GCWR

GCWR=Gross Combined Weight Registration
GVWR=Gross Vehicle Weight Registration
Tractor + trailer + load must be 80K or less, unless registered for a higher gross weight in some states.
You now need to know the actual weight of the tractor and the trailer. Say it is 32K for the tractor, 10K for the trailer, which equals 42K , which is your TARE weight. 80K - 42K = 38K for the load.
Remember, these are just examples, so weigh your T/T to be able to see what you could legally haul.

 

You are not wrong.

 

GCWR is your “Gross Combined Weight Rating”

 

Some tractors and dry vans have a GCWR of more than 80,000 lbs by themselves. The GCWR doesn't matter neither does the GVWR unless you are in say a GVWR or GVWR restricted lane or crossing a weight restricted bridge as @MACK E-6 mentioned. As far as a scale goes (at a scale house or roadside portable) what will matter is the actual weight of your truck, trailer and load. Long as you are at or under what you are legally registered for, you're good. If you are over then you will get a ticket.

Just because the GVWR or GVWR of your vehicles states the weight numbers on the manufacturers plate doesn't mean that is what your vehicles are registered for. You'd have to actually look at the registration to determine what weight its registered for.

 

I dont know what u are trying to do. Just register the truck for 80k . like every other truck on the road and be done with it. The government is stupid and you will run into problems when trying to do something outside of normal

 

The GVW sticker of the truck and trailer simply state what weight the truck and trailer were engineered to handle. It doesn't mean you can legally haul that much though. I believe you'd just register the truck for the max in your jurisdiction or the max your truck and trailer are rated, whichever is lower. You probably don't want to register it higher than the truck/trailer ratings though, you'd be overloading the axles and risking more than just damaging your equipment.

 

Yes, the R is for rating. Sorry for the confusion.
