I skated 3 seasons without thinking much about what was ahead on the road - the tires gave absolute confidence in the behavior of the car. Now, by the end of the fourth season, I don’t feel so confident in porridge, it’s time to change, but I had to choose - summer or winter . As a result, I chose summer - I still need to live until winter . In extreme cases, 5- I will drive more carefully next season. And yes, spikes - 85 percent are still in place. Nordmans generally have series 4 and 7 - excellent wheels.
