2,000 miles on the tire. I will measure tread depth and do a video review later this week. Just got back from Sunday River in Maine. On the drive home I encountered some bad conditions. Only about an inch of snow but it was icy, accidents, cars fishtailing on the road in front of me, yet I stuck like glue on these tires. Their performance on snow, ice, and rain is superb. The conditions changed to rain for about 200 of the 250 miles I drove and they do just as good a job sticking to the road and I have had no problems hydroplaning. Tread depth after 2,000 miles just under the original 12/32nds but not quite 11/32nds.
