What tires to get for 2007 Corvette Z06?

[Kristoffer Gjevre]

I need new tires for my 2007 Corvette Z06 and likely will not get extended mobility/run-on-flat tires again.
So I am curious what tires and sizes people are running for autocross?
I looked at the 2022 Solo Nationals results and see Yokohama and Falken are used in A Street for similar cars, but can someone tell me what model and size those tires are?

Thanks,
Kristoffer

The fast kids run 18x9.5 front and 18x12 rear wheels in A street. 265/315 Yokohama A052 or 285/315 Falken RT660. I believe the guys running “Multi”were on 285/30/18 Falken RT660 front and 315/30/18 Yokohama rear.

If you want to stay on your Factory 18x9.5 front and 19x12 rear wheels, I like the classic 275/35/18 front and 305/30/19 rear combo. Falken RT660, Nankang CRS, and even the new Nexen Nfera Sport R are all pretty fast tires in those sizes. Falken RT660 also comes in a 315/30/19 rear, which fits the 12” rear even better.
