Good tires for the province, where there are problems with cleaning roads in winter. They didn't let me down. Two winters without losing studs. The third winter I exploited in Hong Kong, where there is almost no snow - spikes began to pour. Changed to non-studded. I am attaching a photo after 3 seasons of operation (about 15-20 thousand km).
To help provide a visual component to my review, I've included some photos.
