Take a look at the tech tip here, http://www.stovebolt.com/techtips/wheels/Your asking for problems trying to use them. | | | | | Joined: Nov 2010 Posts: 1,159 Shop Shark | | Shop Shark Joined: Nov 2010 Posts: 1,159 | Welcome Vegas6400! PLEASE follow Don's advice! These things are called "Widow-Makers",for a GOOD reason. We want to see the results of your restoration,not the results of a tire explosion! I don't believe that any reputable truck-tire shop,will even consider working on those rims! Insurance probably wouldn't cover the liability! | | | | | Joined: Jul 2008 Posts: 413 Shop Shark | | Shop Shark Joined: Jul 2008 Posts: 413 | Dont Do It!!!

It looks to me like someone cut the centers out of a tube type wheel, and welded them into what looks like drop center tubless type wheels. What size tires fit on those wheels? | | | | | Joined: Apr 2001 Posts: 199 Shop Shark | | Shop Shark Joined: Apr 2001 Posts: 199 | I thought the same thing too. He is referencing 22.5 tires.... | | | | | Joined: Aug 2009 Posts: 184 Wrench Fetcher | | Wrench Fetcher Joined: Aug 2009 Posts: 184 | If they split in the middle(think oreo cookie) they are the RH5 and SHOULD NOT BE USED. They are a bad design that only lasted for a short time and with time rust has made it a horrible design.
Your rims(at least some of them) have a drop center for a radial tubeless tire, they are not RH5 or widowmaker. It is not the tube tires that are bad...or even a multi-part rim that is bad, but the specific RH5 design.
If your rims are non-factory fabricated I would look at them really carefully before painting for any cracking that may be present. It may even be worth getting them magafluxed. There was someone a while back who had a wheel company weld in old centers in a new rim and after a few years had some nasty cracks develop....looked to be bad welding. Before painting is the time to find any issues and fix them.

You gotta give us some more info here or this thread is going to turn into a RH5 safety lecture. | | | | | Joined: Jan 2013 Posts: 603 Shop Shark | | Shop Shark Joined: Jan 2013 Posts: 603 | I have the RH5* on my 58 GMC 370. Those do not look like mine. You can see the weld all way around, that is not factory on the RH5*.

Then I figured that in the car and truck world people fix billet rims by cutting the centers out and re-welding them into new hoops and for the classic / muscle car group people take original centers and put them in wider rims to fit wider tires. So take the same concept as that and apply it to the larger trucks. I call around and find a few companies that say this process is part of their normal routine, so I remove the genuine Firestone RH-5 centers and drop them off to a shop. Well it comes to it most of the places that I went to came up with the conclusion that rims in a 22.5" size are unavailable. So I ended up searching and tracked down some 22.5" rims that would work a 8.25 and 11.75, a 7.5 was really prefered but I was unable to locate any new ones. Shortly after a pallet of wheels arrived, I did some test fitting and the sizes were pretty close, tried to get them pressed in locally and they were slightly too big. Ok, that's not a problem chuck them up on the mill and shave them down to size, well it appears that they are slightly too big for what I have, go around and look for a local machine shop that has a large lathe, and no one has one to swing these. Well it's back to the wheel shops, guess what, none of them had a large lathe either. After almost 2 years in the making, much expenses, and travel all over I have a set of partially completed tubeless rims. Still needs finishing coating, and some rubber.

I think for my green truck, if a wide track rear axle can be located a set of four 8.25" wheels will be used with 315 tires and just flipped around to save on costs, plus the 385 seems a little over kill, but was needed to gain a wider stance with a narrow axle. | | | | | Joined: Mar 2009 Posts: 186 Shop Shark | | Shop Shark Joined: Mar 2009 Posts: 186 | Very nice I did something similar last year but I wanted to still run old school tube tires so I got 1 piece drop centers from Coker 4.5" rims removed my old centers and welded them into the new blank... Like you said seemed easy in concept... I too had to turn down the centers, I didn't have acces to a lathe big enough either... I went with a rotary table on a bridge port ... Here's my process it's funny how similar we went about it.. https://www.stovebolt.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=725349&page=1

I know there are 7.5x22.5 dayton rims available You may have more work involved though if you had to remove the flange for the wheel spacer. Tad

Did you proceed with painting your wheels, if so was the tire install easily done without any damage. I've installed standard tires without much issue, but these commercial tires seem to be a beast in weight and stiffness. I would prefer to powder coat, but it's not easy to find good people around here. It's great to hear that you were able to cut them down yourself, especially with short travel Bridgeport. I threw one of the rear wheels on the mill today to enlarge the center bore, and well some longer studs were needed to clamp these wheels, just have to wait until they come in. http://farm8.staticflickr.com/7282/9245402942_775035f8dd_z.jpgI agree with you, this is not complicated by any means, you would think that some of the places dealing with wheels all day long would be on hand to offer such services and be knowledgeable in their field. I can definitely see how people could be discouraged or given up on this. Glad to hear this is not an isolated situation. | | | | | Joined: Mar 2009 Posts: 186 Shop Shark | | Shop Shark Joined: Mar 2009 Posts: 186 | The centers are from my 36, that style can also be found on 34's and 35's but the center bore is smaller on those Those are some massive rims you got there! I painted my rims, mounted them without any problems.. I used some of that harder paint you can get from Eastwood http://i385.photobucket.com/albums/...2C6-233-0000001894FA5DCE_zps5edadfcd.jpgKeep up the good work!

Laying about 5 feet of bead got kind of tedious. I slowed down my wire speed a little to make a nicer bead and still got plenty of penetration. | | |
