Is it the tires or a rod


That sound more like tires, a rod would be making a loud knocking noise at all times and increase as the RPM's rose, as it happens at such a low speed it could be a broken belt on a tire and if that is the case it is not safe to drive very fast, I would recommend getting the tires checked ASAP as a blowout could happen.

The lower the speed the more likely it is to be tire separation like tennisshoes said. The tie rods on your car tend to squeak when turning and set the steering wheel off center randomly.
