If its ice packed snow you could gain traction and not tear up the links but on black ice I would only use them long enough to say get up a hill or short distances.
You could also look into sipping the tires, I think tire companies charge about $10.00 a tire. We get alot of black ice in the Pacific Northwest and many people who dont want to pay for studded tires get their tires sipped.
