This is getting a tad annoying. Dealer can't seem to figure it out, maybe someone here has an idea?

Real quick, this does not look like normal feathering as I've seen it described, but excatly like the second diagram in this link:

I got brand new Michelin's and a dealer alignment. Car drives great, straight, good steering, etc. After 2000 miles I noticed my left front tire is feathering on the outside edge tread blocks. I had the dealer throw it back up on the rack. They say all is still within spec and same as 2000 miles ago. I asked to check all the components and they said all is tight. The direct quote from the dealer was "I wish I could tell you it was this part and X amount of dollars and it would be fixed, but I can't." I guess I have to appreciate his honesty of not just telling me to rebuild the entire front end or something, but still, I'd like my Michelin's to go a few 10,000 miles (or 80K like they say) instead of maybe one or two seasons.

This has been the fourth time my car has seen the rack for an alignment (twice at a stupid chain that really screwed up) and my second set of tires. Obviously, something is wrong here.

The only advice I left with was to fill up the tires more than normal to try and keep the wear off the outside.

In case it matters, this was Mercedes Benz of Westminster here in Colorado. I've heard nothing bad about them and was recommended to go there by a highly praised Benz shop in Denver since they don't have alignment equipment.

EDIT: Just posted this as a reply but thought putting it here would make sense incase anyone else has this issue they won't have to read to the end.

I think I fixed it. I did my wheel bearings awhile ago and figured it might be just a hair loose, since I know you don't really want to tighten them too much, and they are supposed to have a tad bit of play. Well, I tightened it up 1/8 to 1/4 a turn. Drove 900 miles and I haven't notice any new wear and the hub didn't feel hot when I pulled over. I think I'm calling it fixed.
