A total of around 6,000 kilometers were skated this season. In terms of value for money, I gave it a perfect score. If cost is ignored, then the answer is 4. High-end tires are superior, but the price is prohibitive for most people. Tires are quiet on asphalt and perform well on snow and ice. Even though I like to staratnut at red lights, I haven't lost a single spike all season. I drove through freezing rain on the highway and didn't end up in the ditch. There are quieter alternatives to the Pirelli Ice Zero, but they come at a higher price. (occupy a vantage point atop a company vehicle).
