Mike, you're out there to have fun. The tires will be fine, just drive it!
I got the Falkens on the Miata greasy a couple of times at Oregon Raceway Park and they seamed to recover fine. Those same tires also had prior laps on T-Hill's 5 mile with Hobaugh driving.
It really depends on track temps during the event and how you drive the tires, if you're smooth and don't stress them early in the session they should perform just fine.
Now if you're looking for a reason to justify buying new tires.....by all means don't let me stand in your way.
