I used these April 21, 2013 at a Vancouver, British Columbia autocross event. The weather ranged from sunny to cloudy, damp to rain, and the tires stuck like glue in all of it. I was expecting them to not do great in wet conditions, but as long there is no standing water/puddles, the tires are great. They do hydroplane above 90 km/h in standing water, but I've had slightly worn all seasons that performed worse. There is a lot of tire noise at speeds below 50 km/h, but it gets less noticeable at higher speeds. The ride quality is also not great, but high noise and low ride quality is expected in a tire with capabilities as high as this one. The tread wear from autocross appears to be better than the Kumho Ecsta 4x all-seasons I used in very wet winter autocross events. I highly recommend these tires for anyone looking for a new autocross tire.
