Trailrakers work well in snow, especially 1.9″.
I have Ice Spiker Pros for when it gets compacted/icy. The draggiest 12 mile commute in history. Each way. Just for the satisfaction of taking phone calls from colleagues who can’t get in from 2 miles away as they can’t get their car off the drive.
The one and only expensive bike purchase MrsMC has ever encouraged, after I staggered through the door a few years ago having slid along an icy road with my bike helmet bouncing on the tarmac, narrowly avoiding oncoming traffic, and then ridden the next 9 miles very dazed and confused.
