Snow tires are great, but IMO are unnecessary if you live in the Denver metro area. Dry pavement wears them like pencil erasers and the Front Range really doesn't get all that much snow. Hell, even up in the foothills I wouldn't have them. Just not enough days with snowpacked roads to rationalize them. I wouldn't have them unless I lived west of the divide in the mountains. That's when they'd be practical IMO.
