[s-cars] Tire Shelf Life

[mtgadbois at aol.com]

 Way too old for me.  Reference point - 2 years ago (2011) I drove my 993tt on a local track - parade laps.  It nearly slid off the track in a hair pin turn at 30 mph.  My tires are beautiful looking - Michelin Pilot Sport PS2 tires with 1/2 tread or more, no age cracks but they are 2004 vintage.  When I finally drive it more I'll get new tires but until then no track time.  As a side note I had P-Zero Neros on my S6 and I liked them.

Tony asked: 

I'm looking for new summer tires for my (NAC) Jaguar XJ8 and Tire Rack have
Pirellii P Zero for $139 ea though they are from 2007 production. Now I
understand there is a shelve life for tires but would 2007 be a good or bad
buy decision?

TIA
