    That's a lot of dough; back in the late 80s early 90s we used to make our own using sheet metal screws and old knobby tires. Worked a charm, as long as we were on ice and snow, not so good on the odd patch of pavement (road). We modified our approach a little and put the screws just along the edge of the tire so that it would catch only when the tire angle would become extreme. I don't commute in winter these days, just the odd fun ride on the river (it freezes over around here).
