I can sort of believe monitoring degradation; if Pirelli constantly monitor the tyre temperatures and sort of run their own live simulation; from which they work out deg; but wear? How?
Only thing I could say is very, very accurate slip and speed/rpm sensors, you'd be able to work out both the change in acceleration as the tyre loses rubber and correlate that against speed/wheel slip/engine rpms on the straights for the tyre diameter.
Hell of a set of sensors on board the chassis these days if they can do it that way though!
