2021 Sport Auto UHP Summer Tyre Test

It's the second time in history the new Bridgestone Potenza Sport has been tested in a tyre test, and it's super exciting to see whether it can it match the first place from the Auto Bild Sportscars test!

There are some small differences between the two tests. Firstly, Auto Bild tested 20" tyres using a Ford Mustang, where for this test Sport Auto have used the Toyota Supra / BMW Z4 platform which wears 255/35 R19 front and 275/35 R19 rear tyres.

Sport Auto have also added a little depth to the test by including both UUHP (or Maximum Performance) and UHP tyres, which means we get the Goodyear Eagle F1 Asymmetric 5 up against the best from Michelin and Bridgestone, not the Goodyear Eagle F1 SuperSport.

Sport Auto have also provided lots of data about the tyres on test, which you'll see in the results below underneath the images, and it's interesting to see Bridgestone have been punchy with a starting tread depth of just 6.7mm on the front tyre, way lower than the 7.4mm of the Michelin and 8mm of the Goodyear. Please note, the information listed below is for the rear 275/35 R19 size, if you'd like the data for the front size please head over to the Sport Auto website. 

UUHP vs UHP

Analyzing the differences between the best UUHP and best UHP tyres brings up some interesting data.

In the dry, the UUHP tyres from Michelin and Bridgestone were unrivaled in both braking and handling, with the testers also noting they had the sportiest handling on test.

The wet testing muddied the water a little. The UUHP Michelin had the shortest wet braking, but Falken managed to beat the Bridgestone to second place. Falken also dominated the wet handling test, ahead of second placed UHP Goodyear with the Bridgestone having to settle for third and the Michelin down in seventh! Somewhat strangely, the wet circle test brought the advantage back to the UUHP tyres, with Michelin leading Bridgestone, which could mean the water depth on the wet handling circuit was too much for the UUHP tyres at points, as the UHP tyres were the clear leaders in the aquaplaning tests.

Dry

The new Potenza Sport led the way in dry braking with a small advantage over the Michelin Pilot Sport 4S. 

Dry handling matched the first two  positions of dry braking, with the Continental SportContact 6 taking an impressive third place.

Unsurprisingly the two fastest tyres on test also had the best subjectively handling, with the Continental and Goodyear the best of the UHP tyres.

Wet

The top three positions in wet braking were covered by just 0.3 meters, with the updated Toyo Proxes Sport A still struggling in the wet.

The Falken FK510 again proved its wet mastery, edging out the Goodyear for the fastest average speed around the lap. The Michelin Pilot Sport 4S seemed to unusually struggle, posting the second slowest time.

The three fastest tyres also had the best subjective handling.

Michelin improved its wet weather performance by producing the highest lateral G around the wet circle.

The Nankang AS2+ was impressively ahead in straight aquaplaning tests, however that didn't make up for the otherwise low grip.

Environment

The spread of external noise was covered by just 1.9db.

The Continental SportContact 6 had the lowest rolling resistance on test, with the new Bridgestone posting it's first test loss.

Unsurprisingly the Nankang was cheapest, but surprisingly the Bridgestone was actually more expensive than the Michelin, at over 1000 Euros for a set.
