Running an Alcoa 22.5 and a stock 16" wheel as a dually setup?

[NotStock]

There is a company that claims to be doing this succesfully and I wanted ya'lls opinion about it. This is for the rear of a dually. They are running a stock steel 16" inner wheel, then an adapter and a 22.5 that has been milled down to a 22. Running tires that match OD. I like the idea and it would save some money on tires and keep a decent payload. What do you all think?

 

[ChattyCathy]

I dont like it.

My conern is the 22" tire. Obviously the sidewall flex of the 16" tire will be much more and thus create an unequal load between the two. The alcoa wont ever fail so that puts the weak link on the tire. I dunno...

What I had planned on doing was running a milled down super single out back and a normall alcoa up front. Turns out, no tire company offers a 15"+ wide tire with an OD of 34" +-. Currently, I have ten 22.5 and 2 super singles sitting at my shop waiting for me to figure something out. Its driving me nuts!

Put the whole shebang on Craigslist and go with some 19.5 "G's"

Im kinda sold on the look of the 22.5/22" Alcoa's. Your right in that being the "most practical" route, but we all know how looks can get the better of us.

its a horrible idea, seriously you should just send them to me and i will take them off your hands..... if that doesnt work, i guess i can just give you my opinion.... my thinking would be that it might be ok if you ran it on a 22 and not a 22.5 the 22 inch tires as i understand it would be more like a "normal" tire so the stresses on the tires should be closer to the same than the 12 ply or whatever "commercial" tire is i may be completely wrong i just remember that comming up whenever i was talking about doing the same thing... also would the tires ever truly be the same diameter? i mean i know how you can have 5 diffrent tires from 5 diffrent companies all in the same size but the TRUE heigth of the tire when mounted on the rim and properly inflated will be different. so it would be hard to get 2 dif. sizes of tires to be the same diameter loaded or unloaded

Im certainly not going to be running a 22.5 tire. They are 3x as heavy, ride like bricks, and have a load capacity far beyond anything the truck could ever handle. The sizes wont ever be exact but, they will be pretty close, within a couple thousands. Again, Im just looking for other peoples thoughts.

 

[Lowdown89]

Oh I know that was just one take on the situation that was talked about when my buddy was wanting to do the same thing, i mean as long as they are close as possible and you aren't ever carrying huge loads I don't see a problem with it, I'm sure people who use their truck everyday to haul the max possible might see issues but those are the only ones... While I like having things done right I'm super cheap whenever possible and I would prob run something like that if I get the money cause damn I want a set on my dually lol

I know a guy with a dodge that had the 22.5 wheels turned down at a machine shop and runs 22's with no problem. When he first mentioned it I was skeptical but there seemed to be plenty of material, and you only need to take 1/4 give or take off to make it work.

But the question here isn't in turning a 22.5 into a 22, but in then pairing that tire with a 16" wheel/tire combo on the same hub right next to it with a matching tire OD and whether or not the two tires will act in unison, or place unequal load on one or the other.

Correct!! 22.5 and 24.5 are turned down everyday without issues. Its the tire pairing Im concerned with. From the research I have been doing it looks like guys are running a 305/40R22 outer and a 235/85R16 inner.

Another question, I found a narrower version of the super single which is 12.5" wide compared to the normal 14" wide (which is what I already have). Yokohama offers a 13.2" wide tire. Could this be run safely on a 12.5" wide wheel?

 

[jimdawg185]

I was just making a statement, I didn't mean to derail or anything. I have seen a couple of trucks doing what you are talking about, so it must not be all that bad (unless those trucks were driven by morons, which is possible in central VA). I'm interested in where you go with this.

If it were me I'd just run 22.5's (or22"s) all the way around, rather than put 16's on the inside of the rear.

I'm confused are you trying to decide whether or not to run 4 tires and wheels with super singles, or 6 dual rims with 22's and 16's as inners?
I don't see why a 13.2" tire would be a problem on a 12.5" wheel either. There's A LOT of guys running 12.5" wide tires on the 8" wide factory dually rims.

I will probably end up running all tires/wheels the same. I just had never heard of running two different combo's until I talked to a shop that does it commonly, at least according to them.

Orginally I wanted to run a super single in the back but found no tires to have the needed width to run on a normal super single (normal super single rim width is 14"). Then after doing more research, I came across a for sale ad with a set of 12.5" wide super singles that I had never heard of before. Therefore the though of running a super single in the back again became a possibility. Still dont know what route I may go at this point though.

I see, well my vote goes for 6 22" classic alcoas with some nice tread to wrap them in.
Also, if you do super singles in the rear your limited to only commercial tires I believe?

Regaurdless of what rim I run, Im gonna mill them down to a 22". That way I can run normal automotive tires. Better ride and ALOT lighter.

 

[Cobra 19 & 54]

The mismatch is a bad idea IMO! Wait a little longer and get the full set.

 

[NotStock]

I have 10 normal 22.5's and 2 super singles. So the problem isnt not having them. I like the increased load capacity that running an r16 10 ply tire presents. The truck is our shop truck so it tows trailers and hauls quite regularly.

 

[Vader's Fury]

I know this is an old thread, but I am wondering what you finally decided to go with?

I am looking at putting super singles under my new(to me) F-450 and have been looking to see how others have done it.

 

[NotStock]

I never found a tire with a short enough side wall and high enough load rating to do it. I opted for shaved down 22.5's and some Toyos.
