Answer
Roy

As a diagnostic, move the tires to the front.  Did the noise move as well?  If it did not, then the noise is coming from  the vehicle and you'll need to have someone look into it.

If the noise moves with the tires - and with that low of mileage -  I'm going to guess the tires did that from the day they were applied - and that means it is strictly in the tread pattern.  The only thing you can do is go back where you bought them and complain.  Maybe they will replace them with something different.
