As mentioned in one post reply, the failures happen in seemingly random 
locations.  Except for the last two. The drivers side middle axle failed 
and I never even knew it, lol. It exploded and sen rubber parts 
everywhere. Then the trailing wheel was found to be bad also when I was 
changing the middle one. It hand not failed but the tread was separating 
from the sidewall at the shoulder. Others have occurred on the P side 
but always singly.  Common factor seems to be the manner of failure and 
that is tread separation at the shoulder of the tire.

When I load the trailer I try and load it somewhat symmetrically.  Motor 
of the car is between the first two axles, etc...
