I live in a sunny climate (California), so I’m genuinely curious: would the solution to icy roads be winter tires? And does winter tire == snow tire?
I understand studded tires are also an option, but I think their use in this state is heavily curtailed or outright prohibited because of the damage they inflict on the road surface.
I don’t think I’d ever want to tackle ice in an automobile, although I’m told studded bicycle tires are very competent in winter and don’t have as many performance penalties as their car equivalent. I’d probably try that at least once in this lifetime.
