So i have a 76 Dodge with 16.5 wheels, currently running 8.75x16.5
I would like to move to either 16's or 17's wheels since 17's now seem to be pretty common, but i'm thinking 16's might be the better of the 2
Has anyone done this wheel change? what year dually wheels fit?
would love to find some chrome take off wheels
what is a direct bolt on dually wheel?

From what I've read here Dodge and Ford 1 ton dually wheels are the same. Shouldn't be too hard to find in junk yard. Ed
Switching to a 16 inch is best. Used rims with 235-85-R16 load range E tires are easy to find in the junkyards on dually pickups. You should see if this is too tall. If so, get 215 85 r16. If you get aluminum rims, try to get the lug nuts at the same time, though they may not match your wheel studs. Chevy trucks tend to be 9/16 but M300 uses 5/8 inch. I don't know about your rig.
Watch out for the hub diameter. The Dodge uses a larger one than most of the Ford of Chevy. I bought a nice Accuride 16 inch rim, had my tire mounted, then it would not fit on the Dana 60 or 70 rear axles. It might have fit on the front, though.
You also have to watch the brake calipers, on the front, on certain setups the 16" rims won't clear the brakes. Do a search on the forum, there is lots of information on this subject. Remember the rims are coned (coined) , for the lugs, inners and outers. The problem with junk yard rims is that most of them are not straight, that is they are bent. Have them spun on a tire balancing to check them out. I found about 15 rims at the yards, but only two were good enough to use. Found a source for new rims then. New is about the same price if you have the old sand blasted and primed for painting. I put 235/85R/16E on my 78 which replaced the 8R-17.5. (Wal Mart tires Tracker II) $120 each
A 16 inch rim will clear any rim that a 16 1/2 inch will. They are, despite what you would think, about the same size.
1/2 inch sizes like 18 1/2 and 17 1/2 and probably trailer 14 1/2
use the 1/2 inch size to designate the angles tire mounting contact area and the lack of a safety bump. You can tell when a tire is a 16 1/2 in the junkyard: the tire will be falling off the rim!
Another good thing about 16's is you can get a forged or cast aluminum. Forged are seldom bent. Alco is my favorite. But of course you need a flat face steel rim for the inner, since the Alcoa is not coined (coned) at all.
Thanks guys, looks like i got a little more reading to do
Let us know what you come up with and what you end up doing.
as long as its 8 lug almost any dually rim will work.. as most were the same pattern.. as for lug nut size those are mostly the same too.. the difference is the hole for the safety nub may need to be redrilled, or the hub hole may need to be made bigger.
ford and dodge use the same hub size while those on a gm are smaller. i did find out from our ambulance mechanic that the new style for wheels, those with the small holes will not work on and older vehicle. joe said he tried to put one on one of the busses that used the wheels with the 4 holes and it hit on the caliper. he said he found that the angle of the offset is different since most of the newer ford duallys use rear disc brakes.
AHHH just found out about all this tonight and put my sources trying to find me some. Did find out from a guy on the fords I need A 97 and older to get them to work. Hope that helps a little.
I'm back at this again. It seems the more i try to find and answer the more confused i get....lol
as anyone actually completed this task. alot of folks i have talked to in the last few months...have wanted to but not done it.
the one rv i did find had alco wheels on it....but came that way when they bought the rv 2nd hand....
everyone is saying ford and dodge are the same but not sure up to what years...anyone know? do i worry that mine are coined and the new ones are not when replacing all 6?
Hi chiknnhead, i have a chevy class "c" and i changed from 8.75R16.5 to 16" of course had to change both the rims and tires on all 6. i got them from a rental box truck in the salvage yard, plenty of meat and they were good enough to get her from the previous owners home to mine.

JT, I'm assuming your Donor rims were from a chevy as well?
This topic duplicates a long running thread My bad the below is about 17.5's, the last one is 16.5's
http://www.classicwinnebagos.com/forum/index.php?topic=3391.0
This one also contains info
http://www.classicwinnebagos.com/forum/index.php?topic=5154.0
yes that is correct, they were from a chevy or gmc. I haven't done any actual driving on them yet. it was towed with them on though. it's still in the restoration stage to say the least.
JT
Just to add more info here, for the rig that i have, i need 16 inch wheels from a 93 and older dodge dually pickup
I have conflicting arguments are the start year wether it be 81 or 83.
i think i located some and going to look at them tomorrow, so i will post more info.
Fords will also work, the Chevy's have a smaller hub hole. Make sure they are cone or coined. Inners and outers. The wheels are lug centric. As I recall the bolt pattern is 8 lug with 6.5 inch. The hub hole was 4.9 inches and had a 5.35 inch off set.
Just more of a final update. i did get a set of 16 inch rims, that are the coined(con as some call it) dodge dually wheels. the wheels are date stamped april 1990. which does help confirm the 1981-1993.
I Installed new tires which where 225/75/16 which where the same height and width as the 8.75/16.5 i have on the rear axle. i went with a white letter tire they are XL (eXtra load) but not a load range D tire.
want to say thanks to everyone for their input, especially JD

