Which Ultra HP All Seasons for CL55?

Which UHPA/S tires in stock size (?) 275/40/18 (rear for 18x9 wheel) does TR recommend for the 2005 AMG CL55?
Summer tires are NG here in NH even in the summer. The stock Bridgestone 050s rears wore out after 5k miles even after alignments, etc. Also, they are hard as hockey pucks if the weather drop below 55 degrees F even if properly warmed up after 10 miles of conservative driving. Take a drive in the White Mountains in July and you'll see what I mean!
I am willing to wait until spring if there are some new designs on the market...since I have my ice tire on there now.
Thanks for your advice.
