Ah ...... Mmmmm ...... Not exactly.
I think you are confusing ST tires compared to regular car tires. ST tires carry more load because of the higher inflation pressures. But ST tires come in both bias and radial - at the same load carrying capacity!
To the OP:
Check to see if you have a vehicle tire placard. The tire placard will list the original tire size and the specified pressure for that size.
Since 2008, it's supposed to be on the driver's side front of the trailer. If your trailer is older than that, it could be anywhere, but usually on travel trailers it's behind or near a door - sometimes a cabinet door.
Oh and radials will have better fuel economy - all other things being equal.
