I had the Goodyears on the first D4 and wasn't a big fan due to the noise they created on certain surfaces, although they lasted fairly well and I stuck with them when I needed a new set.
The V8 D had Pirelli's which were Ok and I was up to around 16K on them when I traded her in so they lasted fairly well but again had a harmonic noise on many road surfaces mostly A /B roads around the speed limit officer
The S8 was fitted with F1's and so far they have proven to be a match for the car and it's performance so no brown pant moments
Can't say too much for wear as I haven't done 4K yet but they look fine and the harmonics are sufferable. Even my wife's A3 ragtop gets the same humming harmonics on the same surfaces with 18" wheels fitted so I guess it's something I will have to put up with. I have found setting the exhaust up for full noise creation and sticking it in sport regularly makes me forget about tyre noise all together. I am just glad they are there doing their thing really as that's all that's between me and the hedge most days
