A trailer can be fitted with higher-capacity axles (or hubs, or wheels or tires) to increase the weight capacity safety margin but this does not increase the overall trailer weight rating. Changing a trailer's tires to a higher weight load range is a popular and much easier way to add weight safety margin. In your tire size 235/80-16 we offer radials in either Load Range E or Load Range G. Please refer to the linked page.
The Provider ST235/80R16 Radial Trailer Tire # PRG80235 is rated as Load Range G which means each one can handle 4080-lbs at their rated 110-psi pressure. It is also rated for speed up to 81-mph. If you have Load Range E tires now switching to G-rated tires will allow them to run cooler which usually means a longer lifespan.
If your goal is to be able to load more total weight into the trailer then I would first contact Keystone with your trailer VIN to get their input. If the axles actually were the "weakest link" in the trailer in terms of weight capacity then changing them would give you that benefit of extra safety margin, but only the manufacturer can tell you that.
