Good news, I can help you find a tire for your Sundown Horse Trailer.
The 205/90-15 is a close tire size to the 7.00-15. The closest size to a 7.00x15 tire that we offer would be a 225/75-15. One 225/75-15 tire that could work for you is the Kenda # AM10303, this tire would be slightly shorter and a little wider than your 7.00-15 tire.
Something to keep in mind is that a 7.00-15 tire typically fits 15 x 5-1/2 inch wheel. The ST225/75R15 tire size will fit on 15 inch diameter rims that are 6, 6-1/2, or 7 inches wide. They will not fit on rims narrower than 6 inches. I recommend checking the width of your rims to determine if the new tires will fit. Another thing to note when moving to a different tire size is fender and frame clearance.
A 7.00-15 tire will be about 8 inches wide and have an overall diameter of about 29 inches. The overall diameter of a 225/75-15 tire is about 28 inches and it will be about 9 inches wide. This means the new tires will sit about 1/2 inch closer to the inside of your fender or trailer frame. I recommend measuring the space you have available to make sure a wider tire will fit.
