These Euro C tires are mandatory on the Ram Promaster as a standard LT doesn't have the weight rating necessary.
Is that because the Ram Promaster chassis isn't available in a dually rear tire version?
FWIW: As for rear duallies on the rear of a motorhome, I'm all for them in the rear of a cutaway van based Class C motorhome because of the safety they provide by offering a form of "tire redundancy".
For example, once we had one rear tire of a dually set go flat in our Class C motorhome. I was able to keep going very slowly for around 5 miles with only one good tire on the one side in the rear in order to reach both a safe place to pull off, plus pull right into a tire repair facility. Granted, the one good LT tire (carrying 80 lbs. of pressure) was drastically overloaded while doing this, but at least I was able to keep going slowly. That temporarily overloaded Michelin LT tire went on for another 4-5 years providing good service.
For a heavily loaded van/motorhome with only singles in the rear when going at highway speeds, a flat in the rear could result in a very dangerous situation.
