Dealer replaced my front tire a few weeks ago. Bike felt smooth and quiet again. Was great for the vibration to be gone from the front of the bike. Now I started hearing a grown in the curves again, but it was from the rear. Got home and jacked up the bike to look at the rear tire. The rear tire is starting to cup as the front tire. 40 psi checked every week. I can't believe in the year 2009 tire manufacturers can't build a good tire. And we can't even find tires to fit the '09s that we can buy.

 

Yup, same thing for me... HD replaced the front with a D408F this past weekend, but as soon as I got home I too noticed that my rear is also cupping, although not as bad as the front had. But I should still get around 10,000-11,000 miles out of the rear.
