Below are all the data points for the 2020 ADAC Winter Tyre Test - 205/55 R16, 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.
Explain this: how is it possible last year with the same rivals, contis to be dominating and this year only in 7th place? Also, how can ADAC not include the inventors of snow tyres, Nokians? Where are Vredesteins and Gislaveds?
It is a strange slip down, as other than the Bridgestone, there's no real new patterns. One reason is that the test conditions this year didn't suit the conti as well, or other tyres have had mid life updates to improve them.
It was also strange for me and I checked the site of ADAC. The methodology is a bit strange. If one of the parameter is significant weaker then the other, the score of the tire get that significant weaker parameter. For Conti-s they are the best or worst second for wet, ice and snow, but get weaker dry score, so the position is according dry. For winter tire not sure that it really need to score tire by that parameter. I was with Nokian WR D4 before (3 winters and last winter I replaced them with Conti 860, all 205/55 R16) and it was a bit strange for me, but the dry grip was nothing amazing, but wet grip was significant better then the Nokian, snow was a little better for Nokians, also with Nokians was fuel consumption and internal noise much lower. The bigger difference for me is the wet, where Nokians was really much weaker - the tires spin really easy and in the winter is very common to rain or just to be wet.
