Truck Dually Wheels

And you are 100% positive that if it only had 2 tires on the rear it would have went over.......:S Do I even need to find a picture of a DRW upside down? Maybe they need to put three tires on each side of a class 8 truck. Might keep them upright.

I see The Mad Norsky has not forgotten.

for the benefit of transamz9 & others who think that beefing up a SRW with airbags & such compensates for real extra width & stability when faced with a real emergency that cannot be ovecome with pulling power or braking power either, here it is.

Hurricane force sustained gust of wind hitting a heavy 5er broadside. The 5er had something like 80gal water in the low mounted tank & also a heavily loaded 12 cuft fridge on the windward side.

This is why I get rather passionate whenever the SRW vs DRW subject comes up. I will never forget the sound of the kingpin tearing out of the 5th wheel.







That was no 'barely meets specs for the trailer' hitch. It was a 20,000# hitch.






The truck stayed up on the highway. It mowed down a couple of those snow posts but it did not go down with the trailer.

The answer is the same. If you don't have enough for the the worst case scenario that suddenly you are faced with, you have bought the wrong one. If you bought anchor suitable for a 25' boat in extreme conditions & your boat is 35' do not be surprised if it drags & you are on the rocks.

Likewise, if you get hit with a huge gust of wind broadside with your SRW & get blown over, don't be surprised. That extra stability of the wider DRW could very well have kept you upright. Physics.

In that split second of your world getting turned over, thinking 'I should have bought a DRW' is too late.

The wind must be different around here. It blows my DWR truck around empty just like it does my srw. My drw truck weighs about 3500# more too. Go figure.:S

You do realize that Veebyes had a fifth wheel ripped out of his truck by a huge gust of wind in Wyoming?????

Had he not been driving a dually pickup, chances are the truck would have gone along with the fifth wheel.

I've seen the photos he posted. A terrifying moment indeed. The fifth wheel ended up going down a steep slope along the interstate and demolished itself rolling down the slope. His truck stayed on the road.

All fine and dandy but IMHO you are WAY light on 18.3% pin.

When you load most 5er's a lot of the weight goes to the pin.

Those figures came right out of the thin air, figments of my imagination just used as an example only.

But they clearly show how one could find a number for pin weight using numbers all the manufacturers have posted about their fifth wheels.

Get the right tools for the job. I like to use my truck as a moderate 4WD at our destinations. A dually just is not that good in the mud, or on narrow roads. So, I am backwards from most folks. Our 5ers will always be towable by a SRW and it will be a super cab with a standard bed. This is about as big a truck that I can manage on crappy roads. Of course this is the type of company truck I used in the oilfield. Your Mileage may vary.

I'm like you. I like to have a truck to drive when not towing, so I purposely set my sights on FWs that will fit the truck I have/want. Right now I'm in a maxed out 2500HD with my current FW, which is =heavy=, for all that it's a low profile with a fairly light pin. I realize now that, had we bought the 2-slide mid-profile model, 4' longer, I'd be =way= overloaded and would have spent a couple thousand in beefing up an inadequate truck. My goal is an early 2007 3500HD SRW and I'll buy a FW to fit within its specs.

After reading the link on pick ups, it is about as clear as mud. All of the newer DRW trucks have a GVWR over 11,500#. Our GVWR is 13,300# and actaul weight is a right at 9000#. If I have to start stopping at the scales in Commie-forina, I will just avoid the state.

Justification at it's finest, both sides of course. I'll kick this horse again.

The reason for DRW, more capacity, simple as that. You have the same drive train other than the rear axle. Sure they beef up the springs and frame, and adjust the front rear brake balance.

As for a drw being to big for the roads, might want to look at the trucks that built the road, pave the road, gravel the road. Install the electric to the homes. Hint, all DRW.

When a 1 ton isn't big enough they build the F450, F550 or your brands equal. That isn't enough? well no problem, we can all go class 8 if we want/need to.


So that's it, if you need the weight rating you should buy a DRW. If you can axle it out with a SRW go for it. But for my fiver unless they start making super singles you can't/shouldn't try a SRW truck. My DRW barely makes the ratings on the scales and for this discussion the scales don't lie.

19.5" Rickson (or other brand) wheels & tires in load range F, G, or H *are* the "super singles" for SRW pickups..;)

Of course, they don't resemble the "super singles" used by HDTs.

Excellent alternative to/for dually pickups.
(Yikes! - Rickson even has DRW to SRW conversions!)

Yep - check the sidewalls on those F,G,H tires and do the math!

BTW - a singled class 8 HDT (good "dually" choice!) is a class 7.
