I mean, these new tires do deform with the ground. That's the "revolutionary tech" they brag about; the rings are designed to compress a bit and deform to compensate for impact, but always bounce back to their original shape no matter how much force is exerted on them. So you get a simulated air pressure.
They aren't saying they don't. The foam and gel tires they mentioned also deform with the ground. Like you said, the rings only compress a bit at the site of the impact. Person you're replying to is pointing out that pneumatic tires disperse this impact across the whole tire
