Gary,
At the Topeka DBL REG race (I think it was in June or July) the Hoosier guy gave me a sheet that said if you bought your tires from the suppliers on the list in Mid Div that you could get some sort of free tire/ tires. By then I had enough I had bought in Ft. Worth to make the season so I didn't use it. Was planning on trying to do it this year, but have not seen anything about it.
