Are you running a staggered setup or a 18 or 19 inch wheel option?

Michelins are one if not only tire manufacturer that even offer any warranty for tire wear on staggered fitments.

Some Michelins has tire chunking issues in certain batches but the best way to find out what your options are is to take it to the retail shop that you purchase them from and ask them to look.

I ran a Michelin Tour HP on my older E53 X5 20" staggered setup with a 32/35psi inflation setup. They worse correctly but just wore out faster. 14K miles and rears needs new tires. The fronts are like new with 8/32nd's left. They offered me a $66.00 credit per tire for the rears. Not that much but better than nothing.

The tire pressure seems to be in line with mine. I live in ATL, GA.

Could be a manufacturers defect and the best way to tell is to take it to your tire place that you got them from or a Michelin authorized retailer.
