So i have a strange (but neat) rear dually axle... Normally duallies stick out quite a bit, but on my truck the outer rear wheels are just as wide as the front ones, and the inner wheels are set towars the pumpkin... How does that work? special dually axle with regular dually wheels or regular single axle with special wheels? What would it take to convert to single wheels out back some day? Are there any advantages of either for offroad purposes? For now I am definitely keeping this setup, I like the dually idea since it does not stick out... What would be the metric equivalent of DRW 35x10.50 tires for 15" and 16" wheels?

is it on a truck? what year and body style is your truck? you probably have a cab and chassis (c&c) dually 14 bolt. if you search, you should be able to find threads on this topic. i think the wheels stick out slightly more than the front, even though its narrow. its a different width than single wheel rear (srw) 14 bolt. this rear still needs dually wheels, and the truck will not look right without a (drw) dual rear wheel front. to change a drw dana 60 front to a srw, or vice versa, you need to change only the hubs.

Do you mean the rear axle assembly is as wide as the front axle assembly?
Because your statement sounds like your first talking about the rear axle, then you switch to talking about the width of the dually rims, then you switch to talking about the direction of the inner rims.
I would suspect that what you have is the cab-and-chassis 14BFF.ILYA said:
The C&C 14 is the same axle width as a regular SRW one, but used dually hubs, and has the backing plate for the drums inset further.
You would need dually wheels to put dual tires on the rear ... you *could* use big spacers but that would be bad; more maintenance and more likely to come apart at innoportune times.
Other than mud I can't see any use in DRW for 'wheeling; it's useful for towing as you get greater load carrying capacity from the stiffer sidewall/narrow tire combo, which is the opposite of what you want for wheeling.
Metric tires for a 35x10.50? Hmm. That's actually awful wide for a dually; mine are 235/85-16's, which is 31.7x9.6. Anything wider wouldn't fit on more or less standard dually wheels, without spacers or custom wheels. Check out Eric M., a member here, who has all kinds of big duallies:

The tire you're talking about would be a 265/90-16, which I don't remember as being a common size, or a 35x10.50-15, same deal.
I did this on my towrig:
What I call the "stealth dually". Mine actually is a bit wider than yours, as they're SRW hubs on an SRW axle, so the WMS is +2" on each side... I coulda gone in more as I had a set of dually hubs, but it woulda been TIGHT to fit the brakes in. ('Course I ended up doing disc, but never mind.)

all right, i will take some pix in a little bit
dremu, thanx for the explanation, i think you nailed it
the truck was an old DOT vehicle with a service box and a freaking crane, i took those off and replaced them with a flatbed... the wheelbase is 135" longbed...
it has the dually wheels, can i convert to single? do i just change the hubs?
what are the differences in the hubs? can single wheels be run with drw hubs somehow?
what DRW tire size do people usually run with a 4" lift? i assumed around 35'
s... so how does that translate to DRW?

nice rig
That truck looks more like the 131.5" or 137" wheelbase versions. The 164" wheelbase is for a 4 door long bed, which is considerably longer than what the truck in the picture looks to be. It could be an illusion but I'd double check the wheelbase.
Also, when lifting this truck be sure that whatever tires you get do not rub sidewalls.

That doesn't look like a 164" wheelbase, as that's what my crewcab is (well, 164.5"). You're measuring from the center of one axle to the center of the other; at least from your pix, that looks like a single cab longbed, which is 131.5".
Yep, cab-and-chassis were sold just, well, with the cab and chassis, i.e. with no box from GM, and then various boxes were put by other manufacturers -- tool boxes, service bodies, flatbeds, etc.
You can convert to single wheels in the rear just by putting them on. They'll be a bit narrower than SRW (2" each side), but to get the wider stance you'd hafta change hubs. Changing the hubs means changing the brake drums and/or welding on new backing plates, which is work.
It *looks* like it's 4WD, yeah? If so, you can change stuff up front to make it SRW ... hubs, maybe rotors, I donno. I have no D60's (mine's a 2WD.)

ok, i cant figure out how to edit signature, but here are my rigs:
1969 KURBMASTER with 1992 GMC 454 4L80e MSD DougThorleys
1986 CHEVY K30 4x4 6.2L TH400 NP205 DANA60 DRW 4.56 FelPro
1995 CAMARO Z28 LT1 4L60e ACCEL NGK GMPP OZRacing ALDL
2000 XR600R + 1979 XR200R + 1975 MR175 Elsinore + 1986 TRX200
I guess it was my stepvan that had a 164" wheelbase same as crew cab
This truck is actually 135.5" or so
So, if I just put on single rear wheels onto the hubs that I have now, they will be 2" narrower than the front?
Yes, it is D60 up fornt... what do you mean "you can change stuff up front to make it SRW"??? is my front end somehow different because it is has dual rear wheels?

The rear WMS is 4" less than an SRW axle. What the rear is as compared to the front depends on what you do to the front...
Well, yeah ... look at it. The mounting surface for the wheels is OUTSIDE the tire, made for dually wheels ... if you put regular wheels on it the tire will scoot out a coupla inches, which'll screw your steering up something fierce.
Or you can use the dually wheels up front and whatever else in back, which means carrying two spares.

your front axle currently has a set of dually hubs on it. You can convert it to SRW hubs. its very easy. buy a set of hubs and bolt them in place of what you currently have now.
want a headache? read this. It's everything you need to know and then some.

yeah, changing hubs is more than i need to get involved in right now...
what are the biggest tires that i can fit on these rims? are there wider dually rims maybe that i could use? i am thinking about lifting it about 4" or so... but on the really cheap side, so no changing hubs or anything

To keep the rear tires from rubbing on each other I would go with a tall narrow tire, like a 35-10.5-16. Interco makes boggers and probably also swampers in this size. I think BFG has tires in this range also. Interco also makes a 34-10.5-16 LTB, which would work with a 4" lift.
well, 35-10.50 was the size i was originally after, but now i am not too sure... what width do you guys think these wheels are and what are the narrowest wheels that 35-10.50 tires will fit on? the 235-85-R16 tire size that i have on right now converts to about 32-9.25...
Those OE dually wheels are 6" wide. The dually spacing (offset) is also quite narrow. I believe they are only intended for 215/85R16 or 7.50x16 tires.
Newer dually wheels - and Fords especially - can take 225 or 235 series rubber since they have more dually spacing.
If you can get your hands on 9.00R16 rubber (i.e. Michelin XL) they should work well on duals.

Even when bulging from a heavy load?
Michelin 9.00R16s are 36" tall new. They are a very chunky tread, but are recappable. Supposing you found some cheap with minimal tread, you could have them re-capped with a more pavement-freindly tread.
so after a few minutes of reading, those LZT tires do seem pretty nice... and recappable, thats good... and seems that a 9.00-16 size fits this application... would they fit with just a 4" lift? those 9.00-16 seem to be about 36" tall by 10" wide, so would 35x10.50 be that much different? is there a metric (or other) equivalent of these tall skinny tires, just to keep my options open...
as far as 235-85-16's = look at this picture - without a load in the bed:
