I know the op might not be here anymore, but for others here: I recently had the chance to drive two identical specked 2024 A3’s, both built within a month of each other with identical speck, 1.5tfsi DSG, with very similar mileage. The only difference was one was running a set of new Bridgestone Potenza Sport, the other was on a new set of new Goodyear Eagle F1 Asymmetric 6. Both were on 235/35R19 V91 After driving for over a month on different road conditions both cars, the difference in tires was quite noticeably different. The Goodyear were noticeably quieter and felt more comfortable on our rough UK pot holed roads, the Bridgestones by comparison felt harsher and noticeably noisier, handling wise, not that they were pushed to their extreme, the Bridgestone felt better cornering in the dry, but I personally preferred the Goodyear in the wet on the bends. I was not expecting to notice much difference between the two, but a difference of tire brand made the cars feel completely different to drive on a daily basis, the Goodyear were far better for me.
