Expert Reply:

A 205/75R15 tire will be quite a bit larger than a 4.80/4.00-8 size and will also mount onto a larger wheel. These two sizes will not be interchangeable on your trailer.

As a reference, the 205/75R15 tire has an overall diameter of 27.1 inches and will mount to a 15 inch wheel. The smaller 4.80/4.00-8 tire has an overall diameter of 16.1 inches and mounts to an 8 inch wheel.

We do have a large selection of trailer wheels and tires in both of these sizes available. I have attached a couple of links that will take you to our available selection that you can look through. For a replacement 4.80/4.00-8 tire, I recommend looking at the Kenda K371 Bias Tire # AM10004. This is a Load Range C tire that has a maximum load of 745 pounds at 90 psi and a 6 ply rating. For a ST205/75R15 tire, the Provider Radial Trailer Tire # TR20515D is an excellent choice. This radial tire has a maximum load of 2,150 pounds at 65 psi and an excellent maximum speed rating of 81 mph.

I have attached short video demonstrations for both of these tires that you can check out.
