Below are all the data points for the 2013 AMS Sports 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.
There's only 3 sport winter tires in this "sport" winter tires test (WinterSport 4D; UltraGrip 8 Performance & Sottozero 3)! The other (TS850; Alpin 4; WRD3...) are standard winter tires!
I totally agree. Performance winter tires can not compete with daily tires. There is no TS850 for 18" wheels for example. But there is 17" Ultragrip 8 (not Performance) and it's the competitor for TS850. Ultragrip 8 Performance competitor from Continental is TS830P. "P" indicates performance here.
This test is not objective!
