benzman is correct. I fully expect that the problem will be a tire. I also expect that your tire store balanced these wheels statically without using weights on the outer plane. This causes the wheel to wobble and will then in turn cause a tire to roar.
The tire stores insist on doing this so there are no ugly weights on the outboard lip of the wheel. You can use tapeweights on the insided diameter of the wheel as far outboard as possible. It takes a little patience and a slight amount of brain power, that's why the tire stores usually don't do it.
