bias ply or radial

[regcab02HD]

I'm looking at the Super Swamper trXus tires which are radials and the Super Swamper LTB which are bias ply.  

I was wondering which one will last longer and which one will handle a heavier load.

Depends upon the load raring of the tire on the sidewall. Also tells how many pounds tire will support.

 

My thoughts, radial would be the better tire, less heat generated, smoother rolling, meaning smoother ride over rough road. But then, Super Swampers, who really cares? Kind of a mute point.
