will the 22.5s work on a work truck with tubeless tires and what size?

 

What size is the rim? 5.25", 6.00", or 6.75"? Do you have the 19.5" in a 19.5" X 6"? I would like to find 7 so I could have a spare. I plan to use this truck to work on the farm. I'm a little confused about the wheel thing, but would like to keep about the same ride height.

 

Chris. Ive got a couple sets. Ill pm you.

The tubless wheels will fit an 9R 22.5 tire.

 

I have some 22.5" in the 5.25" and the 6" width. I also think I have one or two in a wider width but haven't dismounted those tires yet to see.
(I've got at least 4 complete sets of 6 22.5" wheels.) one set has six highway tread tires in good shape just older, two sets of just wheels, and the set of 4 good Seiberling traction treads on wheels (pics below)


I've got 6 of the 5.25 size (I think) 19.5" wheels Stu, Truckdog on here also has a set or two of those 19.5"s that he would sell you. he knows more about these wheels and tires than anyone I know, and everything I think I know about them I learned from him. (Thanks Stu for everything)

Thinking back from what Stu has said in the past I believe the 5.25" width 22.5 wheel is spec'ed for a 8R-22.5 tire however I don't think you can buy a new 8R tire anymore? 9R tires are available and some guys have used them and say they are fine, (might have a slight bit more crown in the tread of the tire) if I am remembering correctly?

I have a 8 NOS Goodyears 8R-22.5 tires from an old Uhaul business that closed up shop, the tires are probably from the 80's or 90's? they were stored in the wharehouse all this time. (pics below)

anyway as you can see I have a few options.

let me know if I can help

What I know is this. The 22.5" x 5.25" tubeless wheels that I have record of are Budd #69930 which has 4 13/16" of center disc positive offset, Kelsey-Hayes #40159 (Ford #TDAV 1015-C) which has 4.81" of center disc positive offset, and Motor Wheel Corporation #84829 that has 4.75" of center disc positive offset. I find no record of Accu-ride (later just Accuride) having made a 22.5" x 5.25" having the 5 x 8" pattern.

My Tire and Rim Association references show that a 22.5" x 5.25" wheel has a "design" tire width of 7", but is also approved for an 8" tire on the wide side. A 22.5" x 6.00" wheel has a design tire width of 8", but is also approved for a 7" tire on the narrow side or 9" tire on the wide side. A 22.5" x 6.75" wheel has a design width of 9", but is approved for an 8" on the narrow side or 10" on the wide side.

A different page in the Tire and Rim Association reference says that a 7-22.5"/7R22.5" tire requires 8" of dual spacing. An 8-22.5"/8R22.5" requires 9.2" of dual spacing, and a 9-22.5"/9R22.5" requires 10.3" of dual spacing. Dual spacing is twice the amount of positive offset shown for each wheel. Stands to reason that two wheels mounted together as a dually yield double the positive offset of each similar wheel.

This is why a 22.5" x 5.25" wheel is not approved for the narrowest tire presently available, a 9R22.5". Double any of the cited 5.25" wheel offset figures above and you fall well short of 10.3". We know that rubbing of sidewalls spells rapid destruction of a set of tires, and when loaded sidewalls (especially radials) do flex. I know that we've heard from guys who have had luck using 9" tires on 5.25" rims, but I suspect these saw mostly parade duty or were otherwise not loaded.

The tires Josh has pictured are NOS (or nearly so) 8-22.5" bias ply, not radials. These are ideal, imho, for use with 5.25" wheels on a period correct truck. The use of older tires is also, I realize, of concern to some. But personally I'd rather use older US made tires on my truck than new imports. Matter of fact, that's what I have on my truck with several NOS sets in reserve under tarps. Stu

 

I would like to replace all the tires and wheels I have now. What I have, has no tread left I'm ok with NOS, but want shed of the widow makers. I will be using this as a practical work truck. HELP ME decide, I yield to your expertise, Stu. Let me know about cost and shipping.

I believe this quoted section rules out 5.25" rims. If Josh or others have a set of used 6.00" or 6.75" wheels they, when teamed with 9R22.5s, will be the match for your 8.25" x 20" widow makers. In my email to you earlier, however, I added reference to the fact that original 22.5" wheels, in all but one instance, were not designed nor intended for use with radial tires. Again, on a truck used commercially this is a factor to consider. I've only heard of one set of that radially approved wheel, Accuride #27759, having been found.

An option I haven't described yet is a set of factory brand new wheels, 22.5" x 6.75". I learned recently that Chuck Mantiglia of Chuck's Trucks has available new Accurides having the 5 lug x 8" pattern. These are the best of all worlds for a truck being used as originally intended. They will understandably be more costly. Below is a link to Chuck's web site.

