Weight distribution and adding another axle question

Have you tried turning the tractor around as Im guessing the front is heavier then the back because of the engine?

Also a jeep is located between the tractor and the trailer and a booster is located behind the trailer.

According to the first link of the weight charts you posted with a 4 axle grouping of at least 14' you are good for 51,500 pounds. I also do believe that the 75' max length restriction is dropped when you are running with rigs permitted over 80,000 pounds. Hell even the weight table chart requires a 70' bridge to go 105,500 on 8 axles which is center or front axle to center of rear axle so right there your overall length is pretty much 75-76'. So not sure if your current trailer can do it but look at getting a flip axle installed with an overall bridge of 14'6-15' and you should be good for your 105,500. Also make sure the flip axle can be lifted when its in the flipped down position. And Im almost 100% certain that adding 3-4' overall to rear of your trailer will not be noticed in getting around in the yards you go to.


@snowwy the term you're looking for is flip axle.

 

Who is telling you these max weights? Those weights you are listing are the max weights of axle groups for a legal weight truck.

You can permit 45K on a tandem and 60K on a tridem in ND. Gross weight of 133K max on 7 axles in ND. Done it before with no issue.

With the truck and trailer you've posted pictures of you should be able to permit 12-13K on the steer depending on tire/axle rating. 12-13K on the lift axle. 40K on the drives. 60K on the trailer. Gross of 126K.

 

I wondered the same thing myself, but was almost afraid to state the obvious...
