The only worry I have as a new commuter is ice, at what point do you reach for the car keys? I don't have studded tyres, a possible investment if it looks like a prolonged period of ice and snow is forecast, I can't justify a pair right now. Currently running on spesh espoir sport 700x30s. Should I be too concerned about Ice and snow of just mtfu?

But previously I'd just get the disc braked MTB out (fitted with very knobbly tyres) and go a bit slower/gentler.
