I agree, static load is nothing compared to dynamic load when the vehicle is in motion. Driving through some of those dry creek dips in the Flinders Ranges at speed for example, could possibly triple (guesstimating) the load of the spare wheel on the door, and those outback corrugations will fatigue anything over time.
