I ordered 2 sets of these tires ( both studded, hence the lower dry traction score and noise ) with new steel rims, one set for my brother who has the identical vehicle. I have just over 7780 kms on these, ordered October 15th, installed on the 22nd of October.
These tires are AMAZING in the snow, and equally competent on ice with the carbide studs. Wear seems to be non-existant, however I haven't measured the tread depth. The only downside to having studded tires though is the noise, which is more annoying at lower speeds in town, as well as reduced traction braking and accelerating on dry road in the winter.
With the traction control off, you can break them loose in wet snow, but it takes a bit of throttle to do so. With traction control on, this car is like a 4x4, I managed to climb about a 25 degree incline with about 5 inches of fresh wet snow ( back lane that didn't get plowed ) without losing forward momentum, although the traction light was flickering.
If you live in the snow belt, you need these tires. If you also have a lot of ice in the winter ( melt/freeze cycles + rain and snow ) you need them studded. What a difference over driving most of my life on all seasons.
