Went down the hyw today and decided to pull into the local MTO scales just for fun (Our scales are metric)


it maybe hard to read but it says 4290KG

So with me and 1/2 tank of fuel the math goes like this
4290kg=9458lbs
me -230lbs
24gal fuel -170lbs (24x7.1lbs)
= 9058lbs

so if you take the truck rating of 14,000lbs-9058lbs my actual payload is 4942lbs
and not the sticker 4701lbs
there's a difference of 241lbs
which is close to the discrepancy between troverman's 350drw and my truck that we were looking at in another tread "the differences between 350 vs 450"

 

I thought the payload numbers included a 150 lb driver, which would put you off only 91 lbs. I thought it was also a full tank of fuel, which would add another 170 lbs, which makes your numbers off by 79 lbs. I'm sure you've got a few lbs of stuff in the truck (hitch, tools, straps, etc), which would come off that 79 lbs, which puts you within a stone's throw of the factory numbers.

4942 - 150 - 170 = 4622
4701 - 4622 = 79
79 - whatever weight you have in tools, etc. = close enough to 0 to be within specs.

 

Not counting driver weight and adding 170 pounds for fuel (since it sounds like his tank was half full) instead of deleting 170 pounds for fuel, it would put him at 4602 weight available, which is actually 100 pounds less than the sticker.

 

I was deleting 170 lbs from his weight available (not sticker) since he was half full (and not full) and it would take 170 to be full.

 

There's absolutely nothing in the truck only have 1000kms on it i forgot about my ski boots on the floor in the back from the weekend -8lbs?
and the comfort sync thermostat that i picked up -2lbs (The reason for going down the hwy to meet my sales rep)

GUY'S i'm not upset about the weight difference just thought it was funny to be around the same weight difference that we could not figure out between the 350drw and my 450

 

Also back to the 79lbs of tools if that was in the truck when going over the scale and then you took them out it would put me 79lbs further away from my sticker weight not closer

 

How is DEF fluid factored in on this? Would that make a difference?

 

The nearest CAT scale is an hour or more away from me. We have a truck scale at a recycler facility fairly nearby. Next time I'm over that way, I'll see if they will weigh my truck. Would be interesting.

 

Here is what I was thinking:

4942 is your scaled available payload.
Subtract yourself and fuel and you get 4622, which is 79 under the sticker payload.

4942 - 150 - 170 = 4622

That means your scaled payload is 79 (4701 - 4622) under sticker payload. I was surmising that you had some stuff in your truck, which, if it was 79 lbs of tools, and you took those out, it would add 79 lbs to your scaled payload.

4622 + 79 (you took the tools out and added that back to the scaled payload) = 4701

Now, you didn't have 79 lbs of stuff in, but did have 10 lbs, plus maybe a pound or two of dirt, road salt, etc. Not to mention, you have different tires, so maybe they weigh more.

Basically, the point is, you are within 70 lbs (given the 10 lbs of stuff you had in the truck) of the sticker weight. That's pretty damn close for a 9000 lb truck.

 

Correct, I saw what you did and I agree with it, but what he did was incorrect. His truck weighed 9458 pounds with half a tank. He subtracted the weight of half a tank of fuel from the weight of his truck. GVWR is taking into account a full tank of fuel, so 170 pounds should have been added by him instead of deleted. Adding 170 pounds to the 9458 is a weight of 9628. Then we subtract 230 for his weight (it clearly states 2 passengers in front and 3 in back, I doubt they account for 150 pound driver). 9628-230=9398. 14,000-9328=4602 pounds. That's 99 pounds less than the listed label. In other words, the 4942 number is bogus because the OP should have added 170 pounds instead of subtract it to begin with.

 

Gotcha!

 

Spare tire? I don't remember if that's factored or not.

 

Are you sure they weigh the truck with a full tank it arrived at the dealer with 1/4 tank and if these stickers are different from truck to truck then they would be adding the fuel just though math then?

 

I was also thinking about my tires they are for sure heavier than the stock ones so aging this would make my sticker off by that much more also need to remove 30lbs? for tonno cover

 

Stock tires HSR is 62lbs
Toyo M920a are 83.6lbs for the 245's = 86.4lbs more of tire then stock so
my original statement of the sticker being off by 241lbs if you add the tires +86.4lbs and the tonno cover 30lbs=357.40lbs is how far off the sticker is not assuming the fuel tank and driver possible discrepancy
