What I would REALLY PREFER on my 11,800 lb. (~fully loaded) 24 ft. Class C are Mud/Snow tires that are so over-spec'd for my MH such that if I blow a rear tire in the dually set - I can drive aways without changing it in situations where it blows and it is inconvenient or unsafe to stop and change it!!
i.e. I had an outside dually Michelin M/S LT LRE blow once years ago on a hard surface 4-lane road with light traffic. I was only a few miles from a small town, so I slowed down to ~10 MPH and drove all the way into the town and had a gas station attendant change it. Of course the other Michelin tire within the dually set was drastically overloaded while I traveled on it. That tire went on as if it had never been overloaded and provided several more years of service.
In other words - another parameter to shoot for in choosing tires for the rear of a rear-dually Class C is ... "can 3 tires in the rear (when one is flat) safely carry you along for aways at low speed until it can be changed?" This is what I call having a "redundancy" tire arrangement in the rear of a dually chassis - and it takes very rugged tires back there that have a generous-as-possible weight carrying margin over what they normally carry day-in and day-out.
P.S. I keep 80 lbs. of pressure in the rear tires all the time. I've compensated for the previously stiff ride in the rear by installing variable rate shocks in the rear that function as "no shocks" on highway cracks and as "heavy duty" shocks on roadway curves and in side-winds.
So basically your old tire did exactly what you “wish” for.
You could always go with 19.5s. But at almost 6klbs load per side it’ll still be overloaded a bunch.
