Hi, Pondman, Sorry my comment was an answer to his original question, comparing Continental ContiSportContact 5 and the Michelin Pilot Primacy HP, I can't comment on those newly launched tyres
As you can see from my thread, I only ever fit ContiSports when replacing, and my exposure to Michelin Pilots is limited to used cars that i've bought - on the SL500 and previously on a 335i (running non-runflats with Birds suspension)
I use the Contisports only because all the professional tests say that their wet weather performance is marginally better.
I'm running a dull E500 and SL500, so I never come anywhere near testing the performance limits of modern tyres.
You're making good points about the Marketing claims, and the issues of running nose heavy 3 litre diesel (I once also ran a 530d and 330d) - all I would suggest is to hunt for comparative tests - because Marketeers sometimes "exaggerate."
