I recently bought Nokian M&G's. They're a fine tire. I can ride in the ice and snow. But if I was going to do it again, without a doubt, I would buy the most aggressive, highly studded tire I could find. Probably the 294's.
I bought the M&G's because I figured they would cut down on rolling resistance. With studs you are going to have resistance anyway, so why not get all the traction you can? When I'm out riding I do not want to fall. Anything that will keep me upright is worth it.
Maybe I can sell he M&G's and get the 294's.
