For this investigation, Auto Bild have bought eight 245/30 R20 tire patterns and placed them through the usual array of wet and dry tests using a Mercedes E Class.
While the internet favourite Michelin Pilot Sport 4S takes its traditional top spot, there is a strange result for the Continental Sport Contact 6, a great result for the ten year old Goodyear Eagle F1 Asymmetric 2 (not 3!), and Bridgestone make a return to tests with the old Potenza S001.
Read on for the full results!
Dry
In the dry the Michelin and Vredestein duke it out for the top spot. The Vredestein Ultrac Vorti R often proves to be an excellent dry weather tire, with good grip and excellent feedback, and it proves that again here, fastest over dry handling and second best during dry braking. The Michelin has a 0.7 metre lead in dry braking, which is comparatively large when you consider only a metre covers the next four places.
The Nankang finishes last in both tests, a huge four metres behind the Michelin during dry braking, which when braking down from 62 mph would be the difference between stopping, and a 25 mph crash!
Wet
The wet testing shows the strength of the Michelins all round ability, with the Pilot Sport 4 S winning both the wet braking and wet handling tests. Its dry weather rival, the Vorti R manages a strong wet lap, but slips in the wet braking testes to fifth. The Nankang again finishes both tests last.
Aquaplaning testing as very different test, with the Nankang winning the test by a considerable margin, the Michelin only managing third place and the Vredestein finishing second to last.
Environmental
The Continental proved to be the quietest tire on test, but it also used the most fuel. The Michelin Pilot Sport 4 S was the nosiest.
