1980 911SC Weissach - Tires (March 2014)

[heimtun]

I am looking at purchasing a Weissach and am trying to identify my tire options. I have searched this and other forums and have read about many tire suggestions.
One problem is many of the tires that have been suggested are no longer available.

I am going on the assumption that the car will have 7" and 8" by 15" wheels - front and rear respectively.

I searched TireRack for a 911SC (they don't a Weissach search option) and they suggested Pirelli P6000 - however, the largest size in P6000 is a 215 tire that supports a 6" to 7.5" wheel. I called Pirelli and they "cannot recommend" using the tire on an 8" wheel.

When I search TireRack for a larger rear tire 225/60 R15 (a tire that will "fit" an 8" wheel) I am presented with a few choices - the "best" choice seems to be a Kumho Ecsta LX Platinum - a tire and tire company I know nothing about.

So, that is the long story... the short question is... What are other folks doing for tires these days (March 2014)?

Thanks in advance for any guidance and/or experience you can provide.
