Turbo Trainer little vibration

Hi, I noticing a bit of shaking vibration with my Turbo Trainer Cycleops fluid 2. Is this normal? It doesn’t seem to be affecting anything but just worry some problems in the future
Please watch video showing the issue:

Looks like it is following the tyre, maybe a bulge on the tyre, perhaps tube is twisted inside, also where valve enters the tube it may have a small bump or recess, depending on the tube. Latex tube, for example, they overlay in the valve place essentially creating double wall tube which does not stretch as well as the rest of the tube.
