Maxing out your truck’s payload

[nickw]

So maybe I'm missing something, or you are completely illiterate...

But I answered the ONLY question you asked.

Yep, just one question in there.

You didn't answer the main question:

".....outside of tires, how would you know what those things are "rated" for but more importantly what loads they encounter on a daily basis?"

Care to give it a shot or you just going to dodge the question?

Throwing around insults speaks volumes to be honest.

 

[nickw]

A rather large part of these ratings is dependent upon usage

Take a typical load E tire for instance. Its ratings are based upon a few things...

Inflation, load, and speed. All are factors that will determine how much heat the tire will generate.
Since this is a tire, I assume 100% duty cycle. As in, the tire will perform essentially forever without failure when operating within said limits (load/PSI/speed)

Decrease inflation with all other things constant. Tire failure
Increase the load with all other things constant. Tire failure
Increase the speed with all other things constant. Tire failure.

Eventually......

But when constants change, the results change.

How about increase the load but reduce speed?
Or the one most here SHOULD be familiar with.... Decrease inflation and reduce speed....
Or even... decrease load and decrease PSI?

Its all related. And can be applied to essentially any part of a machine or machine as a whole.

Tires lasting 'forever'? Bigger loads = lower miles and if you go offroad often you'll get even less.

Already answered. Maybe you forgot. Each and every component/item in that list is the same as those used in trucks with higher GVWR. And even when pushing those GVWRs, you must still factor in some margins.

In the backcountry now. Ill update with specifics when I have a proper signal. 😉

Hey, anything we can do to help remedy your ignorance

Here we go for starters.

snip #1
2011 model year
The F250 and F350 regardless of options utilizes the same trans, the select-shift 6-speed, along with the same gearing.

Snip#2
Same year, showing difference GVWRs, with SRW F250 and F350 highlighted.
Next shown shown is front axle rating (Dana Super60) that shows the rating for a 4wd is the same for F250, 350, and 450
Also shown is rear axle rating (Sterling 10.50), but shows a magical upgrade in GVWR between F250 and F350, even though its the same axle.
Finally, front and rear brake rotor sizes, identical between F250 and F350

And do notice the under/over 10k gvwr note

Parts snips...

Front rotors, showing same for F250,350,450, and 550
Front calipers, same for F250/350
Front wheelbearing/hubs, same for F250/350

More Parts snips...

Rear rotors, same for F250,350,450,550
How about an upper ball joint? Same for F250/350/450/550
Front shocks, same for F250/350
Front stub shaft.... Same for F250/350/450/550

Dude, after reading your post detailing your recent suspension "upgrades" and reviewing your pictures - I wouldn't let you change my air filter. Seriously, your trucks suspension is questionable, at best, and you claim you are a person who can increase GVWR?!?

Interesting lift block in the rear - I can assure you that will not last.



And your rear air bags and mounts - who installed them?

 

[IdaSHO]

Uh, nobody has claimed to increase GVWR. Only take the ratings with a grain of salt, and understand the actual limits.

As for the upgrades, those blocks have already seen 20k miles. 3/16 box tubing with welded struts within them. They are as they went in, and are in no way failing.

The bags are installed as per MFG, and while the hardware is terrible, they have near 50k miles on them without problem.

Thanks for the concerns btw. 😆

 

[IdaSHO]

And here it is 20k later.

"I can assure you that it will last"

See, I can do that too. And considering the ages and likely mileage of each of our trucks, Id say my claim holds more water.
Anybody can buy a brand new truck, bolt on a bunch of fancy parts and go on an adventure.

And here we go for more...

Let me know when you want me to stop, this list is near endless.

PS Pump Same, F250/350
TRE Same, F250/350/450/550/600
track bar bushing Same F250/350/450/550
torque converter, Same F250/350
trans clutch pack SaME f250/350/450/550
Drag link, same F250/350

Shall I go on???

The F250 and F350 share parts - ok, we knew that, just like all the other 3/4 & 1T rigs.

You can't conveniently pick and choose what parts cross over to make your point from one brand in select model years - many parts don't crossover to the 450/550 platforms like rear axles, they are using 110 and 135 axles now, pretty sure RAM does too.

You state brakes are the same but the literature you provide clearly shows the 450 having larger brakes both front and rear - may wanna check your work?

Are you sure the front axle is the same? Not according to this:

"The F250/F350 and F450/F550 Super Dana 60 front axles share many common parts, but the axle shafts, steering knuckles, wheel hubs, and brakes are different"

The rotors are not the same, the calipers are not, the rear axles are not, front axle is not, torque converter isn't, wheel bearings are not, power steering pump isn't, frames are not, suspension isn't but the TRE are and the shocks are....so I guess you are right? What about the windshield wipers, glove box door and muffler bearings?

I don't have time to look all this BS up or pour over your false claims - so yes, your truck is the same as a F550 obviously, you happy?

you stick to highways only?

Not at all. Most recent trip we just returned from included near 90 miles of off pavement. 😉

Nowhere did I claim it was a 550. What I did claim is that nowhere am I exceeding the ratings of the components as each component is used on trucks with greater GVWR. In which I am 100% correct. I know, reading comprehension is tough.

As for accuracy, 2011 is a changeover year for superduty. As indicated by years of application for some parts. Fits older 450/550 and newer 250/350. So even Ford doesnt have things 100% sorted out. Parts stores are likely more accurate with crossovers, but are still likely not 100%.

Have fun.

Remember saying this? This is where it all started and what I disagreed with:

"Nonsense. Running at max GVWR on the highway isn't taxing anything near peak on a truck unless you are hitting a legit, and long, 6+% grade, or operating continuously on legit off-road.

Start from the ground and work your way up...

Tires
Brakes
Hub/wheel bearings
Axle housing
Ring and Pinion
Driveshaft and U-joints
Trans
Clutch/Converter
Engine
Chassis

I run at or over max GVWR all the time. Nothing on that list is near its max rating. Nothing."

Using YOUR data the things highlighted are different between the 250/350 and 450+, so you are flat out wrong using you comparative analysis since Ford upgraded components from the 350 to 450 why?

 

[tacollie]

It's pretty entertaining how there are people traveling the world in Tacomas 1000lbs over GVWR and people who say running a 1 ton truck at more than 75% GVWR is asking for trouble. My F250 is currently sitting at 97% GVWR. I'll let you all know when the wheels come off if I survive🤣
