The winter season is over, all winter every day I went to Cordiant Snow Cross. Bought new ones in the fall. Now, after changing to the summer one, I checked each tire after the season - only on one wheel the loss of 2 spikes, the rest are 100% like new! Moreover, I went without sparing especially. I definitely recommend. I don't know what will happen after the 2nd season, but the first season is excellent.
