Definately the tires on the blue track model are Michelin Pilot Sport. I went to http://www.tirerack.com and was able to match up the tread design.

Tirerack's information on the tire is here: http://www.tirerack.com/tires/michel...ilot_sport.jsp

UTQG is 220 AA A. Also it looks like the 225_45_18 and 245_45_18 are both Y-rated tires. Y=186 MPH, 300km/h, Exotic Sport Cars

 

Yes, but according to ZISME, the "final" production car will use Bridgestone.. Just FYI.
