Removed the tire on Saturday and checked everything over. I do have a dragging brake caliper, and that (with brake lines/pads/caliper rebuilds) will be my next project. I installed the spare, drove to my local Wal-Mart, and had them balance the removed tire. Was only 1/2 oz out of balance and seemed to be very close to true in round. Drove with the spare up to 70mph, no vibration 0-70. Changed to original tire, drove up to 70mph, and no vibration. Problem solved? I don't think so, maybe just a temp/fluke problem......I'm waiting for it to happen again. I HATE intermittent problems......

With an out-of-round condition, the outer diameter of the tire will seem to move in and out from any fixed position. Hold something close to the outer edge while the tire is rotating. If the tire seems to move in and out more than 1/8 inch, you have an out of round tire. You can also check the wheel for bends the same way--just hold something near the rim while it rotates. Noises could be caused by defective wheel bearings, dragging/damaged brakes, etc. Thomas E.
