You know, I was wondering about that. Can a fixed landing gear be "cocked"
to one side or the other? That would wear a tire out in no time. (Although
it wouldn't explain flat-spotting...)

Cherokee main gear *can* be aligned. It's described in the maintenance
manual. You adjust it with shims that look like really big, but thin,
washers. They go in the upper and lower joints of the trailing links. By
shimming on one side of the link or the other, you remove any slop, and
tend to cock the axle in one way or the other. I've shimmed mine, but
we kinda' eyeballed which side the shim needed to go. It worked out OK.

Cherokee missalignments tend to show themselves in the common "inner"
tread wear. I "fight" that problem by unmounting and remounting my tires
backwards, after the start wearing the inner surface.

The type of flat spotting that you describe seems more likely to be a
brake problem.
