KUALA LUMPUR, Malaysia (July 11)—Aircraft maker Boeing Co. has signed a two-year agreement with Malaysia´s Simex Aircraft Tyre Co. to consult Simex on its efforts to get its radial aircraft tires certified for use on the Boeing B-777 twin-engine wide-bodied airliner. Simex, part of the Sime Darby Bhd. Conglomerate, is one of only five companies to make tires for commercial airliners. It has produced bias-ply aircraft tires since 1975, but is gearing up for radial production by 2002, according to Managing Director Mohamed Ishak. "The success of manufacturing of the Boeing 777 aircraft tires will make Simex the third company in the world to manufacture and supply the radial aircraft tires for wide-bodied aircraft," Simex Chairman Ahmad Zubir Murshid said in a prepared statement. The agreement does not guarantee any orders for Simex, but will put the Malaysian company in a position to bid for business. The B-777 uses 14 tires, each costing between $2,000 and $2,500 and typically lasting 300-400 landings.
