I've watched some of his videos before.

This video shows him talking about how the weather conditions are poor and visibility is low, but he's making a "driving rant video" anyway. In that video, he runs a red light (at 2:25), drives 10 mph under the flow of traffic creating a hazard in poor conditions, then brags about how he has "spurred shopping awareness in people" that weren't aware before.

He's just another YouTuber who takes himself too seriously.

thats a WHOLE lot of trailer behind the axles, talk about rear end swiiiiiing

If you are exceeding your gross weight rating, you WILL be over on an axle.

Doesn't matter. You cant cherry pick your numbers. The max is either an axle or the GVWR. You are not supposed to exceed any of the numbers.

i use axle or tire max. those are the legal limitations, unless your in a state that uses licensing . everyone should do what they think best.

Yeah using the trucks RAWR is the safest route and its legal.

According to my state size and weight officers a out of state non commercial truck may have a high or low registration number. This department could care less about any kind of weight number on the vehicle registration papers. This state has no type of number for registering a non commercial vehicle. Just the tow vehicles mfg steer and drive axles and the trailer mfg axle ratings will be enforced.

I see where some one always saying his gas 3/4 ton 10000 gvwr has a 3600-3800 lb payload.

Or a one ton SRW with 12k+ gvwr and a 4xxx lb payload.

And Fords F150 HDPP with a 7850 gver and 3200 lb payloads.

Add those high gvwr based payloads in the bed or behind or over the rear axle to those trucks above can overload the trucks RAWR numbers.

RAWR is the lessor of the trucks rear tires/wheels/spring pack and the axle ratings.

As a old(er)mechanical engineer I say watch and respect the numbers. Better men and women then me spent time figuring them out. Peace Out. Ed

I have had many of those "holy" experiences driving commercial vehicles in the feed business, and steel industry. Many of the same principles apply, and the rules are the same. I know the feeling of losing an axle while driving (loaded) I know the feeling of losing my brakes (and seeing a bus pass through the intersection just before I blew through). Please people, educate yourselves and use the best equipment you can afford. And I was a Volunteer Firefighter for almost 10 years, and have seen some nasty injuries from all sorts of "mistakes" and "miscalculations". It sucks learning the hard way!

That's what I was trying to say to the poster I responded to.

that is a manufacture position, and personal opinion/ position. not a legal one. people keep trying to make their opinions law. [emoji849]

frt axle max - 5600

combined - 12650
max gvw - 11600

yes??????

Obviously we are talking about two different things. My math is fine. Reread my post. I wasn't speaking to your specific vehicle.

[laj]

you said If i exceed my gvw its mandatory for me to be over on at least one of my axles. gvw is 11600, if i max out my axles my gvw is 12650. where did i exceed my gawr? all my p/u’s are that way. the manufacture’s do that on purpose. its called margin

You are still overweight. Your gvw should be the sum of both axles...

It used to be like that, but they aren't like that anymore for all pickup trucks. In fact, that's how GVWR was figured out. Just add up your axle ratings.

I am not a gross weight expert or really even moderately knowledge.

My question is max weight the sum of the axles? But what if the manufactured of a vehicle that the axle is not the weak link?. For example if the manufacture supplied the vehicle with lower rated tires, for example, to reduce cost and sell to a specific market. Then the max numbers would be lowered by the manufactures, with tires as the cause. In that case the sum of the axles would be incorrect. Do the manufacture consider all things when specifying a max number, ie axles, tires, braking, chassis and so on?

It is a question, I do not know answer.

this is why i don’t exceed tires or axles. on all the srw 250, 350 p/u’s i have had the max tire load was always above gawr
