Good info...thanks...if I rotate, it'll be as suggested.
When I place mine in storage, it's inside. I have some "astro turf" type material I place on the floor and roll the trailer up on that.
Due to the temp typically dropping near or at times below zero, I tend to fill the tire PSI when I store it for winter to about 68psi each tire. Before I pull it out for the season, I make sure that cold PSI is back to 65.

Hi, 2air. You have six tires, all the same age, same mileage, same pressure, Etc Etc. One tire is wearing faster than the rest and seems to be even. Normally I would rub my hands on the tire in different directions, but here I will have to go by what was stated and what I can see from the pictures. My first guess is that one disc brake is pulling harder than the rest. There is a tool for measureing the actual pressure the caliper puts on the pads; This tool fits in between the pads and or the pistons in place of the rotor. Test all six. Pressure should be the same on all. Next, the friction quality on the pads could be different on that one wheel. Look to see if the coloring and all markings on the pads match. Try swapping the pads on that wheel with the one exactly opposite side. See if that tire starts to wear faster. And my last thought is that the rubber compound on that one tire is different. Maybe if you know someone in car raceing they can test that for you. I don't think a tire shop can test for the hardness of the tire compound. Finally I rule out alignment issues and these are just my opinions.
Too many left turns and scrubbing? Baffling. I say try swapping tires like Robert suggests and see the new tire in the same position does this. If it does, maybe some alignment at just that swingarm is the problem, although it seems to be wearing flat.

It could be that one tire is toed slightly out, but that is difficult to do without changing the camber as well, and you would see feathering on the tread if it was toed in or out. When they take the tire off, maybe you could ask to have somebody look at the inside, see if there are any bumps of bulges that don't belong.
I know tri-axles are kind of hard on tires, but to wear onoly one like that is not good. Do you think you can get Goodyear to warranty it for you? Or not a big enough issue to bother with?

Good question! With our rubber-filled axles I've often wondered what would happen if the rubber in one axle - for whatever reason - was either harder or softer than in the other axles? Say the source for the rubber dowels changed in the middle of the axle manufacturing process to a slightly softer or harder rubber. Just like with tires, quality control issues have a nasty habit of going our of kilter - and oftentimes without being noticed!
If on your previous tires there was no unsual wear at that position. I'd look to that particular tire as the problem.
Hi, if I remember correctly, 2air swapped to disc brakes at or near the same time. That's why I think it could be tire or brake related. If an alignment concern, I would feel side to side feather edgeing on the tire, but I don't have the ability to feel those tires on my computer screen.
ok to update those who offered ideas on this issue...

yep that's the gist of it.

hadn't thought of this. the pads were pulled and all were the same thickness.
additionally i've had disc brakes since the trailer was new and with 40k+ miles on the original pads they are wearing nicely. many are in need of new pads at 10-15k miles.

that was my conclusion also.

the rear tires DO get scrubbed more, but my gut is same # of rights and lefts...

alignment was checked at the factory and reported as normal...
i decided not to bother with the warranty side. too much hassel for 75$...

this was my initial thought (along with axle issues)
factory guys weighed front/rears individually on each side, and they were within 100lbs all around.

i asked them about this. the explanation was, "5 of 6" would need to fatigue for this one to show tire wear...

as noted back in post #13 and 15, i did have one in the first set show signs of uneven wear at 30k, but it was in another position and on the opposite side...

yea the wear was pretty even. my thought was perhaps the centramatics could be masking a balance issue.
....
so after all the above gyrations, the conclusion was the rubber compound was perhaps softer in that tire.
a new tire was mounted and balanced, and all the others were rotated...
i'll report back how this new tire wears....
thanks for all the ideas, guys...
cheers
