Axle weights

I know we have some truckers here and other smart guys...'splain this to me please.

When I bought the Bird, I weighed it quickly on the way home with about 3/4 fuel and half water.

All USA numbers btw to make things easier :D

I can't recall the exact numbers, but they were around:

front 14300
drive 16700
tag 11000.

Struck me as a little odd....figured the front should be lighter, drive heavier and tag lighter.

Fast forward to now.

Axles and GVW actually add up on this unit .

GAWR
Front 14400
Drive 23000
Tag 10000
GVWR 47400.

An adjustable regulator was installed for the tag bags.

It was factory set at 60 psi.

We set it at 50 psi when I left the shop.

Fuel is now full, as is propane and water...so yes, I will be adding more of my stuff....but this was a way to start.

The front weights following are with my fat ass in the seat....so 230# of variation.

50 psi

front 14146
drive 18062
tag 12232

total 44440

40 psi

front 13772
drive 20548
tag 9900

total 44220

34 psi

front 13486
drive 21472
tag 8866

total 43824

Now I get that the totals are going to vary a little as the bags could be loaded up etc.

But what really threw me for a loop was when I put both rear axles on the scale and got

29106...seems low.
So adding up the front at 13486 gives me a total weight of 42600.

So now the numbers are out for totals of almost 1800#

Thoughts?

Am I missing something obvious?

I actually found and read that when I was digging into this....hehehe.

Scale was a DOT scale, FWIW.

Misread would be odd as I was getting out each time to read and write the numbers. Anything is possible though.

Will be going back next week when unit is fully loaded and trailer on.

The couple of hundred pounds or even 500 I have no problem with....it was the final reading that bothered me.

possible miss read (operator error + odd scale rounding)? axle changing just enough to have the scale round up on the power and tag and down on the steer?

Interesting read. Our county dump weighs all trucks in and out just to establish volume received. The majority of trucks are semis hauling large dumpsters, so they are calibrated for heavier weights.

I took my ATV trailer out two different times to get a weight for titling purposes. The first weight(trailer only) was 1280 lbs. The second weight a week later(trailer only) was 1450 lbs.

46100 total...trailer was just under 4000# so total of around 50,000#....I told Frank nearly 52k#...my math was off :D
