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...

It was a pease of mind for me. One less thing to worry about.
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

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.
