Michelin voluntarily recalled around 841,000 BFGoodrich and Uniroyal tires last Thursday because the tread can separate, causing rapid air loss. No deaths or injuries have been reported from the tires, which were made as replacement tires for commercial light trucks and full-sized heavy duty vans from April 2010 until early this year, according to the company. Michelin North America Inc., based in Greenville, S.C., is beginning the recall immediately. Tires will be replaced at no charge. Websites and toll-free numbers have been set up with more information.
