Center of one trailer tire wearing

[Tuckerbug]

Guys and gals,
I have a NP 381 DLQS with Moryde independent suspension. I replaced the wheels with Boar Wheel 19.5” and run Michelin tires. Same as my F450.

Great setup but today when doing my wheel bearing maintenance I noticed the rear left tire is wearing down the center. My first thought is over inflation but I have a TPMS system and watch the air pressure very closely. All tires stay within 1 or 2 lbs when rolling.
Any ideas how one tire can wear in the center?

That's really strange.

Just guessing here. You bought upgraded tires for the trailer and you are running the Max pressure listed on the sidewall of the tire.

Max cold pressure is 110psi, I run 90psi cold in all 4 trailer tires. It is only one tire that is wearing like this.

Then I agree with Taft, really strange. Try to get replaced under warranty.

That's not over-inflation wear I've seen a lot of tires in my day and that's a first. I'd contact the mfr.
