Run in as expected - the first 500 km no sudden movements, the speed is not higher than 80 km / h. For the first two seasons, there were no complaints - at 130 km / h I didn’t even notice that the most natural skating rink was on the road, for the third season autumn was warm - spikes climbed, namely, the spike rubs the base and the tire starts to slowly lower, one of the tires has a defective spike never found, had to put a camera. By the end of the third season, more than half of the studs were lost, but the tread height and the condition of the rubber are good - I gave it for studding. For the fifth winter, it became bad to keep, once at 80 km / h on rolled snow on the highway it was blown into a ditch, fortunately without significant consequences. By the end of the season, I noticed that the rubber was covered with cracks. The total mileage was about 35 thousand km. At positive temperatures, especially above +5, it floats noticeably, the car shakes when braking, side wind. With regards to noise - it makes noise, yes, but where to go? If you want silence - buy Velcro. For 2-3 seasons - a great budget option.
