I didn't notice much difference in the road noise, but then again this was on an open top heep that doesn't see much highway time. When it did get on the street there was so much other noise, wind, exhaust etc., that tire noise changes aren't very noticable. But then again, I'm one of those wierdo's that like the sound of an agressive tire on pavement
