Here’s an interesting question then. Had this argument with Thumper years ago about tyre width. He maintains that the skinnier the tyre the better. A narrow tyre for example will be better on snow than a wider tyre. I can see that, but also if you have 2 narrow tyres then they would be better than 1 narrow tyre. So put 2 narrow tyres together and you get a wide tyre!
Phone in work sick and dont bother trying to ride in snow or ice. I had to do it in my apprentice days.. both feet sticking out off the pegs just in case, and staying well inside the tyre tracks.. definitely not fun!
