Up-Date
I'm up close to 3400 miles and the vibration is exactly the same. it dose make a kind of humming noise too, always has. Has nothing to do with tire psi I had the tires hard as a rock and every thing in between and the vib is always there.

 

I have about 600 miles on my 2010 FXDC and that pos Michelin "Scorcher" will be gone at the 1000 mile service.

 

Might consider an Avon Storm 2 Ultra.

I like mine. They have 2051 on them and I have no complaints. I have always like Michelin's car and bike.

 

I put 13,000m on my michelins; '10 superglide. Never had a problem with buzzing or shaking or anything for that matter...
Anyone, getting rid of there stock Scorchers???.... How much???

 

I have 5,000 mi on my scorchers, seem to be wearing great. the only vibration i get is from hard parts dragging the pavement. 2010 FXD

update Apr 2012.

at 8000 miles the rear was toast

 

30 front 40 rear. I belive the buzzing/vibration is from the bar and shield on the tire as well like Grendel4 said. It's a little odd at first but you get use to it and it's not a big deal.

 

I'm getting a little noise on my 2010 FXD Michelins going around turns at 4,300 miles but I don't think there's anything specifically defective about them. My experience is all bike tires get a little louder with miles. I'm pleased there's no cupping but the wear rate is only average. My bike's rear tire will be worn out before 6,000 miles.

 

I don't think the vibration is from the bar and shield on the tire. You'll never lean over far enough to hit it. Beside that the vibration feels more like a buzz. Which to me would mean there would have to be many more bar and shield indents closer together to get that feeling.

 

I you don't think you'll ever lean over far enough to hit the bar and shield on the tire you either don't have them or haven't looked at them lately.
