Hoosier Tire pays big money to USAC for allowing only Hoosier tires the only tires allowed and you the racer are paying this every time you buy a Hoosier tire. So Hoosier makes tires that don't last so the racer has to buy more. I remember back in the day when I ran American Racer tires, these tires were better bald than Hoosier tire were when new. Some say Hoosier tires are not rubber but a plastic compound, this I don't know but there are better tires than Hoosier.
