Bought these for my 2005 Audi A8 (D3) to replace the very noisy Bridgestone RE30's that were on the car. My main concern with a replacement tyre was road noise (since the A8 is such a quiet car, road noise from the tyres is more noticeable). The Kumho's were indeed much better for road noise (quieter), and with the softer side walls compared to the Bridgestones, bumps were less intrusive.
I had two on the front of the car fitted in Sept 2011, then two fitted on the rear in May 2012. The rears are still pretty much new, but the fronts (understandably) are now around 3mm after approx 12k miles. The only issue I have, is that both front tyres have worn out completely on the outer edge (more noticeable on the passenger side than drivers), to the point that it's now smooth. The tyres are still legal, due to the tread pattern being complete and above the legal limit. I've had the tracking checked, and is okay. The tyres are always inflated correctly too.
I find it odd that other people on here have written the same in their reviews too.
