As long as the combined load capacity of the tires still meet or exceed the loaded weight of your trailer, there is no particular reason you couldn't change to a smaller 205/75-15 tire like the Kenda Loadstar # AM1ST92 that you were looking at. Just keep in mind that the smaller size will also drop the ground clearance on the trailer just a bit. The current 235/75-15 size tires you have on the trailer feature an overall diameter/height of 28.9 inches, while the 205/75-15 tire will have an overall diameter/height of 27.1 inches. Only half of this difference (0.9 inch) will actually affect the ground clearance. This size tire will fit 15 inch wheels that have a 5 inch, 5-1/2 inch, 6 inch, or 6-1/2 inch width. You will just want to make sure your existing wheels are compatible.

The Kenda Loadstar # AM1ST92 has a maximum load of 1,820 pounds at 50 psi and an excellent speed rating of 81 mph. I have attached a short video demonstration on this particular tire that you can also check out.

The two sizes you mentioned are pretty similar and fit many of the same 15 inch wheels. The 205/75-15 fits rim widths of 5 inch to 6-1/2 inch whereas the 225/75-15 fits widths that are 5 inch to 6 inch. The 205 is 27.1 inches tall and the 225 is 28.4…

The 5.30-12 tires, being wider, are going to make more contact with the road. This means that the noise, and heat build up will be higher than a 4.80-12 tire but the rolling resistance will actually be less because the tire is larger diameter. The…

Since both a ST145/R12 size tire, like the Kenda Karrier S-Trail #AM10130, and a 5.30-12 size tire, like the Kenda K353 #AM10068, fit a 12 inch wheel, a ST145/R12 size tire can replace a 5.30-12 size tire. Keep in mind that these tires do have…
