If a radial is desired  it’s a ST145R12 which only slightly increase the outer diameter from the original 20.7 up to 21.3 - I thought the same about the 13” bolt pattern but I read otherwise at e trailer. I also called. They confirmed and explained that it has to do with the rim surface area. Not a big deal. My bearings and races are starting to fell a little rough anyway. At the boat ramp today I checked out the trailer parked next to us which had ST175/80R13’s. They would look huge on this trailer. I might have go with the biased 5.3x12 tire as you did. Gives almost a 1/2” extra ground clearance and is a nice looking tire.</blockquote>
