HELP...Strange Tire Wear

Forest River RR19 toy hauler. Very strange wear on just one tire.

These tires all have about 14,000 miles on them.

Three of them look perfect but one tire has strange wear. this is rear, drivers side. Trailer has not had a "toy" in it during this 14K miles. So not overloaded.

I jacked up trailer to check bearings and all are good. All bearings were replaced 3K miles ago. everything is good. No loose lug nuts, no loose bearings. Breaks are not rubbing.

Why it is strange is that the wear is only in two spots. It is not consistant around the whole tire.

Anyone ever seen anything like this? I'm going to install spare and monitor as I have 1200 miles to get home.

    We can't tell from here, but it could be bent axle or a bad tire. One sure thing is the total neglect of the suspension and that may have caused spring bushing wear.

    Looks like a bent (or poorly made) axle. The wheels/tires should be straight in line, but in the picture it looks like that tire is pointing outward compared to the other wheel/tire. Take a straight board, and see how the wheels/tires are aligned on both sides. Perfect would be the board contacts the sidewalls, front and back, on both tires.

    The pictures above appear to show maintenance neglect on the suspension. Those zerks on the spring shackles are rusted and don't look like they have ever seen grease. You also appear to have a tire out of alignment, causing wear and increased tire temps. Hard to say what the alignment issue is, but a good alignment shop that handles trailers could identify it.

    According to my tpms, the wheel runs about 4-7 degrees hotter than the others. Given that the bearing and spindle are ok, not sure why that would be.

    It sure seems obvious the wheel is out of plumb. Who could fix such a thing..or would it be ok to just live with it?

    Bearing are less than 5000 miles. No slop and wheel spins fine with no noise.
    Yes, insde of tire is worn.
    I put a level on wheel and it is spot on.

    Three things, you two and axle(s) out of alignment. That side member looks rough too.

    It looks like the tire might be cambered (tilted) inward causing wear on the inside part of the tread.

    Is that showing the inside rib wearing out? I have the same thing on mine.
