Are you wanting the max weight for the vehicle you are driving, or for roads your are driving on?
What does your door sticker say?
What width size tires do you have? How many tires per axle?
Where do you plan on driving?
What is your axle spacings front to rear?
Why did you leave out so much information?spyder7723 Thanks this. -
An ODOT told me this in regard to spreads with the Gross at 80K on the Decal.....
"Treat your trailer like it was Tandem instead of a Spread"......
I was nailed for for being 350 over-axle on my way out at Ashland one day.....A rarity since the S/B coop is usually "Dark".....I was legal on the gross...but my rear axle was bit heavy according to the DOT.....Pop Thanks this. -
So with a bit of help from all the pro's here and the safe driving practices I learnt from my instructor, I'm hoping to be a responsible and safe driver, cus I have already seen some crazy stuff out there. Mostly from the 4 wheeler's!!!! -

Don't go by what's on the sticker inside the door, unless that number is LESS than what's allowed by your state. But usually that's not the case.
Steer axles vary widely by state. MD, for instance, goes by what your tires are rated for.
You can only gross 80k if you have 51' from the center of your steer axle to your rear trailer axle. This is called "outside bridge". You can only total 68k on your drive and trailer axles if you have 36' from your front drive axle to your rear trailer axle. This is called "inside bridge". Of course that's assuming you have 5 axles.
Spread axle trailers are subject to the Bridge Formula. You can only have 40k on your trailer spread if you have 10' of spread, and it reduces 1k per foot as you shrink that distance.
Here is a link to the Bridge Formula. If you pull shorter trailers like dumps or 20' containers you need to be mindful of this.

Example today I drove a T800 with 18k steers, 2 24k drives, two lift axles which are rated at 25k and one lift rated at 16k.
The original axle rates are on the OEM sticker and the upfitter put a sticker that showed the lift axle ratings.Pop Thanks this. -
Hmm I have 13k on my steers empty..... Guess I drive a illegal truck.

I'm at a total loss right now. How on earth does someone even touch a Semi without knowing Axle Weight Limits?
If you're experienced then you should definitely know better!
And if you're right out of school just getting your CDL and/or in Training then it should be very fresh on your mind but your Trainers job is also to help you!
Now, I can understand if you're studying to get your CDL but even then you should have a Study Book already which covers every single detail.
This just can't be a serious question. Those who've given answers are just as guilty for giving in to this whether it is or isn't a serious question.
My guess is this is someone who either is joking around to see how many fall for it or this person has no care to know what his job requirements are so he depends on others. And if he is already a driver then I hope he was at home asking this because if not then that means there's not enough intelligence there to ask another trucker to his left or right whereas he should be parked while typing otherwise he's TEXTING & DRIVING which is worst than any of the above.
I'm not saying any of this to be negative and I'm sure some are going to try and attack me for this but before you do think very long and hard while using common sense about what I've said. This doesn't take rocket science to figure out. It's Common Sense though Common Sense does seem to be a dying ability these days.
C'mon people and help keep these roads safe!
