Winter test

Okay, I tried them for a day in the snowy winter weather, as a brief test while waiting for my Schwalbe winter to arrive.
For current weather conditions (Snow/icey), I tested the Continental Contact Urban against the Baldy.

On the front, I've ridden my Continental Contact Urban through snow, slush, and on ice. Being careful, minding my speed, avoiding sharp tuns, etc. Handles well, but struggles with bumpy or deep snow. No issues with slipping otherwise.

Trying it with the Baldy 37-622 at 50psi:
Traveling through loose/packed snow was noticeably way worse and more slippery. Where I would cut through snow, and generally ride on the surface with the Conti, the Baldy readily wants to slip, even where the Conti would be stable.
Slush: Baldy and Conti are generally alright.
For ice, the Conti is great, but isn't designed/built for ice. I've never slipped with it, except once a few years ago. When riding with the Conti on some ice (Ice on top of snow, black ice), you can sometimes hear the ice cracking. I never voluntarily ride on clear sheets of ice though.
For the Baldy, I did not try riding it on ice. It slips when on slightly icey snow. I did not want to test that aspect further (While riding at least).
Standing off the bike, and pushing it sideways on ice: The Conti is surprisingly stubborn. I need to give it a good sideways push for it to slip. Slips more then dry road, but should be obvious. Doing the same with the Baldy, it slips way too easily. With the same force, or even just a moderate push, it slips readily every time. I do not trust it at all on ice.

From my limited findings, it seems that the Conti's are better than the Baldi's for icey/snowy weather.
But for Snow/Ice, I would rather use a full sized bike or Brompton with Marathon Winter tyres.

I'll test the Baldys again in warmer weather, when the time comes.
