The 215/60-8 tires like # AM1HP26 should have a diameter of 18.2 inches and a width of 8.5 inches so they should be the same width and yet slightly smaller diameter. If you just go by the definitions these tires should be really similar with the 18.5/8.5-8.

There is some variance in sizes depending on manufacturer as some take more liberties than others for instance the Kenda 215/60-8 Bias Trailer Tire with 8" White Wheel - 5 on 4-1/2 - Load Range D # AM3H323 has an outer diameter of 18.1 inches and a width of 8.9 inches. We do print the actual diameter and width of each tire for this reason. All of our current tires are Kenda and they are 8.9 inches wide which will account for the width being an issue for you.
