GREENVILLE, S.C. (Feb. 5)—Michelin Retread Technologies Inc. and Michelin North America Inc. have named Bridgestone/Firestone Inc. as a co-defendant in their ongoing antitrust suit against retread systems supplier Bandag Inc. Michelin´s amended lawsuit charges Bridgestone/Firestone and Bandag with having entered into an unlawful agreement to delay or block Michelin from competing in the retreading market. Michelin sued Bandag in 1999 in federal district court in Iowa, charging Bandag with violating federal antitrust laws by requiring exclusive franchise agreements that limit the freedom of choice of dealers and end-users in regard to retreading systems and retread products. Michelin alleges that Bandag´s conduct restrains competition in the retread systems market. Bridgestone/Firestone is one of Bandag´s largest outside customers, operating 11 Bandag franchised truck tire retread plants in North America. It also operates 14 retread plants using Oliver Rubber Co. systems, and one plant using its own proprietary Oncor mold cure system.
