I was very happy to find out that I could get Marathon studded tires in a 30 C size for this winter for my Diverge beater bike, and I never needed to ride my wide, studded-tire mountain bike at all. All my winter (and otherwise) riding is on pavement mainly as a commuter, with extendable routes.

Also nice is that they worked well at full pressure (90 psi). On the worst slippery day, I rode confidently, but had two near falls while walking.
