It basically a silicon treatment that makes the tires slippery for a little while, this applies to new car tires as well. Last new tire I was a bit keen just up the road from the shop and it broke loose for a bit, it was just like being on a wet road. It wouldn't be much fun if it was raining on the way home after having new tires fitted. Normally the 20mile ride home is enough to clean them up.New tires have a release compound on them to help them out of the mold when manufactured. All the bike shops I have used in the past that it is gone within 100 miles. Ride gently for those 100, gradually increasing lean.
