Tire Load Range

I don't need to know the plys at all, I just have to look on the max load on the side of the tire and it says 6,175 lbs and the correct tires on the back of the same brand and model in H say 7,160 lbs. It's really pretty simple.

That means nothing. What carry capacity does your motorhome specify? If the specifications calls for a specific carry capacity, so long as the tire meets that carry capacity, the correct tire was installed. now if you want excess capacity above what the manufacture calls for, that is a whole different thing. My small RV calls for a load "index" of 115 but my personal preference is to go 121. If I don't tell the tire dealer I want the excess capacity, they most likely will specify tires with the 115. What is on the tire itself has nothing to do with what your motorhome requires. Now if you asked specifically to use a certain carry capacity or the motorhome specifications called for a certain carry capacity, they should have followed your instructions or the manufacturer specifications. But max carry capacity written on a tire in no way indicates what is required.
