Tires used in super mileage competition....

Michelin makes a special tire in France for the eco-marathon races (these aren't available to the public, not easily at least). It's clincher bike tire but, it's a radial ply. Crr is claimed to be .001 (1kg/ton) and if I recall inflation pressure is somewhere around 50psi (as opposed to a skinny road bike tire which is >100psi).

The tires are super light and super flexible, but VERY susceptible to puncture. I'm not 100%sure of the name, but I've always seen them referenced as eco-marathon radials. They're identifiable by their wide rolling surface and light blue sidewall ( - random google picture with them)
Cars have not created a new problem. They merely made more urgent the necessity to solve existing ones.
