Most of the tires with aggressive thread patterns tend to be loud (especially as they wear) but these have remained quiet and they're about halfway to the wear bars. I don't think they're "touring tire" quiet, but they're quiet for a high performance tire.
Don't even think about driving in snow or much less ice though. I already tried and it was the most terrifying drive home i've ever had, although i did manage to avoid hitting anything or anyone.
Lastly, i don't know if this holds true across the entire GS-D3 size range but my tires are a bit wider than the Dunlop's they replaced even though they're the same size.
btw don't buy Dunlop's, they suck! at least their performance tires do.
I absolutely love my Yokohama Advan S.4's. They are a very good handling tire, much quieter than my original Conti's and softer ride. They are not an extreme performance tire but for all around performance, I love them. They have a longer tread life as well as many out there so with the mileage you drive, you may want to seriously weigh them against other options.
