Winter Cycling - Tubeless Studded Tire Option

Bikeforums.net is a forum about nothing but bikes. Our community can help you find information about hard-to-find and localized information like bicycle tours, specialties like where in your area to have your recumbent bike serviced, or what are the best bicycle tires and seats for the activities you use your bike for.
Having recently upgraded to a Trek Liquid 25, I'm in need of some new studded tires, but they have to be tubeless. Does such an animal exist? I've searched a little bit, but haven't found anything too specific.
I'm sure the standard-equipment knobbies on the bike will do fine in snow, but there are times when I need some ice stability as well.
Why do they have to be tubeless? On UST rims you can remove the valve and put a tube and regular tire on. That said, Nokian Extremes aired up with Stans goop or similar would be mind blowing winter tires! However, I don't know if I would trust them at cold temps as the goop might freeze, crack, allowing the tires to loose air.

Really? That works? These are my first tubeless rims/tires so I'm not familiar with them.
Presta valves. The rims say, "OSB (Offset Sport Bed)" and "Race Disk - Tubeless". They're significantly thinner than the 26x2.2 tires mounted on them.
