Straight scoop, What are the differences in a 3/4 and a 1 ton chassis/ suspension?

[GAmes]

You can't exceed the GAWR (AXLE) front or rear, just because you put on higher load rated tires don't enhance the designed braking power for the GAWR!

I have and I can. There isn't any difference in the D80 on my truck and the D80 in a '99 that came stock with 235/85 load range E tires. If someone that has a '99 duelly would be so kind, would you post the door sticker weight ratings for the rear axle?

So what do you use? The door jam numbers are NOT the same for the same axle depending on other items.

2500 reads 6,000 lbs
3500 SRW reads 6,200 lbs
3500 DRW reads 9,300 lbs
AAM rates the axle (SRW or DRW) for 10,912lbs.

So tell me which rating do you go by?

The brakes are the same on all 3 door jam ratings, so that point is not valid.

Got a link to these rules you are talking about?

Braking is more the key between the different years vrs same axles. The third gen braking is leaps and bounds over the first 2nd gen's. GAames, you might not want to do that in Comifornia, I've seen a more than one car hauler sitting at the scales, if you have a gooseneck with a regular bed, CHP don't want you in the scales, but without the bed your considered to be a tractor. You can and you will, so I don't care, it's your thing, I'm not being sarcastic, just posting what I've been taught pulling 80k. So what your saying is you can take a 1" rod and somehow attach a set of E load tires and rims and pass through the scales.

Again, and again, and again. The DOT does NOT care about your rating on the door jamb. They care that you have enough tire to carry the weight, that you are within the 20,000# single axle limit, and that you have licensed and paid for the weight you are carrying. The door jamb means NOTHING to them!

They also normally only check commercial vehicles too, not RV's.

This is US, CA may be different!

So if I can somehow fit a Rickson 19. 5" conversion on a 4 cylinder automatic Ford Ranger, I'm good to tow up to the limit of the 19. 5" tires?

I really doubt a DOT guy will care if you are driving an older dually rated for 10,000 GVW or a '13 rated for 14,000 GVW. My old '74 Ford dually is rated for 10,000 GVW, no GAW's listed.



Nick

This is what we are saying.



Rusty,



If you license your 2011 Dually for 38,000# the same weight Dodge says is okay for the '13 Dually, then run together, that DOT won't know or care what the difference is.

Nick,

My question regarding the Ford Ranger still stands. I can find just as many "professional haulers" who state that increasing tire load ratings doesn't work above the vehicle's GAWRs as those who state that it is ONLY the tire/wheel load rating that determines whether or not one is legal. So, in my Ford Ranger example, if I'm adequately licensed for the weight and have those 19. 5" wheels and tires on it, am I legal up to the tire load rating, or is there some other determinant that is going to be used to recognize that this truck would be dangerously overloaded?

I am amazed that Dodge used 17" wheels & tires on the new 3500HD.

I think the clue would be the oil spill under the truck from the broken differential plus the bumper being on the ground.

Is the Ranger legal or not?

The 2 3500's I looked at both had 18's tire rating was over 3500 ea

 

[Bob4x4]

That is why I specified"in the US". I am aware of BC laws. Here, the only part you got right is licensed weight, and that isn't inclusive. As Nick stated, it is only enforcable in the state you are registered in.

Do you think the GVWR and GAWR are not exeeded on this car hauler?

View attachment 85291

I have customers that are carrying 5 cars ,they are going through the scales so it must be ok ??

 

[NIsaacs]

The 2 3500's I looked at both had 18's tire rating was over 3500 ea

Were they SRW's or duallys? I would think that 17's would have more than enough capacity for the 14,000 GVW dually.

[RVTRKN]

Well I'm just going to sit on the sidelines with this subject now, but before I do, the bottom line is GAWR, steer and drive as well as trailer axles may not exceed the GAWR. I'm not going to tell anyone here that they can't or lose any sleep over it. Its not just tires they look at, when a trailer manufacture builds for the GAWR they must comply with brakes capable of stopping that weight. That is why we can haul as much as were lic. /registered for even though Dodge GCVWR has been exceeded, but the GAWR may not be. The statement about the Ranger is a good example, and when you pull into the scales with it hauling a 28K pound trailer and it manages to make it intact, besides being laughed at, it will pass as long as the GAWR for all four are within that. They don't have some magical system that will tell them what every manufacturer's GAWR is but when red lighted and pulled into inspection, you run a chance of them checking that, and a Ford Ranger pulling 33K GCVW might get them suspicious, but now if it has a V6, well then, its all right. :-laf:-laf:-laf



BTW, Rusty that 2300 POS four cylinder can't even tow its own weight empty, I owned two of them, Carbureted and Fuel Injected, and they just are gutless wonders.

The reason I use the Ranger is that I actually saw a Ranger towing a 26' or so 5th wheel westbound on I-10 between Houston and San Antonio. We were eastbound towing our 5th wheel, and I looked over to see him with the rear of the truck on the bump stops, the nose pointing at the sky and blue smoke pouring from beneath the engine compartment, doing about 40 MPH or so. I don't know how far he made it, but with my luck I wouldn't have made it 10 feet!! It was so absurd that my wife noticed it first and said, "Look at THAT!!"

Nick, if the Ranger in my example isn't legal, why not? Because it's so far in excess of its door sticker manufacturer's GAWRs? If not that, then why is it illegal - what would the license and weight boys cite it for? After all, it's within its tire/wheel load ratings.

single wheel both 2 and 4 wd

 

[Bob4x4]

I did a very mild build on one and swapped it into a Mazda pu It would peg the speedo even with it's 4. 10 gears and no overdrive. I wish I had a pic of it pulling a trailer with 4 3 wheelers and 2 dirt bikes

Rusty

It would be illegal because it would be unsafe... . however if you overloaded it in moderation/reasonable, you could haul double it's rated payload and not get looked at. Say... 10 ply tires and airbags, with a chunk of copper about 3,000# that you couldn't even see and go coast to coast. It is a lot about perception. If that 3,000# was a full size 9' overhead camper, it would probably get stopped.
