Unfortunately not the case. Tires go through lots of heat and stress cycles. I think most of the heat a tire generates isn't from friction with the road, even.

Unfortunately not the case. Tires go through lots of heat and stress cycles. I think most of the heat a tire generates isn't from friction with the road, even. It's internal friction within the tire itself. The carcasses are made of wires/meshes/layers of aramids/steel/aluminum and aren't indestructible, even if durable.
And the rubber on the sidewalls gets degraded by sun/dirt/sand/etc, too.
- mikepurvis 5y agoTrue, true. 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.
