One of the problem people forget about new tires be the bike, motorcycle, or auto tires is there is like a hundred mile before they work properly and grip. Friend was killed about 30 minutes after putting new tire on his crock rocket, he rode like a crazy man tring to die all the time. His fatel mistake was doing crazy stuff on a freeway circular road at 95, when the tire started to skid it was all over.
BTW a little rubbing with 600-800 grit sandpaper on a new tire surface breaks that new film, and the tire work better.
