The Bridgestones that came on my turbo are unbelievably loud on rough concrete pavement. Anyone know if the Pirelli's are quieter? I've heard on rennlist that the PS2's are quieter but there is one report that they are also very loud on rough roads. Any advice is most appreciated before I change these out (wife not likely to go on long road trips when it's too loud to hear the radio or normal conversation - wait is that a bad thing?)
