I have the same issue as you. I have the same setup as you. I replaced them back in November (daily commute is less than 18 miles) witht the same tires. then took a long trip in Apr to Atlanta (1700 mile trip total). On the way back I start to hear road noises at certain speeds and certian pavements are louder. So I took it in to have it reblanced. The tech wouldn't rotate them (swap them left to right, since it's staggered). The Bridgestone is NOT uni-directional, so I am curious why he didn't swap them left to right. He claims it's the front and back is more important and left to right is insignificant. what do you think?
Also took a trip to Chicago (800 mile round trip). The noise is usually there from 40 to 60, (not as loud as before I had the Dunlop replaced), but at 90, it's not so loud.
This is driving me nuts. Am I just SOL? I am thinking putting the non-staggard 19's which I currently has winter tires on them. Just change them to all season. Thoughts?
