Goodyear develops new 'Spring Tire' for space exploration

From Autoblog: Goodyear develops new 'Spring Tire' for space exploration
Goodyear is getting closer to the next generation "tire" that could be used on wheeled rovers for space exploration. We highlight the word tire because those on the original lunar rover were made of piano wire with treads made of titanium cleats – no rubber, no air. A few years ago NASA began work on a new tire, the project another co-development with Goodyear, which made the originals.

The modern version is called the Spring Tire, so-called for the 800 load-bearing springs that make up its bulk, mounted to a six-spoke metal hub. The springs can conform to the varying terrain of other planets and satellites without transferring undue shock to the vehicle, and a malfunction is likely to damage only a few of them, leaving the tire operable.

See below for more info from Goodyear on the tire, and check it out in the gallery of high-res photos. When it's time for another group of astronauts to go "ridin' dirty," this is likely how they'll do it.
