I have a single axle truck (Volvo) with a rear rating of 21K.
I have a single axle lowboy trailer that I do not see a data tag on.
The tires are fated at 4K each so thats 16K on the tires.
The trailer has a 24ft deck and weighs around 7k.
What is a ball park on the max I can carry.
I know it has to be a combination of the truck and trailer. I've seen tandem dual lowboys rated at 30-40 ton but the tires are rated at only around 30K so how fo you figure it out?

I got to think semi trailer tires will hold more than that? Are 20' tandem axle single tired gooseneck is rated at 16,000.

I am going to have to assume some things to give a answer.
First of I will assume we are talking about a truck and trailer with a 5th wheel since your Volvo has a rear axle rating of 21k. Then I am going to assume that your lowboy has 15 or 16 inch tires on it and not the normal 20 to 24.5 inch tires of a semi trailer.

So assuming this info is correct.............

Most states will allow 12,000 lbs on the steering axle with 9" or wider tires.
Most states will allow 20,000 lbs on a single axle with dual wheels.
Moving the 5th wheel forward or rearward would adjust these weights.
I would be willing to bet that if your trailer is not home made it has a rating of 20,000 lbs but your tires are pulling you down to 16,000 lbs. Most likely you have light truck tires on it and a thicker ply tire would bring your weight rating up.
Moving the load on the trailer would adjust this weight.

With out knowing the weight of the truck I am going to have to guess at the load weight.
Most single axle trucks I have driven with a single axle 28' pup trailer would haul in the neighborhood of 24,000 load if loaded right.
Since a lowboy or flat bed is heavier than a box pup because of the frame it has I am going to take away 2000 lbs.
Since your tires are only rated at 16,000 I will take away another 4000 lbs.

So that leaves you with a gross load of about 18,000 lbs but you are going to have to work at getting it loaded on the trailer in the right spot.

The truck is a semi, the trailer is commercial made, the tires are 15in on three spoke hubs.
I was thinking that I should be able to go 25K on the trailer???
I have seen trailers rated at 15 ton, but the tires only add up to 16K, so whats the real deal.
I thank every one for the replys, an I know that with all the wisdom here we will come up with a ball park.
If I can only go 10K or so I'm not any better off than I was.
I was thinking if the truck has 21K rears and the trailer has 16K tires I would have 37K minus the weight of the truck and trailer, and maybe have 25-30K left if loaded right.
Am I thinking right?

I wouldn't overload the tires. Shouldn't the trailer's rating be on the VIN tag? The axle, springs and brakes ratings can be figured out, but it would be difficult. But then, it gets back to the weakest part in the system, and that sounds like the tires.

The truck may have 21k rears under it but they are not going to let you go over 20k. That is the max weight for a single axel with duel tires in most states. Now if you stay in Fla. or some other states you can go a little more but lets talk nation wide.
If you have 9" (Metric conversion 216-241) or wider tires on the steer you can go 12k there. If you want to figure your tire capacity use 650 lbs per inch. With out a sliding 5th wheel this is going to be hard to adjust so you will most likely loose some weight carrying capacity there.
While the trailer is most likely rated at 20k or better your tires knock it down to 16k. Even with proper tires they are not going to let you go over 20k here also no matter what the trailer is rated for.
The reason you may see a flat bed or a drop deck rated way over what it can truly haul is because they need to build them to carry small heavy loads put in the center of the trailer to balance out the weight. The flexing trailer under a small heavy load comes into play.

So (with 9" or wider tires) in theory you can gross out at
12,000
20,000
16,000
------
48,000

Now we need to take away the truck and trailer weight. What is that weight??? 17 to 19k????
So in theory that leaves a load weight of 30k.
Now if you haul the same load every time and can play with the placement of the load till you get it just right you can go this high.
But if you do not and can not move the load once loaded you are stuck with making the load smaller.

Like I said before I am only guessing because I do not have all the info needed to give advise. Like tire sizes; total weight of empty truck and trailer; sliding 5th wheel or not.............

In short you may not be over gross with a load but you can still be over axle and get a ticket.

I may have missed something, Uncle said he had a single axle trailer, to me that means 1 axle with 1
tire on each side if he has 4K tires and wheels that is only 8K not 16K also I was under the impression that a single axle tractor with duals can only carry
18K. I know a tandem tractor can carry 34K and 12K on the steering. Did I miss something? THANKS

It's a lowboy with duals on a single axle. The truck is a Volvo daycab with duals on a single axle.

He has a single axle semi trailer with dual wheels from what I understand.

weight carrying is based on tire width with these size rigs but the max allowed in all states that I know of is.....(some allow more)

12k on the steering
20K on a single axle
34k on a tandem axle

In some states you can have
42k on a tri axle and
50k on quad axles

John in LA is about right on the weight. If you have something like a (285-22.5 or 11R-24.5 they will give you 20,000 on the single drive axle and on the steer you can go 12,000 then the tires on the trailer as I read it are like 8.25-15 or so they are a lowboy tire if this is right then whatever they say on the side wall is the limit. Now you might get away with the full 20,000 on that trailer but if you blow a tire or get caught on a scale it's your fine. Now if you are on air ride suspension you can put a pressure gauge in the line for the tractor and one for trailer and use them for very close loading weight and be very close I have tham on my tractor and on the trailer. If the drives read les than 60psi it's good to go if the trailer reads less than about 70psi i'm good and will be right at 78-80,000. If you use the gauges they will pay for them selves and any old well pressure gauge will do the job.
So back to the issue if you go 20,000+16,000+12,000= 48,000 minus the truck empty weight and your there say 24,000 for empty and so payload is 24,000 and better be right or your over on axle just like john in la said.the long &short of it.
