Also in Upper Michigan? I've never driven with all weather tires in icy weather but it has to be incredibly dangerous. There are non-studded winter tires that have a different kind of pattern suited for snowy roads but on icy roads such tires are positively deadly unless you slow down to a crawl. Are those what you call all weather tires? Even then, hills can be dangerous because you don't have any traction without metal studs or without chains on.
