that's pretty much it, I have a set of pirelli P-zero tires manufactured in the 13th week of 2003. Are these too old / hard to run safely? I was hoping to use them for DE days but that's not where I want to wonder about my tires.

thoughts?

This is what the manual says: Note: Under no circumstances should tires older than 6 years be used on your Porsche.

Personally, I would be a bit nervous about mounting 7 year old tires as my DE/track tires.

The rubber has probably hardened some by now, and thus won't offer the grip it once did.

On the other hand, an old-timer recently returned to AX with us 3 weeks ago with 23-year old 008R tires still on his old Colt. He took the win in HS, but said afterward that he thought new tires might be helpful.

Even discounting any potential danger, they probably won't offer satisfactory grip for track work.

I wouldn't run them, due to age.
