Ram Payloads- Seriously|||

[dougk53]

Just for giggles on a rainy day while camping went to look at Ram 2500's. Presently have the combination in my signature and it does very well. After a detailed explanation of my requirements the salesman proceeds to bring out trucks that have no bearing on what I was interested in. While the trucks were out I took a look at payloads and was blown away. A 6.4 Hemi Power wagon had a payload of 1700# and a Cummins Laramie had a payload of 1450#. I am well aware of optioning affecting payload and other factors but I am having a hard time understanding anyone purchasing a $66k diesel truck and not being able to do anything with it but carry some 2x4's and plywood. People earn their money and can spend it how they wish but personally I have difficulty seeing a burgeoning market for such vehicles But I am more then likely wrong. Also I am aware of RAWR being a consideration and that the Cummins will pull but seeing numbers that don't even equal my F150 left me at a loss.

Ron, you are correct... Front is a 6K front axle.. truck loaded less 5er is 5500#, with 5er, I add 100# to the front axle=5600#, so I'm 400# under that axles weight rating.
Thanks buddy,
Jim

Yea did not want you to add a heavier cattle catcher and pop the front tires!

Cummins,
Yes you could just the fronts, assuming the rim width is within spec for a wider tire. I ran 245-75-16s on the front of my GM dually, with the stock 215-85-16s on the rear. Drove better IMHO too. I had 6.5" rims iirc. I would not go to a 265 or wider with that rim. You need a 7, better yet 7.5" rim for 265s.
My rig was 4ad too. Tire Siam difference was the same at 30.6" iirc.

Thanks Marty! I will look into this when I get back to WA where I bought these tires.

Exactly what I am saying as well. While I would not want to tow the 17k that it is rated for, I would not hesitate to go over its 2k lb payload. I have done it many times. The truck handled it safely and was very stable every time. The back end wasn't squatting in the rear either. I am not saying the 2500's rear suspension can handle the 4k payload that the 3500 equivalent of my truck is rated to handle, but I am not afraid to put at least 3k in the back which is still well under my rear GAWR.

I had 285's on my 2010 Ram dually with the factory rims. They wore great. It did take a 2" spacer in the rear to keep the tires from touching.

3/4 ton diesels lack payload due to nothing but politics and taxes. The Power Wagon is a special beast and isn't purchased for payload.

^^^^ This is correct ^^^^^^^

Unfortunately with 2500 trucks you really have to sift through the numbers. To be badged as a 2500 the government limits the GVWR at 10,000 lbs. My RAM is a seriously heavy truck....every component underneath is massive. So, at 10K minus the truck weight there isn't much payload......technically.

Now, if you break down the real numbers it's much different. The FAWR is 5,000 and the RAWR is 6,500. So, in real life that is 11,500 GVWR and about 3,500lbs avaialble on the rear axle.

KJ

Nail hit on the head right there !!

AND that's not even considering that it's the same frame/axle/drivetrain ( the nit pickers will be along shortly on this statement....) as a 3500 dually. Tires and springs are the real limiting factors between the HD pickup models.

The front axle rating on my truck is 6500#, RAWR is 9750#.. NOT the same as a 2500, 3500 Dually Axle weights are higher than on the 2500.
SOOO, if you did what was illustrated by KJ, 6500 FAWR + 9750RAWR = 16,250# GVWR.....but not really... GVWR is 14,000#... GCWR, due to Aisin tranny and 4.10 is 39,100#... FAR from the ratings of the 2500.

And it didn't take long.....rest my case. YES, you got 2 more wheels in back and heavier springs. (And in 2013? Your truck got a bigger ring gear, in the same carrier I believe.)
BUT apples to apples for all the GMs and Dodges/Rams that run 11.5 AAM rear axles from 2500 thru dually, everything from the tires and springs on up is the same gear.
Never said the ratings were the same. Mine is only rated for idk 6000-6500 rawr, never looked, honestly, even with all the debating on here. Don't care. It's the same axle, frame and drivetrain as under a dually of the same make and year.
That was my only point.

I hope no one gets your tires for a SRW 2500/3500. Only 3,085 lbs max load for a single? That would drop my rear GAWR from 6,500 lbs to 6,170 lbs.

That's why they got smart and went to 18 and 20's on SRW trucks.

I do wish my front tires had a bit more capacity.

Step up a size or two to give you a little more. 245/75 or 265/70. They are the same height/diameter. Wider and a little more capacity.

Thanks! I will look into those. Since I don't rotate front to rear I could just do the fronts???

The two sizes in my post above are real close to the same height as you OE tire just wider and a little more capacity.

Yep, 3085 rated tires on the front of a heavy Cummins powered dually are marginal at best. Chris
