7k miles and tires are Shot!

[ABMW]

2011 35D loaded with almost 7k miles on the car, 214, 20"wheels with run-flats, completely stock. The car just turned one year old and has been driven like Ms. Daisy was in back.

4k of the miles are freeway and 2500+/-k are local highway, quite literally there might be 200 of city miles, but that's it. Both front tires area at their wear limiters. I, just, had a flat in the front drivers side, which was covered by the BMW wheel/tire warranty I purchased. The language is fuzzy on the contract and says there must be 2/32" of usable tread. So, I suppose they consider tread beyond the wear limiters to be usable tread.

I expected to get around 12k to 15k miles at least, not 7k. To me, that seems ridiculous. There's no abnormal wear on the tires whatsoever, I check pressures weekly, no spirited driving, towing, or other type of behavior that would cause the tires to wear so quickly.

Not a happy guy with a $1,700 tire bill next month (including tax). The alignment is fine and spot on. Any thoughts? These are the runflats, and the vehicle is completely stock. Havent's called BMW yet, but with 7k miles on it, I'm thinking about doing so. That seems a bit absurd...If I was "railing" on the SAV, sure. But, cruising at 80 on brand new highways 1-10 & I-5, makes me wonder why the hell these tires are completely shot.

Argh.. Also rear camera also went out (there's a new shielded cable for 2011/2012 models that prevents electrical interference from the exhaust system, apparently, sounds odd but the cable is on order, FYI), the lane departure system suffered a failure while driving on the freeway, complete with polite warning text informing me of such a malfunction (working on this), and the "alarm arm/disarm chirp/horn is only working 50% of the time.

Any help would be greatly appreciated. If everyone is getting 7k miles, okay, I'll take it. But, I clearly recall reading people achieving far higher mileage (about double).

Am I wrong?
