Hey James, based on what you listed having on your Harbor Freight trailer the Kenda Karrier S-Trail ST145/R12 # AM35351DX would work great as its the same size wheel and bolt pattern and the tire is a radial like you are wanting. The Load Range of the tire is D which is higher but that just means it has a higher weight capacity at 1,220 lb at 65 psi.
Are you wanting a radial for improved speed rating or handling?
