For the Lunar Roving Vehicle used on the last three Apollo missions they developed the spun metal wheels.

Ferenc Pavlics was given special recognition by NASA for developing the "resilient wheel". They consisted of a spun aluminum hub and a 32-inch (81 cm) diameter, 9-inch (23 cm) wide tire made of zinc-coated woven 0.033-inch (0.84 mm) diameter steel strands attached to the rim. Titanium chevrons covered 50% of the contact area to provide traction. Inside the tire was a 25. Maneuve...
