E vs. D rated trailer tires
We are moving back to WI after 4 years of living in Miami and I'm making my list of items to address since my unit is 5 years old. One of those is tires. I still have the stock 'Trailer King" D rate...

I see no one has mentioned that a Load Range E has the same load carrying capacity as a Load Range D when inflated to the same pressure. At the LR D pressure, a LR E performs the same - ride, sway, etc.
So you can buy a LR E and use it in place of a LR D.
Endurance Load Chart
I have 8400lbs across 4 tires. So according to the chart I should air them to 50psi. Even at 55psi they looked too low and would have too much sidewall flex. 68psi just looks and feels right to me. YMMV
My Endurance on my Boat Trailer "LOOK" low but the proof is in the pudding they are right on at 50psi as the tread is perfectly even at 20,000 miles.
