Hello,

I am hoping that you can help me diagnose a tire wear problem. I have a 2000 Mercedes E430, tire size 235/45/17, experiencing abnormal inner tire wear. Attached is a picture that shows all. These are Yokohama's with a 520 wear rating with only 28k miles and are well past their useful life. I've replaced shocks & springs and have had multiple alignments. All four tires show the same wear. I rotate front to rear every 7k miles. Tire pressure is maintained closely. Suspension components have been checked. There is a little play in the steering rack but not excessive. I really don't want to smoke another set of tires so I need to get this corrected asap.

Much appreciated, Matt
