Ok, let me start off by clarifying I know what the towing capacity and payload is on my 2022 Laramie 2500 is, and I know it's more than sufficient to tow my future fifth wheel.

I see such a range of payloads and towing capacity on Rams website. I know there is a difference between diesel, gas, 4x4 vs 4x2, amount of options (added weight). But even if I'm filtering the vehicles to have most of the same options, they're still 500lb + or - differences in payloads. My truck has 2830lbs payload it shows others over 3000lbs.

I've read other makes have much higher payloads and that's due to Ram having coils opposed to leaf springs and different tires could increase payload.

So, how is the max payload calculated? And if it's just leaf springs that would give the same model with the same options different payloads, would changing from coils to leaf theoretically increase payload? Given this, I read payload cannot be changed, but like I said if it can't be changed then how come there are differences?

I've read a lot of articles and unless I'm not searching the exact correct terms I can't find the answer I'm looking for.

I found this response on jaycoowners.com, from 6/28/19, credit to "spoon059"

"There are 2 schools of thought. There is one side that says the little yellow sticker is the bible and you cannot exceed those weight ratings or your truck will explode and kill a bus full of nuns. There is another side that will point out that a 3/4 ton truck is arbitrarily limited to 10,000 lbs GVWR to keep in as a class 2B vehicle for registration purposes only.

I won't tell you what to think, but I will remind you that your 2018 Ram 2500 is the EXACT SAME TRUCK as a 2018 Ram 3500, with the exception of coil springs instead of leaf springs and minor frame differences to mount the coil springs. Engine, transmission, brakes, axles, wheels/tires (assuming 18" rims on your 2500), bolts, exhaust, seats, etc are EXACTLY THE SAME. The rear coil springs are rated to carry 500 lbs less than the leaf springs. Think about this... if you bought the 6.4 gas engine, magically your rear springs could hold 800 lbs MORE than you can since you have the Cummins. That should let you know that your truck is far more capable then 10,000 lbs, but it is limited simply because it was originally meant to be a class 2B truck, limited to 10,000 lbs.

In most every state in the union, you can register your truck for higher than 10,000 lbs if you want to pay the extra fees, and you will be perfectly legal to exceed the arbitrary 10,000 lbs number. There is virtually no mechanical difference between a 2500 and a single rear wheel (SRW) 3500... other than a 500 lbs difference in rear springs and slightly different frame (because of the different spring mount)."

So, how is payload calculated and contrary to what I've read can it be changed?

Please go easy on me, I'm trying to learn. Thank you.

Last I heard when it comes to weight limits the DOT only looks at what the manufacture puts on the door tag, you go over those limits you get a nice ticket, get in a wreck and your over the weight limits and the police & insurance company find out your not going to like it....

Fortunately, since I'm not an OTR driver, I've never even met a DOT officer let alone been pulled over by one.
Were I pulling a trailer for a living I'd be more concerned, cause those poor hardworking SOBs seem to get targeted more than ordinary people...

Well, this topic has been debated for as long as I can remember, well before the Internet was in our homes and there were user forums.

Payload is simple, the vehicle's gross vehicle weight rating (GVWR) minus the vehicle's curb weight. Despite popular beliefs, the curb weight is the truck as built with all fluids including a full tank of fuel but no cargo/passengers/driver. The better question is, how is the GVWR determined? The manufacturer assigns the vehicle's GVWR using the following criteria; the load limits of the suspension system, frame, axles, wheels, and other components that support weight.

The payload of a 5.7L Hemi 2500 Tradesman CC will be much more than the payload of a 2500 Limited CC with the Cummins powertrain. It is the same truck underneath but the weight of the options takes away from the payload. Using an on-site web page likely has many inaccuracies, get the payload info from the truck's placard on the driver's door jamb.

As far as the same parts used on the underpinnings of a 2500 versus a 3500 being the same, I've read that folks have looked up part numbers for driveline components and found different numbers. I don't know for sure if this is true.

I've also read that GVWR determines registration costs in the various states and exceeding a payload number that resulted in an injury accident is a felony in some states, Flordia is one of the states.

