    Had huge probs for last 5 years with tandem trailer.
    I had issue's with turning in culdesac's with wheels bending due to weight.
    Tyres would tear and wear, even leaving black marks on road.
    One hub actually broke off causing rear wheel to drive over it.

    Changed axles, hubs and large wheels 6 stud higher profile.

    The work load was on limit so now feel safer increasing its load capacity.

    Shall find out in morning and tune electric brakes in.

    Hope pic works

    You really need to upgrade to either a heavier trailer or better rim/axles, my old trailer was the same, even though the axles were rated for 12,000 lbs, as soon as I turned, I was almost tearing them off the leaf springs. Now my current trailer is overkill, 20,000 lbs and tandem dually wheels.
    Those look like twin 3500 lb axles? You might want to consider going to twin 6,000's or even a single 7,000 lb axle for insane tight radius turns. At least with either combo's you will get better rims and lower profile tires, but after all the costs are in, a new trailer might just be better off.

    Overloaded? I'm sure there's maybe close to 7,000 lbs there with the trailer and everything, but I wouldn't call it overloaded. I pull a 20' tandem axle with the same size axles and it gets around just fine and I'd bet I have more weight on mine than that and I turn in culdesacs frequently. Never had a bent rim, though when you turn it appears so because one tire is flexed in and the other is flexed out.

    If you are having problems then maybe upgrading to new larger axles is the way to go. Pretty large expense, and at least in the pic you posted, your trailer looks pretty new.

    Trailer is 5-6 year old, trailer has just had full change.
    Rim's are heavy duty as well as hubs, axels etc.
    Larger profile tyes helps also let the rubber twist instead of the hubs.
    Shore tandem wheels bend a little but my earlier prob was scary.
    Waiting to get new load weight etc.
    Today in culdesac's the tandem wheels didnt even bend loaded so ver y happy.
    Elec-brakes tunned in through the day learning the adjustments.
    All up truck trailer is 43'feet long.
    I dont know but feel hub's were y issue before.

    Yeah I think you need to either relieve some of that load or get a heavier trailer.

    Look, the first thing that goes when overloaded is the tires.
    Upgrade that and the axle and suspension comes next.
    See how do I know this?

    But once we get to axle and suspension you're upgrading that?
    This could spell trouble, the frame is the only thing left, there are but
    so many components that make up the trailer and once we push one
    component after the other beyond their limits we reach the end of the
    road... And when we get into the frame and we overload it that can and
    will end up bending the frame, permanently.

    Even on trailers without beefed up tires / axles a frame can bend, but usually we know better than to go that far.
    And how I know this, my trailer's frame is very slightly bent :p
    By very slightly bent I mean your everyday look doesn't see it, but either a close inspection or I can.

    Now a very slightly bent frame isn't a big deal, but if it bends
    any worse the entire trailer becomes useless, the only ones who
    could fix this are specialty automotive frame shops and most folks
    don't fix a bent trailer frame due to the cost.

    Even if you are close to having the max. load on the axles, you need to remember the weight of the trailer, so if you have 7000 lbs max. capacity on the axles, and you only have 6000 lbs of load, the trailer still weighs 2000 lbs, now you are 1000 lbs over weight, and the recommended weight load of the rims, tires and axles, best thing to do is go over kill like I did.
