I just noticed that my 1 1/2 yr. old boat trailer (galvanized bass tracker
jet boat trailer) is showing no tread wear on the port side, yet the tire on
the starboard side is horribly worn, especially along the outside edge. I
estimate it has 1,500 miles on it at most.

At first glance it does not look like I can adjust the axle.


The 3 most likely culprits are a cocked spindle, under-inflation, and
unbalanced load.

Low end trailers are notorious for having misaligned spindles. But not
as notorious as trailer ties aree for being under inflated. I can't ever
recall gettin ga new boat trailer tha didn't have its tires under
inflated. And if they're unvenly underinflated, the one with the lower
pressure will absorb the bulk of the wear -- usually evident as wear on
both edges with noticeable cupping on one edge or the other.
