They are rated for indoor track use only, which is where they are going.
At that weight yeah I can imagine its just a slither of latex with smear of rubber on it, they are rated upto 205psi and I'd intend running them in the 170-180psi bracket. No idea what they are made of but they are going cheap enough that its worth finding out. If they ride OK and don't immediately explode I might order some more.
