NORTH DAKOTA - Explain spread axels to em

When you have a spread axle trailer the two axle group are 34000 or 17000 each. Thy need to be spread min of 9' apart to raise the weight limit to 20,000 for for each axle. Not exactly sure on weight # but thats the general idea.

 

Also, keep in mind, North Dakota is 550# per inch on tire weight vs most states are 600# per inch. Two 10 inch steer tires are only good for 11,000#, not 12,000#. And they measure overall length from center of front axle to center or rear most axle. A 70' bumper to bumper 8 axle semi becomes 68' long for weight. I was licensed for 105,500 but my length was only good for 105,000.

 

Depends on the tire size.

What part of the state you going to?

 

Here is a link to the ND axle chart. This helped me.

My understanding is, 20K front ends ok as long as you don't exceed 550# per inch.
It looks like from the chart I sent you the link to, 2 - 18" tires can be 19,800#

 

I think I know who you're working for. But if it doesn't work out hauling sand is really good too from what I hear. I met some guys that came down from Alaska
