After owning the (2012) Audi for about 8 months, I had been a little disappointed with the level of road noise on poor surfaces (particularly rough /worn asphalt at high speed on the motorway) being transmitted through to the cabin.
Needing to replace the original Pirelli P Zero front tires due to wear at 19k miles, I chose the Goodyears specifically due to the low noise rating, although I was unsure whether low external noise would translate to reduced internal noise. They turned out to be a revelation - far quieter.
Recent 200 mile motorway journey London-B'ham, set at usual cruise setting, returned identical fuel figures to the Pirelli's, but noise reduced significantly making the journey far more relaxing. On porous asphalt the car is now silent (just a whisper of wind), on the worst bits of worn asphalt just a gentle rumble instead of a roar.
Since owning the car the fronts have had 4mm or less tread, so I don't know if the noise reduction is just new vs worn tire, or really a function of the Goodyears, but I'm (almost) looking forward to replacing the rears when they wear further, although I suspect the impact will be reduced as I believe most of the noise transmission comes through the steering gear.
As noted above fuel consumption seems the same as the Pirelli's, and my driving style makes no demands on "performance" so cannot comment on these areas. Quattro drive always feels secure anyhow.
Too soon to tell how the tires will wear, but 19k on the Pirelli's was poor I feel.
