I think Car and Driver found the same wear rate on their long-term M3. Those Michelins are pretty soft anmd grippy. It's likely worth investigating other options if tire wear is a concern. Ultimately you will give up some grip and performance, but everything requres trade-offs.
I'd happily trade my E36 M3 for the E92 M3 if so desired. I am getting reasonable tire wear, and the size is smaller and cheaper
