Drove them 2 times in January Hong Kong-Hong Kong-Hong Kong. Despite the varied coverage across the regions, the temperatures ranging from +2 to -29, the uncleaned roads, etc., there was not a single issue or potentially hazardous circumstance. Tires are not inexpensive, but the value they provide more than justifies the cost. Over 8,000 kilometers traveled over the course of two winters with nary a single hazardous circumstance encountered, be it in the city, on the highway, or in the snow. Prior to that, there were NF5 gislaveds, and Nokian 8 - I swore to myself that I would never again place spikes. Separately, having the courage to switch lanes at high speed during snow-to-asphalt transitions and having good side grip in corners are both significant advantages. Because 4x4 vehicles have lower acceleration requirements, I do not consider it.
