BFG tires WILL be legal to race on Asphalt in 2011. You have to run full sets, you can NOT mix the two brands. USLC is OUT of Federal tires and will not have any for another approx 40 days. The wear bar rule will be waived until tires are available. Hope this helps, this info comes directly from USLC- 03/11/2011.
