    There is Michelin’s Tweel concept but it takes a huge cost for additive manufacturing required to manufacture it since it has replicate the cushioning and dampening aspect of tires. (Or else the ride will be bumpy as hell). Only NASA uses it for the rovers and stuff coz it’s about $20k for each wheel of 4 in width.

        It’s rubber mixed with carbon fiber and other processing oils plus wax for oxide protection plus sulphur and with which it’s vulcanized.
