Winter isn't the time to ride hard. Dial it back. You really shouldn't be aiming for knee dragging angles on the street and with your lack of proper gear during good weather in the first place. You're pushing too hard and asking too much for no good reason in my opinion.

Your bike will tell you "F*** off" and toss you if you keep that up

Lower than that, and the tire is going to lose more of it's shape. Do some experimenting, find what's best for you.

But I have to echo Kuro here, don't push it. Have a nice ride by all means, but don't push it.

Cars leave ruts in the ice and snow and that's quite dangerous to navigate on a bike, especially a road bike.
