Highway Speed Vibration

I've a 03 EXPY XLT with just over 24k miles on it. For the last 15k miles, I've had a vibration/low freq hum when approaching 60mph then deminishes around 70mph. the service center can't seem to find the cause. I'm wondering what the cause could be and it maybe it could be the U-joints or even an unbalanced drive shaft. I had that problem on an old 69 chevy stepside. AFter reading some other threads I wonder if it could even be the Continental tires. Would appreciate your thoughts. thanks.

I would first suspect the tires. I get all kinds of weird noises at different speeds with these tires. I've deduced that that is the only thing it could be.

I would second the tires and change them ASAP. It may cost now, but it could stop a seperation of tread that will cost you a lot more. IMHO

Tires huh....haven't really thought of that one. what's the chance that all the tires could be doing this? could only one cause vibration like this? it's coming up on rotation time, I'll see if the vibration is still present after that. thanks.
