Speaking of Tire Rack, why don't you guys all log in a request for PSS in a 285/30/19 fitment. That is the exact fitment on the M3 GTS in Europe (which of course rides on the same wheels as our cars), and it has 255/35/19 up front.
I've talked to TR a few times, they said if enough people show interest they will forward it on to Michelin. Per TR, the 285/30/19 tire is quite popular with the Corvette guys already, and I reckon between us 1Mers and M3ers, we can hopefully put this on Michelin's radarQ
