Having new tyres fitted and setting off on them for the first time can be a bit daunting especially if the tyres are of a type you haven't tried before.  Listening to all of the stories from friends about "scrubbing in times", watching racers slide off on their outlap and the commentators wax lyrical about new tyres and their "break in period", it's enough to put some people off.

However once you've owned a bike for a few years and had a few sets of tyres it becomes second nature.
