For thirty bucks, I'd pick up those tires. Sitting here in a comfortable chair, I'm wondering if the small difference in width would make much difference in snow. (That's an invitation for the experienced to confirm or refute that thought. I'd guess the tread pattern would be more important? :-) Yeah, as mentioned, snow and ice are two different animals. The Greenway last Mon afternoon was all rutted ice, and even a bit hairy with studs. I wouldn't have tried it without, and the only two bikers I met had studs too. Sooo, pick your goals... :-)
