I think you are at the heart of why mfgs put the same tires on all axles and why every owner that has weighed in on this thread recommends the same.
The tires that came off our rig had more than half the tread life on them left. The only reason for changing them was due to age. And they, like most have never been rotated. To rotate the tires on a MH we would have to have them remounted and balanced due to different rims on each axle.
My conclusion is that H rated tires are over kill for the rear of our coach and is likely the case for others that have tag axles. In the future, if cost, comfort, or availability become an issue with replacement tires, I will go with the G rated.
