But from the picture in the article, it sure looks like there's a heck of a lot less rubber overall in this tire— so regardless of what it's been historically, this is a step toward a tire that "consumes" way, way less rubber per X distance of driving, whether due to less rubber being in it overall, or it being able to be recharged with additional tread before being disposed of.
