How much weight would you haul on 6 axles

In Idaho on an annual you would max out around 140k. Wyoming will go 65k on a tridem and 55k max on tandem drives plus your steer without having to go through Cheyenne. Some states like Nebraska I believe have a 20k per axle max.

 

It's really going to depend on your truck. Standard highway tractor with a 13.2K steer and 40K drives probably weighs about 23k max. 55T RGN going to be somewhere around 20K. So about 43K tare weight.

A lot of states will let you permit higher but like Oxbow said some states are max 20K per axle.

So your max permitted weight will be 113.2K in those states. That would give you about 70K worth of payload.

If you had a heavy 3 axle tractor with 20K steer you could probably get about 75K on the deck since the truck will be heavier. Would also need to make sure your trailer has a long enough neck on it to transfer weight to the steer If you went this route.

 

every state and province is different. I have found states as low as 40k on tandems and 50k on triples

 

Almost every state is different. Most states are 60k on a tridem and 40-48 on tandems. Doesnt matter how much your trailer is rated for if you dont have the axles on truck/trailer....

 

I can get to about 110k on 6 axles. I have a 10-2 neck on my rgn tho. Wanted a full 30 foot well and a 53 foot tri axle. Short neck is a down fall for steer tire weight. Does anyone know if the DOT ever hassles ya for over 40k rear ends with 45k on them? Always wondered.

 

I don't think so, at least not in my little corner of the world.

 

I’m sure it could happen but never heard of it and never had one look at my doorpost to see what it says. I deliberately try to have 45-50k on the drives which in my case are 46k axles and assuming they don’t know by looking they’re not worried about it ( if I made any sense here)
To answer the op
I can permit 120k on an annual permit in Illinois with 6 axles with no questions asked. I got 150 ish a couple times on 7 but rarely do anything that big.
so with a 120k permit I can do 79500 on the deck with this setup