You have to find your balance between empty driving comfort and loaded driving comfort. How often will you tow near your payload. If I'm a few hundred pounds over payload, and I tow often, it would not concern me. Going much beyond that would not be my choice. Capacities also affect vehicle stability when towing, something you really want to maintain.

I bought a 3500 which has a 4,000 payload rating, and I tow a fiver that has about 3,000 pounds of pin weight. I would not put this weight on a 2500 and I don't think many would knowingly. I've camped many times in Michigan's upper peninsula and the number of 2500s pulling large fivers is amazing. When I was looking for a tow vehicle, no one had 3500s on the lot, all the HDs were 2500s. Car dealers and RV dealers are the last resources to use when looking for advice on capabilities.

The real difference between a 2500 and a 3500 outside of a few hundred bucks is the truck's unloaded ride manners. Then think about coming down a long mountain pass towing a fiver that is 1,000 pounds over your payload and you can feel the instability of the truck. Hopefully, this post provides a few bullet points to consider when deciding what is the best solution for your use case.

Minimally educated opinion:
From the reading I've done, I think just looking at the truck hold the load is enough to determine if it's too much (if it has unaltered suspension). Mfgs put springs on it that are well below the factor of safety of the rest of the related components. Beyond that, just feel how it handles and brakes. If it feels squirreley, then something's being pushed too far.

edit: pretty sure duallys have nothing to do with load on the tire? just stability and maybe weight per tire for DOT reasons?

Last I heard when it comes to weight limits the DOT only looks at what the manufacture puts on the door tag, you go over those limits you get a nice ticket, get in a wreck and your over the weight limits and the police & insurance company find out your not going to like it....
Bet this is the very first thing insurance companies/ lawyers look at if there's a wreck. I would. Even if I'm at fault. I recall a story where a drunk driver was driving perfectly when somone crossed the centerline and caused a crashed. Drunk driver was deemed at fault.

Yes thank you, I did mean GVWR not payload, and correct I found a lot of threads in regards to this topic..What you wrote helps a lot. I'm amazed how fast options add up weight.

There are many misleading posts in regards to increasing the allowable payload. I know bags and tighter springs will only help the rear hold more weight in the essence of sitting level as opposed to squatting, but not increase the actual payload.

I would be interested to know if there truly is, and what is the differences between a 1 ton and 3/4 ton truck that would make it structurally safer to carry the extra weight. If it is just tighter springs/leafs? tires? Is the frame thicker? Stronger components? If any of this could be modified to a 3/4 ton to make it hold the same way without having to get a new truck. Then at the same token what type of legal aspects would have to be changed, would it be just a matter of registering it to a higher than 10,000 lb truck? Not saying I want to do any of this, but if it were just simple it would be nice to do, but then have to register it differently as well. Just curious

I know when I was looking for my truck, the SRW had a GVWR around 11,700 lbs, and the DRW had a GVWR of 14,000. As I was looking for 5200+ lbs of payload, and the SRWs I could find were all in the 4200 range when optioned out, I went the route of DRW. That extra 2300 lbs of GVWR only netted me a little over 1000 lbs of additional payload. Those two additional tires are not 1300 lbs, so there must be something else different in the truck.

I know the differences between my current 3500 and the 2020 2500 I had prior. Both Rams had the CTD 6.7. The 2500 had 2097# cargo capacity with 6000# front axle and 6040# front axle. The 3500 has 4058# cargo capacity with 6000# front axle and 7000# rear axle.

You don't need to be an OTR drive to get pulled into a scale house, back in 2012 I was stopped coming out of Missouri into IA, I was pulled over by a IA state trooper in my 06 2500 CTD while pulling a 20 ft flat bed trailer (truck & trailer had IA license) he had me follow him to the nearest weight station to be checked, I was legal on axel & gross weight based on manufacture door tag that was checked by weight master, I got really lucky the weight master didn't give me a ticket for lack of proper tonnage purchased on my registration, I was over weight by IRC 300 Lbs, he could have written me a ticket but did not, its not common thing to happen but it does happen when you lest expect it, its another reason why I watch weights when hooked to any thing bigger then my small 14 ft trailer...

