Tyre manufacturer Michelin has presented, and created, a concept tire made from bio-sourced and biodegradable materials using 3D printing. The tire is airless and is designed to last as long as a vehicle.
Its ultra-durability comes from its honeycomb structure, which is inspired by natural models, mimicking the natural growth process at work in a plant, mineral or coral.

The tread of the tyre can be replenished using a 3D printer, meaning that it can be altered to fit alternative terrain or to simply replenish the tyre after an amount of wear.
Michelin says that the Visionary Concept communicates with the vehicle, and the vehicle communicates with it. Without getting out of the car you can be informed of the wear on the tread and program a reprint, choosing the type of tread pattern needed at that particular time for the intended use.
I’ve posted about this before but there’s a reason Carthaginian coins are minted in Greek weights; it’s because they were paying European and North African troops with them, and those troops wanted Greek coinage because the values were already known, regionally.
Prior to that, no Phoenician city, as far as I know, minted their own currency, making them the only Semetic-speaking peoples in the Ancient Mediterranean/West Asia to not do so, as far as I know. It also explains why the coins don’t have West Asian (Mesopotamian) names and values/weights.
