2025 2500 with 11,040 GVWR/over 3k diesel payload?!

[johnmyster]

Not quite the same. The increase to the GVWR on the MC 4x4, to 12,400, was done around the frame/suspension change in 2013. The current 2500 increase to GVWR is nothing more than a sticker change.

All SRW different cab/bed/drive configurations have different GVWR’s, not just the MC. Oddly enough the MC lost the 12,400 GVWR at some point and not it matches the CCLB 12,300 GVWR.

Except that it kinda is the same. The 2500 suspension capable of 3k payload was already there. In other words, the suspension (and now the gvwr) are scaled against curb weight so that payload capacity stays relatively equal across many configurations.

The 2500 was mostly up against the 10k limit, so it mostly didn’t get a gvwr that scaled with configurations/options. I guess there were some 9k models and that 9900 Canadian thing.

The 3500 SRW wasn’t up against an administrative limit, so they scaled the gvwr with configurations/options.

The DRW scaled until it hit the 14k administrative limit.

So for the past 10+ years the 3500 SRW was the model that got a relatively fixed payload capacity across configurations. Now the 2500 appears to get the same.

Yeah the cutoff is in the build date. Yours was built in February hence the lower payload.

Yep, just showing for people. What's crazy is the recommended pressure now. I drove home from DC, about 3.5 hours on the highway and them ****s were like 93 psi hot. Got home and put them at 62f/60r cold. I can't believe they recommend 75/80, the tires MAX psi is 80. I was getting worried.

They only recommend 60psi for mine ‍

Similar but different for sure. It’s how it should have been for a long time on the 2500’s, and even 3rd/early 4th gen’s… probably even 1st and 2nd gen’s but I’m not as familiar with them.

Max pressure is cold psi, it’s perfectly normal for a tire to increase pressure when driving and that increase isn’t bad when it’s above the sidewall max cold inflation pressure.

You have the small 245/75R17’s, they need 75/80 to meet the axle weight ratings.

Nothing new about that tire pressure being recommended.

Bigger tires means less air pressure for the same weight.

I personaly put my rears at the tires max of 80. At 80 the ride sucks empty but it is more stable loaded.

I guess you don't mind a rough ride I run my 2024 2500 6.4 at 55 front and 50 rear, and will probably drop them another 5 lbs. Even on my 2018 3500 CTD, I ran low tire pressure while empty.

On my CTD’s I ran 55/35 empty and the Hemi is 40/35. Even loaded I don’t push them to 80 unless the weight calls for it.

It’s really annoying to run overinflated tires once you’ve started running proper pressure.

I run mine 50 front and 45 rear when unloaded. I have the base 18" wheels. No way I'm running high pressures when unloaded. I like my back too much.

For example, back in 2006, a GM 3500 SRW truck would have had a max GVWR of 9900. The 1-ton pickup was the "under 10k" category truck (9900 canada) for companies/users that desired to be under 10k. The well optioned (diesel 4x4 crew cab) configuration was about 7k curb, so that still gave you a good payload ~2900. Logically a 3/4 ton needed to be less than that, so GM quasi (de)rated the 2500 to 9200 pounds, which handicapped the 3/4 ton models that had essentially the same curb weight. So even there, the 10k threshold (9900 canadian) impacted how it all shook out.

It wasn't too many years before then that even a DRW truck was 10k GVWR and likewise, SRW and 3/4 ton models staggered in below.

And of course tire capacities influenced it all too.

Over time, the DRW became >10k, eventually the 1-ton SRW jumped the threshold, and now the 3/4 tons have done it as well. I think Ford did it first with powerstroke HDPP trucks, then GM followed with the duramax 3/4 ton HDTP configuration. Now we have 3/4 tons available >10k across the board (depending on equipment) unless they're ordered with the 10k derate option.

So the 10k threshold has a long history of impacting ratings space.

I have to drive up to Phoenix Saturday, so I'll drop mine down to the same. Thanks

I did leave that a bit open ended did I. I don't normally use mine for daily driving, most of the time it has a trailer on it that results in 4400 rear axle weight with the trailer empty.

With even one car it can result in a max axle weight which is also max tire weight. Unless it is a light car like a honda civic I need to put the first car back towards the middle.

I was fortunate to be able to pick a NH DOT cop's brain and being overweight is one of the most common violations, second to exceding daily driving hours.

If you are at limit but have under inflated tires you are overweight legally speaking. As you know a tire is rated at its max pressure and that is what they look at.

When I first started I had the pressure at what the door sticker called for. When I increased it to 80 it became more stable.

I run the front at the factory setting because I know I will never be near the front axle weight limit.

Is it odd my axles are 5750/6000? Are other 2500s all 6k front?

I wonder if the front springs are different than on the 6K front axle? I am running a Thuren 1" lift coil in the front, which is softer than the stock spring, and does not seem to affect my hauling, since I either pull a GN or bumper pull trailer, rarely put the load in the bed itself...

I'm replacing the springs and shocks with a Carli kit anyway this weekend, I just wanted to make sure I didn't have a worse axle or something. I got the base suspension for the Tradesman since I'm ripping it all out anyway.

Anyone heard or know if Ram is going to send out updated stickers to those trucks with the 10000 stickers since clearly there were no hardware changes? I'm guessing not but it would suck for those using a 2025 with the pre-new certification getting a violation if they exceed the "old" sticker when the truck is newly certified.

Doubtful Ram does anything retroactive.

I’ve never found a state where you are legally bound to GVWR, just axle and/or tire limits. (For personal use)

There is no certification process for GVWR, only GCWR.
