I actually bought the primacy 4 ST version, pretty damn quiet comparing to my old michelin energy saver tires.softer, at least 75% quieter. more comfortable, has more grip, theres a split second once u start turning, where there is a lack of feedback from the tire, prolly due to the higher profile tires n softer compound. Overall pretty darn good
