    If you offset the flat spots? I've done this a bunch for past customers, but never saw any wear out.

    My son changed 8 for one of his customers. 2YO casing XDN2's. Tread depth on all the tires is 23-24/32"'s, and the deepest flat spot has a tread depth of 19/32".

    Has anybody gotten significant mileage out of a tire under these circumstances? I can get em for a little over 100$ a tire

    I’ve put fronts that rivered and basically had flat spots starting and moved them back.

    I run max air pressure and they wore fine….

    I’d probably try it

    Yeah, think I'm gonna have to at that price. If my current XDN2's last till end of summer, I'll have 360-370k on them. They're at 7/32" now.

    If I get 100k out of them I'm money ahead

    For $800 I’d try them and see what happens.

    My experience is the tires only as good as it’s flat spot. That’s on a Trailer. Doesn’t matter 1 or 2. Doesn’t matter if mounted opposite. They wear out at the flat spot, or river wear, cupping gets worse. The exception is on drives. Just the opposite. I’ve ran old steers with a worn outer edge, river wear, cupped. Doesn’t matter. They’ll run forever wearing only the good tread. Outer edge doesn’t get any worse. I can only imagine it’s because of torque vs. free spinning Trailer tires? Maybe bad shocks on Trailer? No idea. Whatever the reason. I’ve seen it time and time again. I’ve only bought 12 new drives since 2009. 1.7 mil miles. Lol. Always new steer’s every 130-150k. Right one wears on outside edge. I’ve sometimes waited too long. Put old steers on drive, side by side worn edge inside of inner. Tire lasts just as long as the evenly worn steer. Usually another 130-150k till I buy another set of steers.

    You'll never wear the tire out to be even with the flat. It'll always be the low point.

    Technically they would be considered unroadworthy, however not so bad if you used them on the rear of the trailer, I would never run them on the drives, and definitely a no for the steers. But you can still get a lot of life out of them.

    As long as they measure 2/32 and don’t have cuts they are legal.

    At least here in the new 3rd world

    Years ago didn’t some people spin balance tires and use a chisel or some sort of knife to cut high spots .. As long as they don’t thump I’d run them it’s a relatively soft sidewall so it might not be bad.
