Ryan Newman blew a right rear tire in practice today, with teammate/owner Tony Stewart close behind, taking out both Cup cars with significant damage. Newman and Stewart will be going to back up cars and starting at the tail of Sunday's field. Tony in typical Tony fashion, lost his cool with the press when questioned after leaving the infield care center on how the backup cars would affect their chances of winning the 500. Tont went into a rant about Goodyear's tires, similar to his dismay with Goodyear during the 2008 season. Details on Fox Sports . com.
