Hi Trying to understand a recent comment I heard that adjusting the tyre pressures on a tandem axle config will affect the lowball weight is this fact or fiction --- thanks for advice and comments...
I would suspect that it relies on a few variables ,whether it's rocker or slipper springs ,height of tow ball in relation to trailer being level , but I doubt that pressures have anything to do with it at all.
Dennis, amend that to load sharing or non load sharing suspension (most independent suspension is also non load sharing.)
This is a bit of a long bow exercise. I don't think that many owners would vary the tyre pressures between the front axle and the rear axle. That is about the only way you will change the tyre pressure will alter the ball weight.
You will get more change in ball weight by raising or lowering the ball height with non load sharing suspension. If you lower the ball the front axle will take more than half the vans weight and the ball weight will reduce a bit. If you raise the ball height then the opposite will occur.

Agree with Peter and the difference would likely be of very little effect. Best way is to load correctly and if ball weight is excessive you have overloaded.

Thanks guys much appreciated you have come up with almost identical thought process and reasoning that I did so as mythbusters say its highly unlikely to make that much of a difference.
