I have used studs...
I have a beater LTD440 with Bridgestone M77/78 knobbies and short sheetmetal screws in the outside knobs. I run low, low air pressure and with low seat, low power, and low cost, this gets me through my residential 3 mile commute(<20mins). I encounter mostly thin ice and frozen slush. I will increase tire pressure if I know the roads will be dry. This keeps the studs off the road for the most part but MX knobs on the street are never going to handle great. The tires are not DOT and neither are sheetmetal screws.
