Dear Tom and Ray,
I have a 2008 ML350 Mercedes SUV. On each set of tires, the OEM tires and a replacement Continental DTS series, I have seen uneven wear on all four tires. Basically, when you run your hand around the tire (not across the width of the tire, but around the circumference) you can feel that the tread is higher on one side of one of the tread cubes then the other. When you run your hand in the other direction, you cannot feel the edges. I have had the tires aligned with the new replacement set of tires and the inflation has been according to the information on the cars sticker. They have also been rotated front to back as they are asymmetrical.
What do you think is causing this wear? I am about to buy new tires.
