Rode a Polar, then got this one. Therefore, the comparison is with Polar. There are much more spikes, it holds worse on ice (addition - worse in turns, worse starts on ice, brakes better on ice and snow). On asphalt, because of the spikes, the speed in corners is less, the braking distance is longer. How you can make rubber that is worse than the older model, I do not understand. Might just be cheaper though. The composition of the mixture is subjectively worse. When you run your finger along the Polar tread in winter, it seems to be a little sticky, this one is just like rubber (addition - the tread itself bends worse, I tried it on the cheapest kama and on Nordman 7, they have a more elastic tread). Now I'm thinking of trying snowmax, though already in the Tungi brand. Although doubts also take
