I have had these tires since 2022 and during this time they have not changed much - the rubber has no signs of wear, the spikes are in place. I used a lot of tires, the driving experience is great, but only these give confidence and deliver comfort while driving: very good grip in deep snow and smooth ice, on dry pavement - predictable, but my past VRX clutches are inferior. They do not skid in snow porridge. Best for snowy northern winters.
