Race tires harden due to heat cycles.

That, too, for most compounds.    Looking at race tires makes them harder.

Rarely do they last long enough to be effected by O2. 

Usually just between season storage or managing contingency stock, which you have to take when you earn them.   You sometimes wind up with big stacks of tires.   A buddy used to use them for his holiday cards.

No racers I know store their tires deflated.   Hard to do when they are on the car.

Don,

I’ve had the “feeling” many times.   Sometimes I ignored it and paid the price.  I call it putting hope in the flight plan.
