Every year Autobild Sports Cars aims to go big, and this year they've literally have, testing UUHP summer tyres! In search for the sportiest performance tyre, they used a Mercedes AMG test vehicle which is fitted with 265/35 R19 front and 295/30 R20 rear tyres.
As usual the excellent drivers at AutoBild put seven sets of UUHP / maximum performance tyres to the test in the dry and wet, as well as testing the rolling resistance and noise levels of the tyres.
It's a good bunch of tyres, and includes the brand new Vredestein Ultrac Pro (which replaces the Ultrac Vorti) against the very best in the category.
The Bridgestone Potenza Sport was the best in dry braking, ahead of the Michelin Pilot Sport 4S and Continental SportContact 7.

The Michelin was the fastest around the dry handling lap, but the Tyre Reviews favourite, the Goodyear Eagle F1 SuperSport got the best subjective marks. The Bridgestone overheated after a few laps and had very high wear, something Tyre Reviews has noticed many times.
