Vibration at 60mph...

My truck starts making a terrible noise at almost exactly 60mph from the rear passenger side. It sounds/feels like I'm driving on the rumble strip beside the highway. Below 60mph, it doesn't make the noise at all. Above 75 it starts to go away again.

Anybody have any thoughts on what is wrong? I'm thinking either the driveshaft is out of balance or the tire. (I've got 33s) It's been doing this for a long time, I just rarely drive above 60mph.

You can set my truck on fire and roll it down a hill,
and I still wouldn't trade it for a Coupe de Ville.
