As for the rougher ride, you don't have to inflate a tire to its max. But, the E's may have a stiffer sidewall.

Not inflating a trailer tire to near its maximum will result in more sidewall flexing. More flexing means more heat which will lead to faster wear or possibly failure.

But they're talking about running it at well under its load rating, which means less sidewall flexing. It's very common to run tires at less than their maximum pressure rating. Some tire manufacturers put out charts with suggested pressure based on the load. The max pressure is only correct for the max load.

Running near the max pressure, but with a load significantly less than max, is what will result in greater wear.
