I'm not sure who runs USAC. Is it Hoosier or USAC?? When I wanted to run a co-sanction race with the regional midget series they would not run with us even though we allowed American Racer and Hoosier in our Wolverine Series. DK promotions said he would get the race canceled if just one of us ran even one AR tire. I called USAC and they were not sure but called back later to say , yes they could get our race canceled. Hoosier could have our race canceled even though we accept both tires. Who really runs the show? Hoosier, and they are helping to ruin midget and sprint car racing in my opinion. The enormous cost for tires in comparison to start money will continue to kill our sport. Decisions are made on tire brand over what is best for midget racing overall. Remember, Hoosier does what is best for Hoosier not what is best for any series. They want to keep that 100% monopoly even if the numbers go down. I don't have an answer but if tire cost is not gotten under control, racing for the average guy is doomed
