You are asking the wrong regarding the tires. I picked up my Focus with 90 miles on it from SVT and promptly drove it to Watkins Glen (2 days) Gingerman(1 day), Autobahn (1 day), Road America (1 day) and Putnam Park (2 days).
The edges were a little chewed but nothing that has affected them now at 21k miles.
The schedule will be:
1. Driver's Meeting
2. Orientation Laps. We call them station wagon rides.
3. Group 4 and Instructors on track. Groups 1 & 2 in class.
4. Group 3 on track. 1 & 2 still in class.
5. Group 2 on track.
6. Group 1 on track.
Rinse and Repeat lines 3 through 6.