Very nice indeed and very helpful as well. Great job! :)clap
I have a 74 winnie wagon dodge b 300 chassis. Not dually. When I first bought it I read ford 8 lug wheel's will work, but I bought a spare from pick n pull and it didn't fit. I thought the hub would have been the problem, but the lugs were spaced completely different. I have been looking for Chevy Truck wheels because I see a guy driving a 1 ton dodge van with 2500 HD gmc wheels. But I was told that I have 16.5 wheels because of the front disc brakes not clearing the wheels. I can't find 17 inch oem gmc wheels and I looked at that van I mentioned and they are 16. So will they fit or not?
Ypu have single rear wheels on your RV?
I would imagine Dodge van wheels up to '93 will work, and possibly Ford Econoline/F250 wheels up to '97. After these years, they switched to a metric bolt pattern that will not work.
For the 1980 Dodge chassis I got my non dually 16" rims from a small 1990 Ford E350 school bus. I think both the Ford and Dodge one ton chassis use the same rear axle (Dana 60?). I thought to go dually but I think the rear axle has to be a little wider to allow for clearance. Also a change to dually requires a different front hub to mount the drop centre wheels.
Just as a reference is case you ever want to swap axles, the ford axle, while the same Dana 60 is offset to the passenger side a few inches to mate with the engine which is also offset on Fords to give the driver more room. You would not want to use that axle in a Dodge because of compound driveshaft angles. I just wanted to add that in here because a search for "axles" may lead to it. The hubs will be the same. Brakes I am not sure.

Yes sir single wheel. .the original advertisement for it showed optional 10 in. Wide slotted mags. I wish I had those. Any how.my situation has become critical as some tweeker trash has slashed my tires and I am very broke and parked on the street. I found some 16 in dodge truck wheels from the 90s that I can afford. I really was hoping someone can tell me if the 16's will clear the disc brakes. If anyone near oakland has some spares and can let them go cheap I will be your best friend forever.
Now trying to do that exact same thing with a ford all these years later.......funny how life changes but not really...lol
Hello, I just recent bought this 1978 Dodge Brougham 18ft. I am used to 70's Dodge Tradesmans but not too familiar with RVs. I was looking into putting Slot Mags on my RV but then I started learning about coined wheels. Now the wheels that are on there now don't look coined but I haven't removed the wheels to see if the hub is coined too. This coined thing is all new to me. What are the pro and cons of doing this? I haven't seen any RV's with anything but Dully wheels so I wondering if it's even possible. Thanks for the help!
Vanner, This is a pet peeve of mine But since you are new i will explain it again ! There is no such thing as coined wheels . The proper defination is CONED ! Due to a misprint way back in the 1950,s in a Dodge service manual the I was inserted into the word ! The holes are coned like an ice cream cone . You are welcome Frank ! As far as useing 16" wheels you will have to get one with the proper coned hole spaceing , install the wheel on the veh frt and rear if it clears the caliper/drum you can use them . 16,s will cut MPG and raise speedometer readings 17,s will increase MPG and lower speedometer reading !
The aluminum wheels will have to be either lug centric or hub centric so that they do not egg out the holes. The conned holes on the steel wheels are there to retain the torque on the lug nuts and keep the wheel from moving around, it is centered on those cones. Aluminum does not have the spring to it that steel has so it cannot use that theory. You are probably best off staying with steel rims. If you plan on keeping the van for a long time then 17's would be the way to go since 16's are now on the way out like 16.5's used to be. They will be around for quite a while since they were used well into the late 90's but then the 17's started coming in. You can get 17" tires that will match the height of the ones you are running now so that the speedo will stay the same.
Thank you both for your help and info, Coned, got it. Now, the wheels on the RV right now don't look coned. I read the coned wheels would have alternating innies and outties. I was wondering if maybe some RVs with a short wheel base (18ft) and a van chassy might use plain 8 lug wheels? This is the drivers side front and this doesn't look coned to me.
I haven't taken the wheel off yet to see if the rotor/hub is coned as well. Isn't that the case where the wheel has to match up with the alternating innies and outties? Sorry, I just want to get this right before I buy newer wheels. I'd like the run 17x10 in the back and fill up the wheel well.
Those are not "CONED" lug nuts. So you may be correct (maybe).
They are a standard tapered lug nut and that area of the rim where the lugs are is raised just a bit to proved tension. The holes are well worn so you do not see the corresponding taper on the hole. No, they are not the "coned" type that we are talking about in relation to the dual wheel setups.
I think this is what coned means
I’m thinking my RV does not require coned wheels.
It does not if it has single wheels, but you have eight lug wheels which means 3/4 or 1 ton vehicle so you might not find aluminum wheels in any kind of decent price range that will stand up.
It has single wheels all the way around.

