Goodyear to develop airless steel tires for GM’s moon buggy: Why these tires are essential?

The floor of the Moon is roofed by a thick layer of regolith mud recognized for its infamous bodily properties. Common wheels work poorly right here, plus the identical extremely abrasive mud decreases the general reliability of the rover’s chassis. One other factor – giant temperature variations negatively impression air-filled tires, making them go flat throughout night time time, and probably inflating until the explosion restrict throughout day time.

Nonetheless, the early roving autos have been made to be disposable. Present era of lunar transportation has to fulfill the factors of re-usability, which additionally applies to tires. Moreover, these new fashions may have the potential of autonomous operation, and which is why their want for servicing must be minimal.
