One problem related to tire bead has been reported for the 2008 Infiniti G35. The most recently reported issues are listed below.
My wife was traveling north on 476 from I-95 south before exit 3 without warning the right rear tire blew out which cause her to loose control and the car swerved and made minor contact with a curb or something. The tire came completely apart except for the inner and outer set bead which stayed on the rim.
