Scale weight

Yes, it depends on where your 5th wheel is setting. The previous truck I was running I typically ran at 13,100 on the steers. Just make sure your axle/tires are made for it.

 

The way u pop your brakes have a big effect on scale readings. I always stop then let of the pedal then pop them

 

yes. your trailer is picking up on your fifth wheel. this in turn pushes down on the steers

 

if air bags. leave red nob in

 

That’s not how air bags and leveling valves work. If the trailer was in fact lifting up the drives as you suggest then the leveling valve would constantly be dumping air to return the truck to the proper ride height.

I’m 34k on my drives and 43.5k on my trailer and it’s not “picking my drives up”.

 

He means when the trailers auto dump the bags when setting the brakes. The locked brakes on the trailer will cause the trailer to push forward and raise the front of the trailer transferring weight off the drives and to the steers.
It gets really interesting watching me scale a loaded tanker. Trucks rocking back n forth 6-8” yet the scale is rock solid steady on the read out. But if I set the tractor brakes it will take 15 minutes for the scale to settle.

 

Oh I gotcha. Yeah I never set the trailer brakes unless I’m unhooking so all that auto dump stuff is foreign to me. Sometimes I don’t comprehend what I’m reading. Lol.

 

I don't pop my brakes on the scale. After all, they don't want you doing it on the scalehouse scale either. May as well see what they see. Your brakes aren't popped while you're cruising down the highway, and that's ultimately the number they're after. In a manual you can shut off the engine with it in gear to keep it in place. The scale should be flat enough that you wont roll anyway, unless there's little tire ruts forming on it, but those should only pull you a few inches until you settle next to the mic, where everyone stops.

 

Don't set brakes on scales. Its level. If the truck rolls, the scales are not level or calibrated.
