No, thanks for the response but just to be clear there can be a whole load of letters and numbers after the size on tyres, and for example the Michelin Pilot Sport 4 's I had on my last A3 2.0 L Quattro sport were 225/45 ZR17 (94Y)
Tyre manufacturers can make tyres specifically for a manufacturer and I think as OE for Porsche they have an N in the code, I have heard you can get in to trouble with insurance if you don't fit N's to a Porsche.
Did Audi fit Pilot sport 4's to the S3 as original equipment ? and if so can someone read me the code please?
I have a particular reason that I have to order the correct tyres.
If I had a criticism of the Pilot Sport 4's I would say that they were a bit on the noisy side, so to call them Acoustic seems a bit odd!
