Normally we get -20 or colder and all seasons just don't cut it( to hard). I have 225/40 -18's for summer and super soft blizzaks for winter. I have tried 3 different tires for winter these are the best so far. What works in cold temps get pulverized on dry pavement. Tests have shown that a soft winter tire is better for cold weather wet or dry braking than an all season or summer tire under the same conditions. I take safety super serious,we have lots of poor drivers here and avoiding them is tantamount.
