But, But ,But, if there are tire tracks and the snow is still hard, not slush, I find studs to keep me upright! Those tracks from cars can get you dumped on the ground. If it is a packed roadway in its entirety you may be OK. But tracks with snow in between is bad luck for me. I've rolled around a bit on the snow covered pavement. It was probably funny to those not in the snow. Take care Tom, and Be Well, Bluesfrog.
