Below are all the data points for the 2015 Sport Auto 19 Inch Winter Tyre Test, displaying how each tyre performed across all test categories. The spider chart below provides a complete overview of performance, where one hundred percent represents the best performance in each category. The larger the area covered by each tyre's plot, the better its overall performance.
How to read these charts:
For each test category, data is presented relative to the best performing tire. The direction indicates whether lower or higher values are better - pay close attention to this when interpreting results.
Spider chart cannot be displayed because there are no test categories common to all tires.
You say that the TS850P is 2nd on snow, but with 8.6 and "low lateral stability" he's more like 4th for me:
Pirelli 9.3
Michelin 9
Nokian 8.8
Continental 8.6
So, where is the mistake?
The difference seems to be the magazine weighting, which is probably based on percentage from best, where we based our overview from the 4 categories of snow tests and prioritised braking.
Braking: Conti, Michelin, Nokian, Vred
Cornering: Pirelli, Conti, Michelin, Nokian
Traction: Vred, Conti, Pirelli, Nokian
Handling: Michelin, Pirelli, Conti, Nokian
