The DOT minimum space between the rear dually tires is 1/2″ (1.27cm). safe at maximum load capacity to prevent small debris from getting lodged between the rear tires which could result in wear and punctures.
Depending on the tire size - spacers between the duals, or on the hub could be necessary to give more clearance.
