Had the Perrelli's and swapped them for some Michelin Latitudes. I was searching for a quieter ride, honestly, it didn't help much. They are both awesome tires, the Michelin's seem a little smoother (but they are also new now). But, I should have rode the Perrelli's until they expired. Wasn't worth the upgrade in my opinion and the Perrelli's look better, to me.
