Below are results from the Norwegian Automobile Federation (NAF)/Motor.no winter tire tests. Their annual winter tire testing program is by far the most comprehensive of its kind on the planet.
Every year they select a group of studded and studless tires from various manufacturers and put them through an in-depth series of tests in a variety of winter road conditions and driving situations. Each set of tires is evaluated in the following categories:
- Braking
- Acceleration
- Handling
- Road feel
- Stability
- Noise
- Rolling resistance.
Individual scores for each category are tabulated on a comparative scale. Total scores are then calculated from these results and represent the best overall tire performance.
Both indoor and outdoor testing is used and a variety of ice conditions and temperatures are used to generate the results. Tires are purchased independently at the expense of the test group. There is no tire manufacturer involvement in these tests; it is independent and unbiased.
