They do have inner tubes, the hub bolts together and the tube is required
to get an air tight seal. In fact, the HF item page has a link in the
upper corner pointing to a replacement inner tube.

Yeah, I saw the ad for the tubes but I still wanted to suggest making sure
these ones have tubes. I'm good about keeping car tires properly inflated,
but I didn't pay the same attention to my hand-cart and last time we went to
use it the pressure in the tires had become low enough that the tires had
lost their seal on the rims. *Now* there are inner-tubes in those tires.
