A run-in with them was completed somewhere between 300 and 350 kilometers at a speed that did not surpass 80 kilometers per hour. Before these, there was a model called the Hakkapelita 4, and I rode it for seven years. After the fifth zyma, the spikes started to fly out, and in many respects, the seventh season barely skated. However, this was evidently caused by rubber fatigue, and the product had a long service life. After the winter that's coming up, I'm going to add a review, and we'll see how they perform. Got pros: Otezdil once, during the winter, had a perfectly typical flight, but not a single spike was released. Below are some downsides: However, in general, this can be said about all Nokian winter tires. For the winter, I will exclusively buy from this particular company.
