They probably left the sidewalls off to compensate for the additional weight of the "spokes". Any mention of how much they weigh?
even beyond that though, these things will replace the wheel and tire at the same time. can they weigh that much? the way the internals looks, they could, but given the physics put into the inner structure, allowing them to be able to build that strength with possibly less material than we might think.
i, for one, think they'll weigh less than most options out there.
