I think for me, if I needed studded tires, it would depend on how often I expected there to be snow/ice on the ground, and what duration. If there was slick stuff more often than not, I would probably just keep the studded tires on the bike. If I only had one bike, and conditions were variable I'd probably want to swap out the wheelset rather than changing tires all the time. But the ideal situation is to just have two bikes set up for either condition.

Hey New London CT, I'm guessing you've seen Casey Neistat zipping around there on weekends, or you probably know of his dad's restaurant Muddy Waters Cafe.
