Excellent tires; formerly, there was a Spike 01 bridge, however all of the spikes in that bridge were deformed and flew out after only one season. On this rubber, one of the spikes flew out throughout the season, the driving style is highly vigorous and the mileage over the winter is approximately 15,000 kilometers, I got into a hole and bent the disk, and the rubber withstood everything. The only drawback is that the grooves in the center are a little bit small, which makes paddling in extremely thick snow a little bit more difficult than it would be with a Bridgestone. In general, I couldn't be happier with the tires.
