For the last few years, I've had a tire pressure monitoring system on
the tow vehicle that includes the trailer tires, hoping to avoid the
tire failure in the first place. Looking the tires every time I gas up
helps, too. If the tread is beginning to separate, this will likely find
it before the tire pressure is affected.

In some cases, perhaps not all, I think the tread separates completely
and the tire continues to run inflated until the carcass fails. I
think that's what happened when my Cobra tire failed. There was no
damage as would have been caused by a flailing tread and only about 3
inches of the rear of the fender cleanly rubbed away along with half
the mud flap. I had a flailing tread failure on the Minden trailer and
it bent the hell out of the steel fender and the rear support bar.
