I bought Nokian Mount and Ground 26x1.9's specifically because they have the carbide studs that can endure being ridden on pavement. My commute is mostly clear road. But, I cross a bridge every day that can get very icy and I don't plan to chance it. So I just geared down my fixed gear from 70 to 63 gear inches, mounted them up and forgot about it. They'll come off when all the snow melts off next year.
