It would probably be best to be able to fabricate lunar transport tires on the moon.
Which metals and other carbon-based materials handle temperatures ranging between -427F and 250F? Which of those materials can be fabricated with on the moon?
All-electric fusion induction welding would probably work on the moon (without filler gases).
