Safety not noise....
SPEED BUMP.......I'm on my 6th set of tires because of rear cupping. Factory tire rep sez that all the tire manufacturer is responsible for is the tires safety, not the excessive noise. Now that is a bunch of BS because after 5000 miles one cannot hear the radio! This is one deal that Ford swept under the rug! I've had different manufactured tires on the 01 Focus and they all ROAR! Just grin and bear it they day! Next time I'll buy a Toyota and grin at the FF at stop lights.
