Using a Bias ST215/75D14, like part # AM1ST90, and Radial ST215/75R14, like part # AM10229, tire at the same time on your trailer should only be done if there were an emergency. Since there is a difference in how those types of tires run, wear, and cool, you could end up having an uneven ride or tire failure.

The ideal setup is to have all bias tires or all radial tires. That is the best way to stay safe and know that you will get the most life out of each tire.