Hm?
Actually the late 70's Dodge Brougham chassis was used extensively for class B RV's, single wheel rear.
It was also used to a lesser degree for class C's in the lower length models with duals, but singles were the norm.
"coned" rims were/are indexed as are the hubs.
Vanner welcome to the site, with a name like vanner i'm sure you know of those van message boards as well...i'm on those as well
only the dually wheels were coned wheel. with that said yours with the rear with the single wheel looks odd, i'm wonder if that is rupposed to be a dual rear wheels and they switched it because your rear end looks extactly like mine. some of the rvs did come with single 8 lug front wheels and dually rear wheels, and people complained because you then had to care two spares depending on which flat you have. foot for thought anyway
Also you mentioned your was a 78, based a a few things i see your actually van body is a 77. a lot of times RV companies would order a bunch of chassis at one time, but by the time they got to some of them the next year might have already been under way. and were titled as 78's. 71-77 vans were the the same, 78 was one year only on a lot of things, then 79+ were the same. based on the fender marker lights your van is 77. 78's were rectangle and the dash on a 77 is completely different then 78.
Also welcome to the brougham club...i'm alos a member, they went out in the mid 80's. i have had mine for 13 years, this pic was taken last weekend

Looking at his picture and yours I can see your rig is wider than his, that is probably why he has singles and you have duals.
True, i wonder what that hub looks like when the wheels off, wonder if it is same rearend only with single wheel installed
It is not, the dual wheel hub is offset far out to accommodate the inner dual.
Some friends of mine had a '71 Dodge B300 Sportsman with drum brakes all around and 16.5" wheels.
Ultimately, we had to get 16" front wheels off an 80's dodge 250 series 4x4 to work up front. We then had to grind down several areas to fit over the drum, and we then welded and strengthened those areas. Had a local machinist do that work.
The rear tires we used were 16" trailer tires with a 4.77" center hub, IIRC. I switched the lug nuts out to flange nuts, and torqued them all down. It's been two years with no issues. I've checked the studs periodically for any signs of the tires "walking" and have yet to see anything that stands out.
Its a great relief for them knowing, with no spare, if they have a tire issue, they can go to nearly any tire shop, get them to put on a 235-85-16, and keep rolling.
1988 and older Ford 16" coined wheels off of F250 or F350 Van or Truck will fit. Also Dodge 8×6.5 16" will fit also as long as they are coined 1983 and earlier. You can use non coined wheels in the front by centering the wheels with acorn nuts on 3 lugs and tighten the other 3 lugs done, remove acorn nuts with lug nuts then tighten all of them down to 350ft lb.
But there is no way to use non coined wheels in the rear axle. You cannot center the wheels on the hub .
I have a 1973 Dodge B300 motorhome and I am also trying to convert to 16" rims. I found an article under Google search that states the bolt pattern for my B300 is 8 lugX5.5" bolt pattern. I cannot find these 16", 8X5.5 OEM wheels ANYWHERE and I am wondering if that 5.5" bolt pattern stated in the article is correct. I am desperate search for 16" rims for my Dodge B300.
If anyone has been successful at finding 16" rims for a 1970's Dodge B300, and can direct to the place they got them from, I would be so appreciative. I need new tires and cannot afford a full set 16.5" tires.
Livin' on a budget.
If it is a dually it is 8 lugs on 6.5" (not 5.5") bolt circle. I don't know about the singles.
