    I've dug through the old threads, just looking to see if anybody has put any other brand of 8 x 6.5 dually wheels on an OBS truck. I feel like the correct Alcoa dually wheels for these trucks are getting as rare as hens teeth, but there are lots of newer Chevy and/or Dodge wheels out there that are both plentiful and newer in physical age.

    Again, I'm not particular about style as I really would prefer a stock steel 17" wheel, but I'd be open to the aluminum front/outer rear wheels as well. Again, my goal is to get to a 17" tire.

    Lastly, I know the hub centric center opening size, and the 1998-newer Ford dually wheels have metric patterns that won't work. So I guess I'm really asking: has anybody put Chevy or Dodge dually wheels on an OBS truck, and if you did, what did you have to do to make them work?

    Sorry for the confusing post, and I'm guessing I may not get any response, but I'm just trying to figure this out before buying a set of wheels.

    A friend of mine put newer Dodge 17" alloy wheels on his 92. Chevy or Dodge wheels both need the center hub bored out to fit the Fords. That's all he did was bore the center.

    If boring wheels presents a problem, Ford hubs can likely be turned down the 10-12 thou' or so to fit later Dodge wheels.

    Can't take this route for GM wheels though... turning ~1/4" off the hub is cutting into your axle bolts.

    As others mentioned, boring the centers or turning the hubs are your only realistic options if you're looking at running other manufacturers stock wheels. Though this is really the kind of thing you'd want done on a lathe, as just hogging out the center bore by hand is potentially going to cause some major headaches in the wheel centering and balancing department.

    As our hubs/wheels are hub-centric, you really want that center bore to be perfectly round and on center. Even if they were lug centric, you'll play hell trying to find a tire shop that will balance them correctly with a hogged out center bore, as I did when I opened a set of Dodge 5 lug 17s to fit on my Samurai, with a plasma cutter. The center bore was anything but round afterwards. But then I couldn't find a single tire shop in my area that knew how to use lug centric adapters on the balancing machine....or they just didn't want to, and acted like they didn't know how...I just ran balance beads in them for a while, and now those wheels/tires are my end tables in the living room :D

    That said, if you went aftermarket, there's plenty of options there, or you could have some place like Stockton wheel custom make damn near whatever you want. Of course, both options are going to be expensive.

    Thanks for the creative thought of machining the hub to match the wheels. I can honestly say I never thought of that. It reminds me of the first time I saw somebody turn a diameter down pm a vertical milling machine with the part in the drill chuck and a cutting tool in the Kurt vise. All depends on your perspective.

    My only reservation with this is if I ever decided to go back to stock Ford wheels, the hub wouldn't be there to line up the wheels. I didn't want to be married to any one set of wheels, but then again: I'm commitment phobic (ask my wife).

    I guess you'd be ma
    I guess that you'd be machining out the wheels then? This is why I stick to OEM Ford or aftermarket. FAR fewer headahces. I left a facebook Bull Nose page because at least once a week some one who didn't want to do any reasearch was asking "how big of tires can I run on my truck without a lift?" There was always plenty of answers without any idea on what it was. 100? 150? 250? 350? 4X4? 4X2? The next most asked question was "will this Dodge/Chevy part fit on my truck?" Usually about wheels. I'd usually tell the not to run Dodge/Chevy crap and ruin their trucks.

    I run 17” dodge wheels on my idit with 265/70/17, work fine but I had to grind to get the hub/axle to clear the wheel not a lot but couldn’t machine it, works fine
