In an unexpected release, Auto Bild have just published their second ultra high performance tyre test of 2021, this time testing the popular 235/35 R19 tyre size and again putting the new Bridgestone Potenza Sport up against the best from Continental and Michelin. Strangely, Auto Bild have included the Goodyear Eagle F1 Asymmetric 5 instead of the Goodyear Eagle F1 SuperSport which would have been a more natural selection for this group, but it's still a really interesting test.
As always, things are close at the top, with Michelin taking a narrow victory, just ahead of Bridgestone and Continental in joint second place.
Read on below for the gritty details, and testers notes on each tyre, and be sure to check out the full test on the Auto Bild website.

Dry braking was led by the often dominant Michelin Pilot Sport 4S, with the Continental SportContact 6 close behind.
