In this instance a "dual" application means 2 tires side by side on one end of a single axle- like dually trucks have. Not 2 axles each having a single tire on each end (which is called tandem axles).
That said, the tires are still likely close to maximum capacity. I know my tires didn't have enough capacity to fully support the axles. Never caused issues, but I did do upgrades to make me more comfortable.
Also- not sure where you are, but various places around the country have outfits who will do individual wheel weights. It can be very enlightening.
