Three of the original Michelin energy mxv4 tires on my 2007 Mazda 6 have failed to maintain proper air pressure. Two of the tires had defective valve stems and the third tire lost air pressure while I was driving on the freeway and needed to be replaced altogether. These three tire incidents all occurred between 5/29/09 and 7/23/09.
