I've got the duratracs also, I don't live in the snow but have taken them up to Flagstaff multiple times this winter and they worked surprisingly well, even in 3-6 inches of snow on a dirt forest road with ice underneath, they gave me the traction I needed. No problem. :thumbs up:
Edit: just saw you are running 37s sorry about that, yea they only make duratracs up to 35...
