Hey Ron! Your typical 205/85-14.5 tire has an outer diameter of 28.2". For a tire with a similar diameter that will fit your 15" x 6" rim you can use the Karrier ST225/75R15 Radial Trailer Tire # AM10303. This has an outer diameter of 28.4".

I think they are a great trailer tires. I would add a set of tire preasure sensors to go along . Also calculate your load weight loaded and make sure your not right on edge I calculate more tire than needed so your not heating tire up

I have 2 trailers and have tried several different brands of tires. Most of them only last 2 years. I only buy Karrier tires for my trailers now. They last longer and ride very smooth.
