If you had a matching trailer tire size to what is on the trailer but instead it was a bias ply and the trailer had radials you would be okay to get home in an emergency, but it wouldn't be an ideal solution.

Instead I would recommend you go with a radial in that size like # TR20515D instead on your spare to allow to match the construction perfectly.
