Tire-maker Michelin says it is recalling about 1.2 million tires sold in the U.S. because an increasing number are experiencing tread loss or rapid air loss. The tires are commonly used for pickup trucks, heavy-duty vans, small RVs and commercial light trucks. The Greenville, S.C-based company says no deaths or injuries have been reported because of the tires. The tires, known as Michelin LTX M/S tires, were manufactured between January 2010 and June 2012.
