If you want something that is a OK on pavement as well:
Dunlop Trailmax Mission - works good on pavement and on gravel. Long lasting as well.
It is a very stiff walled, heavy tire so it should handle the ST's weight OK.
Don't let the tread pattern put you off. It just works. I have one on my Tuareg. Went to Tuktoyuktuk and back. 6,000 miles of pavement and gravel/dirt and I still have quite a bit of tire left. Not great in greasy mud, but then what is?
I was impressed with the pavement performance which was a bonus.
