New trailer has odd tire wear?

[Chinookie]

The story: I bought a new ezloader torsion bar dual axle trailer four months ago and paid a company to haul my Grady from the east coast to Seattle. Two weeks ago my neighbor noticed something I hadn’t, both of the tires on the right side are bald on the outside edges. I called ezloader warranty and they had me take it to a local dealer where it is now being evaluated for possible warranty coverage. While I was talking to that local dealer, he said it could be a number of things. While looking it over he did notice water was in the hubs. I said that’s impossible because it hasn’t been in the water and he said that he has seen this before, the bearings get hot and open up the seal and it sucks moisture from the air in. While talking to him further, he said that the driver that I paid to tow the boat over might’ve jumped a curb. If that was the case, wouldn’t that produce inside tire wear from bending the axles upwards?

I am posting this here in case anyone knows what might be causing this tire wear problem on a trailer with only a few thousand miles on it. Thanks!

By the way, the EZloader warranty contact has been very responsive and I don't have reason to think this wont be resolved under warranty. I am just trying to figure this mystery out in case the local dealer cannot.

Assembled/welded wrong leading to a funky angle of the axle stub. It's not a "common" thing, but it does happen.

I tow my 268 Islander to Florida Keys and back every winter since 2008. About 8,000 lbs including the trailer. About 3,000 miles - similar to your one-way trip. First few years were with an old 3-axel trailer. Last 11 years were with a new Sea Lion S-28T-8200BB 2-axel trailer. The new trailer has never been in the water - I pay the marina to pull it off and put back on. I have had wear problems with the tires similar to yours. Wearing tires out an a round trip. Replaced tires individually and as a set a few times. Had trailer alignment and bearings gone over by a professional trailer shop two years ago.

What load rating on the tires? Max PSI? How much air was in them when it got to you?

Were the wheel bearing loose (like you could wobble the wheel)? I'm not sure I buy bearing hubs making water!

What I learned and did along the way was:
Upgraded from bias ply tires to radials.
Upgraded from C rated to D rated to E rated tires (80psi cold).
Switched two tires to E rated Continental. Has been using LoadStar E-rated. Trailer shop said they are better tires.
Always run the tires at or near max tire psi - I'm doing 75psi now.
I re-packed wheel bearing 3 years ago. Trailer shop said wheels were wobbling a little - bearing not tight enough - re-kitted all 4 wheel bearings.

Last two years have been perfect.

Usually, excessive wear on both outer edges is a symptom of low tire pressure.