On the other end of your cost spectrum are the 19.5s. Both the 5.25" x 19.5" (Budd #72070) and 6.00" x 19.5" (Budd #89340) use 8R19.5" tires. The 6.00" was radially approved but I don't believe the 5.25" was rated at all, being older, because it predates the existence of radials. Josh and I, and perhaps others, have sets available. You have our emails and can check the classifieds for others. Stu

 

Excellent thread with some great info on wheels! Thanks guys for taking the time to share your knowledge and expertise.

Spoke with Juan at American Wheel Specialists today; he has both 19.5 and 22.5 wheels in stock for the 5X8 pattern. Prices he quoted me were $259.00 for the 19.5's, $287.00 for the 22.5's. I told him I was in Portland and he did not say I had to, or that I could, go through Les Schwab. When I went by Les Schwab last week and asked about 19.5's on 5X8 pattern, I got the response that they didn't know where to get them and had no stock number, even after I told them that American Wheel Specialists supplies them to them, according to my info.
An update on Stockton Wheel:
My back and forth e-mails with their sales department indicates that they don't carry anything in 5X8; they also told me that they could not use my 20" centers to build either a 19.5" or a 22.5" because of the differences in rim sizes from the original. Frankly, it didn't make much sense to me what I was being told, but that is the gist of it.

The salvage yard down the road has many 20" split ring wheels on old trucks, laying around, stacked up, etc.

 

I just called and had a nice conversation with Juan Murillo to update myself on any changes that may have occurred since my visit of a few years ago. Nothing major seems to have changed. They do still have wholesale relationships with Les Schwab and Commercial Tire. And I learn with Discount Tire and Tire Factory. The new 22.5" x 6.75" wheels mentioned above by Mark are similar in appearance to the 19.5s pictured in this thread. They have a wider face than the old wheels to accommodate disc brake calipers. He said they do now also have a reliable supplier of bare 22.5" x 6.75" outer rims to mate to old widow maker centers. The cost would in most cases be similar to the cited cost of new wheels. He will text me a picture of the new 22.5" tomorrow and I'll update this then.

The salesman at Schwab wasn't well schooled. Juan also confirmed that there should be no shipping charges on wheels since trucks are traveling back and forth anyway. Stu

 

Thanks Stu; I hadn't asked Juan about the relationship with Les Schwab, it occurred to me afterward that he hadn't mentioned them during the conversation and he had asked me where I live. Perhaps he thought I was aware of the Les Schwab connection so didn't think it was needed. He did ask where I had heard of his shop and I told him about all the great people who provide a wealth of info right here at FTE. I also had neglected to ask about having my centers used to make 22.5's; that was actually what I was looking into but it slipped my mind. Juan is really friendly and comes across as very knowledgeable.
The Les Schwab I went to and asked about wheels is the same one I have been going to about the company vehicles I have been taking care of and I spoke with the manager about the wheels. He told me there was no such wheel in his computer and asked if I had a stock number or the phone number for American Wheel Specialists but I didn't have the number with me. I told him he could look it up however I suppose he didn't.

 

Was there any outcome as to whether the original WM centres can be fitted to new 22.5 hoops?

 

The limiting factor originally was inconsistent availability of narrow 22.5" x 6.75" outer rims. I spoke with Sean a few weeks ago and reconfirmed they now have a reliable source. The widow maker centers fit the 22.5" rim snugly along the rim's drop center.

I must assume the factory new outer rims, like the new complete wheels discussed in this thread, are imported from Turkey. Seems a wheel company in Great Britian could obtain a set of rims for you and remount the centers locally.

Your mention, however, of a need for low profile tires will require you to investigate whether modern metric sizes are shorter in diameter than the more commonly recommended 9R22.5" size. The 9R22.5" is about 38" tall which equates to an 8.25" x 20" tube type. It might also be that the 7" and 8" wide varieties of 22.5s are available in GB or in Europe. I've seen mention that they are still produced in China but not imported into the USA. Stu

 

Thanks,

Yes, 22.5" truck tyres are commonly available here in the UK.

Did you find out if the re-mounting of the current wheel centre could be off set sufficiently to allow face to face mounting for the rear duallys?

I was also thinking about choosing a really wide 22.5" rim for the rear, so I could do away with duallys and just run a single wide tyre at the rear, or is that a dumb idea?

I think the key for the front is to find the narrowest and lowest profile 22.5 tyre I can find, then choose a rim from there. A wider rim can always be narrowed. Id never band one wider due to the loads, but narrowing one shouldn't be a problem should it?

Also, has anyone re-drilled or machined the drums for a different lug pattern to open up the wheel possibilities? Or are adapters ever used?
