warped rim vs. out of round tire

[rh71]

Apparently I have both... a warped rim on the left rear, and an out of round tire on the right rear. I've been having vibrations in the seats at 60mph+ only, as soon as these wheels/tires were mounted (not a bent rim from damage). I had taken it to a Hunter road-force balance place and this is where they showed me. They said the machine only goes up to 20mph and that's where they zero'd out the balance at, but the vibration is still there at 65mph.

My question is what would cause the vibration more? The warped rim where I can see it spinning out of shape on the balancer or an out of round tire that has a hop on it. The tech said the hop can be compensated for on the balancer, but the warped rim is the primary problem. Do you agree? I am going at this one step at a time to see if it gets rid of the problem with the least additional cost.
