CHECK THE INSIDE EDGE OF OF YOUR REAR TIRES!!!!!!!!
Sorry for yelling, but if other people are experiencing what my 18" Hankooks experienced, it is definitely a safety issue. My car is almost a year old and near 28,000 miles. I had snow tires on for about 3 months this winter, so I would estimate 20-25k on the OEM tires, but still plenty of tread as I put on a lot of highway miles. I was experiencing a vibration that didn't go away after 5 minutes or so. It was fine at low speeds, but on the highway, it became noticeable around 70 mph and got progressively worse with increased speed. I figured I would rotate my tires to see if it would help and check to make sure no
wheel weights had fallen off. When I pulled my right rear tire, this is what I found on the inside edge.

The inside edge was worn down to the belts from the inside edge to about 1" from the edge. The step of missing rubber was in excess of 1/8". It wasn't the whole circumference, but about a foot along one section of the circumference. I had not received my letter yet, but my dealer looked up my
VIN and said I was eligible. They got the tires in in a couple days and just got them put on today. There was never any discussion of changing the ECU, but I noticed the tires were V-rated (149 mph I believe). They wanted me to pay for an alignment, but my winter tires showed no signs of uneven wear so I had them perform a complimentary alignment check. Everything was within spec, but I noticed the spec on the rear camber is -0.9 to -1.9. Mine were at -1.8 Anyone with experience with modified suspension setups care to comment whether that much rear camber could cause edge wear this severe? I'm leaning toward defective tires. The dealer was adamant it was NOT a recall but a "customer satisfaction campaign".
Anyways, the vibration is gone. The Michelin tires sound a little noisier on the highway than the stock tires were when new, but it's still a quiet ride. The wind noise off the driver side-view mirror is still louder than the tires.
