I'm going to be very blunt with you. You will not.
You are about 5-8 events too early to worry about what tires to use, in my not so humble opinion.
AMEN!!! Just be humble and learn. Best way to be on your first 7-8 outings.
The only reason I can see for being this concerned about which tires to use is so you don't ruin your daily driving tires. And that would only matter if you knew you were going to be going to more track days after this one. We could also talk about the frequency of those track days.
