Just create your own class derived from the UWheeledVehicleMovementComponent class and utilize the PhysX tank movement (you can find their API and samples online). You would then include PxVehicleDriveTank.h as well. This is what we did. Let me know if this helps or if I can provide more information.
#if WITH_VEHICLE
#include "PhysXIncludes.h"
#include "PxVehicleDriveTank.h"
#endif // WITH_VEHICLE
