Thanks for the heads up. Im sure I checked width against RE-11 and Pilot Sport that Im running now, and they all seem very similar. I will do a sanity check again.

Edit: According to Tirerack.com,
RE11's have 10.2" sectional width and 9.4" tread width.
Pilot Sport's have 10.2" , and TBD.
RS3's have 10.2" and 9.5".
AD08R's have 10.1" and 9.9".

Looks like the AD08R's has ~0.1" smaller sectional width than most others, but ~0.5" wider tread width than the RE11's or RS3's.

The tires did get greasy with most drastic change at the end of the 1st session naturally (pressure rose about 6-8PSI). As the day and track got warmer. I had to remove another 2PSI in the rear tires at one point. Eventually, hot pressure hovered at around 33f and 35r at the end of the sessions, and I left it at that.
