I got the first pair in 2022, and in just two seasons, I had worn down 40% of the tread and half of the studs. After a 20,000-kilometer use in the third season, air began to leak out from behind the spikes on both wheels simultaneously. We replaced them and are done for the year. This season kicked off with the same problem as last, despite the tires appearing to have normal tread and being able to roll for at least one more year before needing replacement. I skated for seven years on my first set of winter tires from a different manufacturer, so three seasons seems like a real bargain. In 11 years, the car's odometer read 148k.
