I think you are probably right. I think load capacity is only related to the amount of air in the tire, and when you don't increase the physical size of the tire, you can only get more air if you can increase the pressure. And you only want to do that if you have more plies on your tire that can withstand that pressure.

Tirerack seems to say the same thing. They say:

"All tires with equivalent physical dimensions carry equivalent loads (until they reach their maximum load pressure)."

see http://www.tirerack.com/tires/tirete...jsp?techid=195

But in the case of an LRE vs. LRD tire, for example, while their load capacities may be the same at, say 65 psi, I would think the LRE tire would be able to better withstand aggrevating factors like heat and bumps. Or maybe that's wishful thinking. But I can't seem to recall anyone have an LRE tire blowout here.....

Concur. And there's certainly no valid argument on purchase price difference. D's and E's are about the same. I just noticed that you're running the same brand (Carlisle) that I have. I've been happy with those so far.

I just completed the 15" upgrade doing the lift and changing to Maxxis 225 75R 15 Load Range E. I'll be running them at 70 psi and the first spin that I took with them, I could not notice any difference in "bounce". Here is a link to the Maxxis Tire Inflation chart. http://www.maxxis.com/trailer/traile...nflation-chart
According to this, the load rating at 70 psi is 2620#'s which is about what the wheel rating is, 2600#'s. Also it's over the trailers rating which gives me a warm fuzzy.

Checking out the WDH after installation, I didn't have to do anything to the adjustment there. Everything seemed right on the money.
I did have to add about a 3/4" drop to the spare tire carrier but that was no big deal.
