Front axle weight?

The other day in Tennessee I got put oos at the scale with 15K on the deck .I was 13600 on my steers the cop was a prick. He said slide your 5th wheel, move your load, or buy new load range H tires or tow it off my road...my 5th wheel is all the way back,I had 23 pallets evenly spaced and tarped on the trailer, ofcourse my tanks were full of fuel ..so I ended up calling the Goodyear tire center 3 miles away I dropped my trailer and he wouldn't let me go 3 miles so the tire shop cane to me. I removed 2 3month old Bridgestone tires and put on 2 Goodyear load range H tires I put it back on the scale and was told dont bring that truck back here without it being leagle.....that being said any sushestions?

Getting back to the OP question, with 13,600 on the steering axle bobtail...
Either invest in a set of wider rims and run 315Rxx/22.5 steering tires, or move the fuel tanks rearward.
Personally, I would be diligent about not crossing scales with fuel tanks filled to the lids to "mask" the issue and keep enforcement off your back. However, BE DILIGENT about making sure you continue to run adequate tires! I know this is saying to run in excess of the axle rating, however the axles are highly over-engineered,so being 13,200 only while bobtailing which doesn't account for a significant percentage of time, is unlikely to be an issue.
If this isn't a realistic possibility in your world, I would consider shifting the tanks rearward.
Then i would look into shifting the 5th wheel slider track further back to allow the 5th to get behind center of the drive axles to pull weigh off the front end. I don't like this option! Pulling weight off a the front end can cause handling problems in extreme circumstances. An example would be hitting some frost heaves causing front-back rocking coming into a curve with slippery roads. The rocking could lighten the steering load enough to cause a loss of traction, or a large increase in downforce exaggeration traction...either way, not a good set of outcome possibilities...
