Tyres for ice

Must have happened to lots of us in the past. Hope you mend soon.
Begs a question I've thought about asking before: assuming we do cycle in such conditions (by no means a 'given': I'd swap ice for a cycling in a good thunderstorm any day) - are we better cycling on wider, more tready tyres? Would it make a difference to the stability of the bike and rider? I ask because I keep my mountain bike on standby through winter for use in the snow in preference to my road bike, but haven't used my mountain bike it when it's been icy.

Thanks. My last "off" was a couple of years ago in similar very icy conditions. I took my mountain bike, thinking the wide treaded tyres would give more grip. They didn't. On a fast left hand corner the bike just slid away from underneath me.
Generally speaking wider tyres and lower pressures give better 'grip' on ice. What you're aiming towards though, when choosing tyres for ice, is getting a lot of tread pattern on the ground/ice. The more edges in contact with the ice the better. Whilst knobbly mountain bike tyres are going to help on loose surfaces like mud and snow they are not much use on ice. Also, soft rubber is better than hard.

You see that there is a finer tread pattern on the 'sticking out bits' (knaster in norwegian, forgotten the english word). This finer pattern expands under your weight and prevents*, to an extent, sliding. (*Or rather discourages).
Of course, the studs on this tyre help too!
But, remember, whatever tyre you use on ice you are going to wipe out if you take corners at speed.
