Used Schwalbe Marathon Winter studded bicycle tires with lots of life left, no missing studs. Size 700x35C. Price is for the pair. 

These are great for commuting during the second half of winter when the roads and intersections get really icy. 

I also have a winterized bike to go with the tires, but wanted to give it a tune-up before selling it next spring. Let me know if you're interested and I'll get it done sooner.
