Obviously the differentially sized tires rule out rotation which would give
you more life, but 30K miles out of sport tires isn't too bad. I got 20K out
of a set of Michellin Pilot Sports on the back of my Boxster.
FWIW, I've had good experiences with tires from The Tire
Rack -http://www.tirerack.com/content/tirerack/desktop/en/homepage.html -
cost wise especially if your tire vendors aren't super competitive.
I became a proponent of Michellin tires in the late 60's when I put some
Michellin X's on my 59 Austin Healey Sprite, the improvement in handling
over the removed bias tires was astounding. Been a believe in them ever
since. IMO opinion they're the best for performance and durability.
Was bummed out when I discovered Michillin doesn't yet make a tire for my
GTS.

The rears are actually worn smooth, well below the minimum tread depth.
They become somewhat unsafe as a matter of road hazards ... Punctures and
such when they're so thin. Never mind the odd fix-it ticket for driving on
worn-out tires if a peace officer wants to brighten your day. I just
haven't been watching as carefully as I usually do. Too many other things
taking up my attention.
As to the price, well, these are differentially sized, low profile, high
speed sporty car tires (for '00 Mercedes SLK230 K). They run a little over
$100 per tire, add shipping, mount and balance, old tire disposal fee,
surtax, sales tax, and four wheel alignment inspection .... The cost will
total between $690 and $760 by the time the job is done.
The tires that have just worn out were Continental ExtremeContact DW
205/55ZR16 91W-225/50ZR16 92W "Max Performance-Summer" tires. They are
rated for 25000 mile lifespan on this weight car; I eked 30,000 out of
them. Sticky and lovely on warm and wet roads, pretty dicey on frozen
tarmac though.
Unfortunately, I hunted around and the rears are out of stock everywhere
at present. So I'm giving the Goodyear Sport All-Season V-rated (same
sizes) a shot this round. Tread pattern looks similar, they're rated for a
bit more mileage (30-35K miles), and feedback on them from other SLK230
owners seems positive. Ride quality is rated in the same ballpark, noise a
bit quieter, etc. On the numbers and specs, they're a toss-up. They're
about $20 more than the Contis, which if I can get another 5-10K out of
them is another toss up.
Fun fun fun ... ;-)

Godfrey, tire tread depth at the wear bar doesn't necessarily mean they
need to be replaced. If the wear is even across the tread and you you're
not anticipating significant rain they can still be safely driven on
awhile longer. If these were mine, here in Michigan I'd probably drive
them thru the summer but replace them as winter approaches.
A trade off of low tread depth is better adhesion, all other things
equal. However tire noise is worse
The tires? Ach, I was expecting to do them this year anyway, just taken
a little by surprise by the rapidity of their decline.
