I have the Michelin Energy MXV4 S8 on my Altima. The tread on the Primacy MXV4 is very similar, so they should be very quiet. Most Michelin's are extremely round and easily balanced, so don't shake or vibrate at any speed. The Primacy have a better treadwear rating than the Energy so hopefully they last longer than the Energy. Biggest complaints I have about my MXV4 Energy's is that they have worn out very quick (I'm predicting < 30K miles), have only "acceptable" handling and are absolutely horrible in the snow. I expected more for the price I paid.
