American Racer Tires for Street stock?

Mahoning Valley has partnered up with American racer tires now....they haven't given us much detail as in to which tire compound they are going with for the street stocks but I'm assuming they are going to stick with the compound closest to what we ran with Hoosiers 790's and that would be the AR 970.....anyone with any info on that compound or any compound similar to that, any info would be greatly appreciated. thanks
