What's the right way?

The correct way of weighing it???? A scale usually works best.

My daycab generally weighs around $14k with half tanks. Around 27k on the first box is about as heavy as you can reasonably scale, but this is a single axle tractor. I know of one driver who claims hes scaled 30k on the front box, but Ive never actually seen it done.

I dont really know what you mean by the correct way to scale it.

 

Each single axle you can scale 20k. I dont know where you are getting your other numbers.

 

Scale each axle individually. Steers=12k or whatever the state is, drives=34k and then each individual axle after that....So scale the pup axle, then the dolly axle, then the back pup axle. Each of those can scale 20k.

 

Yeah, its not like in a tandem axle van pulling a 53 foot trailer where your axle limits equals 80k (12k+34k+34k=80k)...In a set like you are describing its 12k+34k+20k+20k+20k but you can still only gross 80k.

 

Here's some info from Cat Scale. Not axle weights, but positioning tractor and trailers on the scale platforms to get weight-per-axle and gross:

They show trailers with tandems, but the same positions are used for trailers with single axles. Yes, you do scale the con-gear (dolley) axle.

If you hit a scale that is only big enough for one axle at a time (some shippers just have the single platform), then you roll each axle onto the platform and note each weight before moving to the next axle. The heavier trailer should go in front.

 

Hang on Ill show you my favorite way to deal with scales.
