It's snow and ice in Denver today - almost went rubber side up 3 times on my commute this morning. I'm interested in experiences and recommendations for studded tire options for a shortish (6 to 12 miles, depending on time available) commute. Based on bikes and wheels currently in house I could do anything from 27.5x4.5", 29x2.6 or less, 27.5x3 or less, or 700c x 35-45. Is wider better just to put more studs on the ground, or is there value in a narrower tire that will cut through the slush to the firmer ice below? A studded tire would add to my fat bikes capabilities, but i'm also not keen on pushing that huge wheel on pavement or spending $200+ per tire.
