I'd recommend it to others at their own risk. Two studded is safer, sure. But just the front can work.
OP is in Chicago, real winter, for like 5 months. What kind of ice only needs 1 studded tire? The idea is to remain upright. What are you trying to save? $ 60 bucks or so? Vs a broken bone or what? Stop propagating myths.
