    I’ve been reading a bunch on this subject but it’s just confusing me even more.

    So I understand that tire weight rating is listed as single of dually configuration now what I don’t understand is if you add the total amount of lbs per tire on an axle to get the total load allowed?

    So I have a tandem dually trailer so 4 wheels per axle, 8 in total. Each tire reads about 3k in dual configuration, does this mean both axles hold a total of 24k?
    This is from a tire perspective I know my axles hold 10k each.

    You can't overload any component, your trailer, your truck, your license, the road/law. So even if your accumulated tire ratings allow 24k and your dual axles are rated to 2 X 10k, you are limited to 20k, not 24k, on that pair of axles. No?

    That’s the reason why I asked this specifically from a tire POV. I understand my limits, just trying to understand if tire ratings were the sum of all tires.

    Yes you add your tire ratings.
    Your 4 tires on a 15000 pound rated axle could carry 12000 pounds.
    On the 10000 pound rated axle they are limited to 10000 pounds.

    Add the dual weight rating not the single

    Perfect, I know axle is usually the limiting factor on load capacity.

    It could be the tires or the axle itself depending on the specs. Usually they are pretty closely matched by the people who designed it. The trailer's GVWR will be listed somewhere on the VIN placard which would give you a clue. If it's 20,000 you've probably got 2 10k axles. 24,000, 2 12k's.
