I had a set of bt45 and i loved them, up here in the great white north we get cold, real cold. Never had a problem. By the look of those tires they were way past worn anyway. What bridgestone means is they aren't designed to be used in cold temp. Like slicks are not for the street, or......cold weather!
Why don't you get some winter or all season tires if you're concerned?
