Does 8.25-15 Tire Size Have Same Diameter as 225/75-15

Question:

I have read that the 225/75R15 tires are similar but I want to know if they would be exact replacement except the 1/2 wider.

The 8.25-15 tire would have an 8-1/4 inch width and a diameter at 28-1/2 inches whereas a 225/75-15 like the part # AM10303 has a diameter of 28.4 inches so they are very close. The two would interchange easily as long as the trailer was planning on swapping to all the same size but would not work as just a single replacement long term.
