Depends, main roads may well be ok, rural ones mebbes not. I've walked my bike to the main road when the road outside has been icy. In snow I'd say the wider tyres are beneficial, on ice? Hmm. My car weighs over 1600kg,has four wide tyres and still slides on ice if I brake or steer in a cack handed way.
Personally I'd prefer two hours on the turbo and a shorter session than planned than two hours out of four on the road and the other two hours waiting at A&E for a broken bone to be treated. It's a personal judgement though, I can't judge your roads or your aversion to a broken bone. Whatever you do, enjoy it.
