Just put these on for third winter's use -- barely show any wear. Most driving is in greater Toronto area, don't encounter a lot of deep snow. Never a problem. Excellent on both city streets and highway.
Excellent tires but WAY overrated on lifespan. By no means am I hard on my tires and I rotate every 5k-6k miles. All 4 of my current set are almost down to the wear indicators and I have just over 40k on them. Great tire otherwise, but know their limitations.
