Having never been to the USA, I'm not familiar with your road surfaces but believe they are asphalt and concrete?
We have asphalt here in NZ with some surfaces really rough with small sharp stones and others quite smooth. You can see from the photo the thickness and texture of the asphalt.
I run a Bridgestone Exendra max on the rear and get around 10000kms on these roads.
I must add...this is after one of our recent Earthquakes along the east coast of the South Island.
