It is a company vision, not a product announcement, so as expected much of it is fuzzy and hypothetical, and it may or may not apply to this particular product.
But this part offers a clearer idea of what rechargeable means:
> The tread can be “recharged” using a 3D printer, which means that VISION can be adapted to motorists’ changing needs, for maximum comfort, safety and sustainability.
They also have an official page for this actual product line, which is called Uptis (Unique Puncture-Proof Tire System):
The FAQ on this latter page says stuff relevant to sustainability:
> Today’s level of rolling resistance is about the same as a zero-pressure (“run flat”) tire
...
> Uptis will have the same mileage of a standard tire.
I believe this is an important part of sustainability because if mileage were worse, you'd gain in one area (reduced waste) and lose in another (increased energy usage). So if mileage really is the same, that's a good thing.
