Best wheel for the job?

[Sobriquet]

I would like to move 324T of miner/refinery around the surface of Minmus. How many Rovemax XL3s will it take to support it? Or should I be using landing gear?

I keep adding XL3s and they break on the runway.

Landing gear, the heavy ones have a impact tolerance of 70m/s (but they do transfer impulses so you can't just drop from on high and expect everything to be cool). For 324T 4 heavy or medium landing gear should be enough.

The surface gravity of Minimus is 0.05g so a 324t would only weigh 16.2 tons (of newtons, NOT MASS)

On big'uns I use XL3's - but I add struts. Helps a lot - I get the impression that the attachment point is weaker than the gear as a whole.

As you say, they break on the runway. Four to six on Minmus should be just fine, as the gravity is much lower.
