I ditched them this morning. That's only because we've had no precipitation for a week and the road has been clear and dry. The lower than normal temperature is keep the snow and ice solid, so no melting during the day and frozen puddles in the morning. Sooo nice to not ride on studs. I even gained back the 3-4 minutes it took to swap them this morning, and more.
I don't expect this to last though. It'll be another month, at least, until the studs are put away for the season.
