Going from a 205 to. 225 tire
I was fixing to order some new load range D tires the other day to replace the cheap load range C that came on the trailer. I just happened to stop by storage and I am glad I did before ordering tires...

My concern was that the tire was going to require 80 psi for a "D" rating. But the tire spec said "C" @ 50 psi and "D" @ 65 psi.
As far as the rim is concerned, I as more concerned about the valve but they use the same valve for both applications. I suspect it is the same with the rim.
Correct, load range C is 50 psi, LR D is 65 psi, and LR E is 80psi. I went from LR C to LR D and changed the valve stems to the "snap in valves for high pressure". Also had the wheels/tires balanced.
Here is a little reading on valve stems:
