I had the mid-life pickup out yesterday.It runs and handles great,except when I got on the freeway.Speeds above 55mph,there was a vibration.Tires are new and balanced,wheels are straight.This vibration is not felt in the steering wheel, or the seat.It's felt through the floor I think.Any suggestions?

If it didn't have a vibration before new tires were installed and now it does now I would have the tires checked again.
Could be a broken cord in the tire. I have a motto "just because it's new doesn't mean it's right"

:?: If you can swap the rear tires with the front and the vibration still is coming from the back you can eliminate the tire theory.
