plastic or metal fenders on the trailer?

I don't know what goes on in detail when a tread begins to separate, but I
hope it raises the pressure enough to trigger the high alarm, or loses
enough to trigger the low alarm, before it fails catastrophically.

There are two types of tread separation; one caused by the tread not having
a good bond to the cord, and one where the layers of the cord separate
taking the tread with it. Most old tires that are not retreads are the
second type, and retreads failing usually are the first type.

If the body of the tire stays whole, the pressure will not change, sorry to
say.
