Anyone here familiar with riding bikes in snow? I live in Northern Sweden and I'm considering buying a new bike with 35mm tires, is that enough if I put studded tires on it, or should I opt for something with more width? I also want it to be speedy in the summer, which is why I'm looking at bikes with road shifters instead of MTB.

Right now I'm riding a bike which has I think 42mm tires (not studded, but with pretty decent grip pattern, low pressure) and it's okay, but there will definitely be more snow and ice in a few weeks.
