The way I always explain it is this:
Your tandems (trailer wheels) are stationary, move the load towards the smaller of the 2 weights. Example, you have 32425 on your drive axle, and 33967 on your tandems. With your trailer brakes set & pins released, pull the truck forward to move weight forward.
On average, most reefer trailers when you are moving your tandems, you move between 300 - 500 lbs per hole. So with this example, you would want to move your load forward (tandems back) 2 -3 holes to balance the load between drives & tandems. But also as was pointed out, you have to keep bridge laws in mind for the states you are traveling into/through.

A set of axles spaced close together, legally defined as more than 40 and less than 96 inches apart by the USDOT. Drivers tend to refer to the tandem axles on their trailer as just "tandems". You might hear a driver say, "I'm 400 pounds overweight on my tandems", referring to his trailer tandems, not his tractor tandems. Tractor tandems are generally just referred to as "drives" which is short for "drive axles".

A refrigerated trailer.
Also, I forgot to mention, you are only needing to move 1/2 the weight to balance the load.
As in the example I gave, you only need to move 775 lbs, not the full 1550.

Thanks Ernie S. I will try this and apply it to my daily job. I appreciate your help and advice.

Easiest way. Imagine a board, with a weight on either end. Fulcrum point in the middle. What happens when you slide the Fulcrum right, where does the weight go. Now slide it left, now where is the weight?
Now stick 18 wheels under the board and a steering wheel and you got a truck!
