31" vs 33" on a snow or icy road

[Slonopotam]

Hi,

Assuming the same tire width, which tire would perform better on a snow covered (plowed!) or icy highway, 33" or 31" ? How big is the difference ?
I am specifically interested in BF Goodrich All-Terrain.

Thank you

I ran 33s in Alaska for 6 years, never had issue, we drive ice and snow for 5+ months, I did like softer compoud tires in the winter as I ran a swamper.

They are gonna perform the same, only thing you will notice is size
