    I have been driving straight axle trucks for a long time and never did anything with a trailer. My question is with a dual axle trailer and let's just say a single axle tractor if I had something that 20K and put it on the trailer what percentage of the weight is carried by the rear axle. I don't think it's 50/50 but with dual tandems it maybe I do not know

    What kind of trailer? dry van, reefer, etc.
    What load and how it's loaded?
    Heavy coils that are concentrated in 2 separate areas, front, empty space, and back?
    Bring some more info and we'll help you with an estimate.
     
    Gonzo1300 Thanks this.

    I was talking to a Hotshot guy and I'm pretty sure it was a 40 ft little flatbed trailer. He had some long pipes on it that was close to the size of the trailer. I believe the side of the trailer said 26NG. I got confused because he said all the pipe by itself was 19600lbs. It's a 5500 truck and I know the axle is much smaller than the trailer but for that the work just the way I was thinking of it is if they put 20,000 lb on that trailer that means the drive axle is carrying roughly 30% of the weight of the trailer and the load combined is that not correct

    A tandem axle on a 40ft goose neck trailer comes in 10-12-16k weight rating.
    Assuming a 16k per tandem axle and a total of 21k gross,
    the single drive can be loaded with about 4k probably and the rest on the steer axle.
    It's an educated guess, not a scientific white paper.
    Does it answer your question?
     
    Gonzo1300 Thanks this.

    The percentage of weight carried by rear axle depends on where the load is placed in relation to the rear axle

    Must complicate things when you place the load and it just walks away.

    I read something years ago when I first started that said. It’s easier to carry a load than to drag it
    At first you think it makes no sense. It’s all on the trailer but load heavy to the rear and you will feel the difference
    I don’t run hotshot but do load heavier on the drives than trailer axles if I can

    We are thinking about a Hotshot setup for our main customer. For our customers sake and to make it simply better for them we would like a 48 ft trailer so we can get more of their units on there. If we had saved to 16k axle will of course a good trailer and I load a 48 ft load that weighs 20000 lb on that trailer I do not want to put too much on the drive axle
