On the Mclaren MP1 / P1, the Pirelli P-series tires are replaced every four years - regardless(!) of mileage. Its about a $50,000USD touch each time. Not because of tire costs but that the tires must be balanced, while mounted on the vehicle, on a road course at significant speed by a Mclaren Technician (tire cost + Technician costs + track rental + track insurance, Drive Tech. insurance, etcetera). If its not clear; the root of this procedure is about occupant safety.
The takeaway should be that anyone who elects to drive at high speed - really needs to be mindful of dated tires. Note also that ultra-performance summer tires are dangerous at temperatures approaching freezing - and downright dangerous below freezing (all compounds used in quality hi-performance tries are hygroscopic [absorb water] to produce prodigious amounts of adhesion at higher operating temps).
Driver beware; check those date codes...
Edit: some high performance tire warranties are null and void if exposed to or even just stored at or below freezing (and they can tell - the compound has been altered by frozen / expanded H2O - which has effectively broken the molecular bonds that are essential to hold the outer rubber to the carcass)...
