Have you tried this? I made one with standard sheet metal screws and discovered how quickly soft metal wears out compared to proper tungsten carbide. Yes, it worked, and it was cheap. But it's worthless after a few hundred miles, while the Schwalbe Marathon Winter Plus I paired it with isn't yet showing noticeable wear.

If you run a mismatched pair (like mine), be sure to run the better tire on the front. That's where the traction matters most.

Materials aside, studs make ice riding much funner!
