Expert Reply:

Due to their differing ride characteristics and construction, bias-ply and radial tires should NOT be mixed, unless you're talking about a short term-short distance situation. Bias-ply tires have sidewalls that are thicker and less flexible, so mixing the tires could have an adverse effect of the stability and handling of your trailer.

I'd highly recommend going either with all bias-ply or all radials. Radials would provide a smoother ride and shed heat better when under load. Since excessive heat is the number one enemy of trailer tires, a tire that does a better job of shedding heat will last longer. Part # AM10245 is a ST205/75R15 Load Range D Radial tire that would be an excellent choice.
