The benefit of the E tire comes at those higher pressures.
My 11200 lb 5er came with ST225/75-15 D at 2540 lb capacity on 5200 lb axles. Actual weight on each wheel was around 2400-2450 lbs.
I don't use ST tires in those load ranges so I went with LT215/85-16 E at 2680 lb capacity. I keep them pumped to max pressures 24/7. I'm on the second set at 48k miles....first set ran 55k+ miles.
Interesting that you chose a LT size that only increased your carrying capacity 140# more than the stock "D"s. My 5er has LT235/85-16 E's at 3,042# each. I carry about 9,500# on the 5er axles so run about 70 psi in the LT's.
