Below are all the data points for the 2021 ACE / GTU Summer 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.
When in a test Goodyear loses to Laufenn, the test is "Lauffennaghable". (pun intended)
Smooth ?
What some odd odd test results! Among many items, I noticed that in previous same size tests the Falken and the Nokian always had great scores (if not the best ones) in what noise is concerned, but not in this one, apparently! And that's a very easy item to assess... I wonder how would have they overall rated the Michelin Pilot Sport 4, the Goodyear Eagle F1 Asym 5, the Pirelli P Zero PZ4 or even the brand new Bridgestone Potenza Sport!
Even in this - weird - test the Falken FK510 performs well; very consistent tyre in all conditions/sizes/reviews.
Shame they didn't test the (updated) Kumho HS51 or PS71...
I've always said cross reference everything. Tests and reviews, then you find the consistent tyres. Each facility has its own surface, climate, and local airborne matter (which settles on the surface) which combined can change results.
Users tend to be a useful counter also, and provide some whole-life info.
Fully agreed, however on the point that "each facility has it's own surface" etc, this was tested at the Contidrome in Germany which has probably done more tests than any other facility!
Indeed, was just meaning in general ?
I can only say: Don´t use the GTÜ-tyre-reviews as reference. Since years it´s unusable
Every test has it's uses, and it seems this is a great test if you want a tyre that excels in aquaplaning performance at the expense of everything else!
Nokian Wetproof in all test so far wasn't a tyre with good aquaplaning results , this time is excelent.
I always take a look at the results in the single disciplines, if possible. So I can choose my favorite tyre.
And nah, GTÜ show since years very strange results, maybe it´s useful for fans of weak, cheap tyres if the tyre looks good in GTÜ. But for others it´s jeust confusing
