Goodyear will seek tire-testing changes: NASCAR limits tires for Nextel Cup testing, barring teams from using Goodyear's except at the seven major authorized tests. So, teams have made side deals with Hoosier and Michelin subsidiary B. F. Goodrich for test tires. Stu Grant, Goodyear's racing boss, said he plans to talk with NASCAR about changing the tire-testing rules "to try to find a solution to this thing, because what we've got now is not a good situation. "The whole testing thing has to be addressed, because the teams are not happy. They're asking me for tires, and I cannot supply tires."(Winston Salem Journal)
