Tire question

...and blaming Mary.

But Mary and the mechanic know who's really responsible :-)

Margy and our mechanic blame me for anythign that breaks. And I haven't
broken any rudder pedals since I bought 4 spares at the aeromart at Oskosh
a decade ago.

"No matter what goes wrong, someone
always claims I was responsible."


Someone questioned earlier if you were always landing on one wheel vs. the
other. Quite possible. At my home airport, probably 90% of the time the
landing is with a quartering left front crosswind. So the landing is
almost ALWAYS left main first. Could be something similar, so "familiar"
that you don't even think about it.

Then again, could be that one wheel just needs alignment. G

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...)

One can be, but the effect would be to produce either excessive or insufficient
toe-in with a tendency for the aircraft to move a little sideways on the ground.
If bad enough, it will require noticeable rudder input. It would not produce
different wear patterns on the mains. Bending one axle either up or down *would*
produce an odd wear pattern on only that one wheel, but only a tendency for the
wear to be on either the inside or outside tread.

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.

Yes. You can buy shims to adjust toe-in and camber.
