I had this problem after buying 8 new drive tires. I had some vibration with the old tires, but nothing compared to the new ones. My problem was found by a mechanic from a different garage, in that I had two wheel (steel) that were out of round.

Once I got two new steel wheels, the vibration was gone.

I learned the importance of watching when you buy tires and get them balanced, to be physical there and watch it happen.

The reason I say this, is because when I took it to another mechanic and saw the tire go on the spin balance, I noticed the wheel out of round before he ever said anything.

Another thing I have noticed, is the smaller garages, will usually let you watch them doing work, and ask questions.

I always ask if it is ok to ask questions because I just want to learn how to do some things. They have all said it was fine, except for the big chain Truck Repair Centers. (For Insurance purposes you are not allowed)

I had this happen a couple of times.

Ditto, I've seen this several times as well.

All the failures I've seen(some MUCH less then 50 miles) have been due to the initial torque being wrong. Torquing isn't the only issue either.

How could it be a PITA? You only need to do this once following the initial install... unless, of course, you were with one of those companies that torque them on a regular basis... that quickly becomes pointless btdt.

I agree... initial torque, or lack thereof, is the major issue... keeping in mind that over-torquing causes many failures as well (ye ole 1" impact gun!). Also, proper wheel bearing adjustment procedures (or lack of that as well).
