Just finished 8th (yes, eighth) winter with this set running in Minneapolis/StPaul on a RWD 1999 Mercedes C280, my daily driver on a 10 mile round-trip 5-weekday commute. I bolt them on approx Dec 1 and pull them off approx April 15. Tread is half worn, if even that. Very heavy snowfall this past winter (toughest conditions I've seen in a decade). Tires performed perceptibly equal to first winter (2007,) which is to say excellent. Great value and service. Purchased as a tire/wheel set from Tire Rack in Jan 2007, as their recommended combo.
