Tires were hemp-reinfoced plastic, then steel-reinforced plastic, they are now actually fiberglass-reinforced plastic. It doesn't matter. So long as elasticity is provided not by gas compression, but solid material compression/tension, that solid material will deteriorate fast. Downvote me all you want, but this idea won't fly. It can't compete with regular tires at anything above 20mph.
