was off. I guess I'm a little paranoid now
