Hi, Quick one from me - just purchased a 2021 Audi A3 PHEV and I can agree the road noise is really bad, and I will be changing the tyres straight away. Previously I had a BMW Z4 that was on Bridgestone run flats, which incidentally are the same make as my Audis, the ride was incredibly crashy and harsh so decided to change them for comfort tyres and after doing no end of research, landed on Michelin Primacy 4 and the ride quality, noise and more importantly safety was night and day, totally different. On the Bridgestones when taking a corner with less than perfect road surface the car would scuffle (not sure if thats the right word for it) across the surface which I found serious scary (a typically penalty I'm told of run flats) but with the Michelin it was so much better - I cannot emphasise the difference - it was a typically first thing to change within the BMW Z4 community. With that I will be changing these for Michelin Primacy 4 or I might try the Primacy 5 which I would assume are better.
