Below are all the data points for the 2018 Auto Review 225/45 R17 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.
I think of the PC6 as a class rival of the Primacy 3 (or 4) & the PS4 as a class rival of the SportContact 6; so: a strange matching I suggest.
The PC6 replaced the SC5 in smaller sizes, and PC5 so it covers both the Prim4 and PS4.
The SC6 is up against the PS4S.
It's all a bit of a naming nightmare!
It certainly makes it hard for testers to compare apples with apples.
