TOKYO (Oct. 3, 2003) — Bridgestone Corp. has begun supplying run-flat tires to BMW A.G. for installation on its new 5 Series model car family, the Tokyo-based tire maker said.
The Potenza RE050 RFT tires—offered in sizes 225/50R17 94W, 245/45R17 95W and 245/40R18 93 W—are for sale in Europe, the Americas and Japan. The 5 Series vehicles are high-performance sport sedans with 2.5-, 3- and 4.4-liter engines.
Bridgestone's run-flat tires for BMW will have reinforced sidewalls to maintain tire shape. The tires also can be installed on conventional wheels, Bridgestone said. The 5 Series is the fourth BMW model family to be equipped with Bridgestone's run-flats, which the tire maker began producing for auto makers in 1999.
