Why a change on the tire rule. We have run salem for four years on american tires and that is all we have. We live 30 miles from the track planned on practice friday and race saturday. We have two cars that would have been there. With entry fees and pit passes and with how many people that come with us that is $300.00 min spent just at the track.
