Sooo I looked into upgrading to 16" wheels and tires, the problem is that between the factory 225/75-15 tires there is only 2 5/8" between tires. 15" tires are 28.3" OD and 16" 235/85-16 is 31.7" OD, meaning 16" wheels are out of the question.

I have looked into other 15" tires like European van 225/70-15 but cannot find them in "D load" rating. I am aware of the heated ST vs. LT debate as well, but can anyone suggest 15" trailer tires with D load and 65 mph+ speed rating.

I'm not looking to speed, just not run at max speed. Thanks everyone!
As mentioned, Greenball is the only ST tire that I'm aware of that advertises a > 65mph rating unless you get into weighing wheels and adjusting inflation pressure. I've only done per-axle weighings and supposedly for my load can go up to something like 71mph based on the inflation tables and then extra PSI in the tire. We vary our load so much that it would be a hassle, honestly. I'm happy to know that on our average load, I've got some cushion.

I've always been confused with the whole LT tire- I think you would have to change wheels and all to go with them. It was expensive enough replacing my 4 tires with Maxxis, I can't imagine replacing the wheel, too!

I do know that I only have about 1 1/4" or so between my wheels as they came from the factory.

Good luck!

Ependydad, I agree completely with your position of having extra cushion without excessive hassle. Thanks again to everyone, I think I'll be considering Greenball as my final contender.

Trailer rims can be used with LT, P-metric or Euro-metric tires. However, I would guess under most circumstances you would need to purchase new rims since you have to go with larger tires when replacing ST tires. That is probably the only good thing about ST tires, they have a very large load range capacity for their size. (They sure don't hold up on serious off road trails.)
When I went to P-metric tires on my 228, I went from a factory size of 175x80-13 to 215x70-15. Long story, but the trailer was lifted 4+ inches so I could do it.
And, even factoring in the factoring in the 91 percent rule for the P-metric tire into the calculation (and not sure it was actually needed) the tire exceeds the load range of the factory equipped tires by 150 lbs each.
