I can advise this rubber for Siberia, the North and areas equated to them. The ideal operating temperature is from -18 to -40. Previous driving experience: Nokian Nordman RS-2 , Nokian Hakkapeliitta 4, Yokohama Ice Guard IG55, Hankook Winter I*Pike RS W419. Different pros: Snow is perfect. In severe frost (-35-40), elasticity is restored relatively quickly, which in turn entails excellent handling. Some cons: There is a great tendency to side slip, on winding sections of the road you need to keep your eyes open. End lamellas do not fulfill their function to the fullest. He does not feel very confident in "nyasha" (reagent + snow).