I can tell you that traffic court will only go by the sticker, regardless of modifications. I've seen people argue it and lose 100% of the time.

That is clearly a lot of difference between the two rears. With all the added components on the rear for the 2500, that's a lot of extra weight added on. How much does that account for the payload difference or is it just because of leaf springs? I'm not talking about towing, just payload. Why can one truck hold more weight in the back than the other? Take GVWR out of the equation and if registrations and Dot's didn't matter what makes one able to hold more weight in the back than the other? Not just between a 3500 and a 2500 but between brands, cab sizes etc. Let's just pretend for argument's sake that we just have a bed of a pickup truck with the rear axles no cab for comparisons. Like some guys make the rear into trailers, if they were all lined up, could they all hold the same weight?

One thing directly that matters directly pertaining to axles are gear ratios also.
Your last question comparison is called Rear Gross Axle Weight Rating. You also then need to consider tire weight ratings.

Seems pretty straight forward. The weights that the manufacture has posted are the ones which have been Tested and Certified under specific conditions ( weight, gradient, speed, temp, altitude, etc, etc, etc). It’s a Standard for testing to keep the playing field equal for all manufactures.

Is there a ‘Safety Factor’ built in? Very likely yes. Will they publish that? No. Why…. because everyone will use THAT value as the new limit.

If they could, the manufactures would want the Highest limits possible, as that takes their product up a notch over the others

Can you modify your truck to tow more capacity? Of course Yes.

Problem is…… you have just become the new Crash Test Dummy and taken upon ALL liability should **** happen. Which is why Insurance Companies will say Adios….. your on your own. :waytogo:

Until recently, each auto companies Engineers set the weight limits
The Engineers did not come to an agreement until recently

Ford for several years carried the Best in Class Weight Pay Load & Towing capacity & it was untrue.
The other companies complained that Ford was fudging the numbers

A agreement to set the weight numbers was decided upon, was called SAE J2807 towing standards

Ford fought the agreement for several years
The argument was so heated, that one Truck Manufacturer, would not sign the agreement until after FORD had signed it, because if they signed it first, Ford would do something like we got you sùcker, and not sign it at all.

After Ford signed the agreement, they realized that they had to shed a bunch of weight to hold onto the 1/2 ton weight standards.
So the following year, Ford went to the Aluminum bodies

This may cover what i just wrote

I have to agree and also state: RAM payloads are too low.

..... That should let you know that your truck is far more capable then 10,000 lbs, but it is limited simply because it was originally meant to be a class 2B truck, limited to 10,000 lbs....
I always thought this was stupid. Chevy and GMC 2500s are available with configurations of 10,450 and 10,650 on gas engine trucks and diesels 11,150 and 11,350. You have to select the option "lowered GVWR, 10,000 lbs" to get only 10,000 pounds.

In MN where I live:
"!Person declaring “personal/non-commercial use only” can register in the “Y” non-commercial truck class for registered weights of 10,000, 12,000 and 15,000 pounds. There is no difference in the registration tax amount; it is merely a plate designed to allow the owner to declare noncommercial use which is exempt from the USDOT number requirement"

Note there is "no difference in tax" as long as it's for non commercial use.

In your search you have read countless comments on this topic. In the end, the number on the sticker is what Ram has certified your truck for. Doing anything else is guessing that it won't lead to a problem down the road, and anyone's response about their exceeding specifications for their truck has no relationship to your specific situation. Numbers in online charts are for a uniquely configured vehicle, you would have to find that exact provisioned truck to get the towing presented; essentially don't refer to those charts to help figure out anything in a driver's specific vehicle. Run your rig below the door jamb stickers and you should be fine. Exceed those numbers and the risks increase.

tow packages, gearing, trim package, etc all come into play.
BTW; Tradesman grill allows a touch more air flow to cooing components, and also doesn't come with some options that add a pound here and there.
