Time difference depends on how hot you get the tires during the cycles, so it's hard to say accurately.
I *try* to be delicate with the A052s, and keep stints short (~5 laps or so). They don't seem to tolerate being overdriven like some tires. Seem to really reward *careful* driving at 9.5 to 9.9/10ths but quickly start to fall apart at 10.1+/10ths...

Event format is 4 (or 5) sessions on day-1, then 2 (or 3) practice sessions on day-2, followed by 3-lap time-trial a couple/few hours later (plenty of cool-down time)

Tentative plan is to run all of day 1, and practice-1 on day 2 on the 235/45-17s, and do a brief time-trial simulation at 9/10ths for practice-2 on the sticker 245/40-17s to at least get the shift points down with the changed gearing.

Unless the first few laps are magical "golden" laps in the sticker tires, in which case I save them for TT!

I guess it's also a question whether the first heat cycle should be run day before the TT rather than a couple of hours before, or if that matters at all.
