One problem related to tire bead has been reported for the 1999 Chrysler 300M. The most recently reported issues are listed below.
Contact stated wheel rim peeled and caused the air to come out of tires. Two out of four tires were flat in the morning. They rotated them, and eventually all four tires became flat. She talked to the Chrysler dealership, and they told her that the beads in the tire rusted and popped loose. This caused the tires to lose air. The manufacturer said there was nothing they could do about it. Noticed this problem one year ago.
