I stopped by a local commercial truck tire place today wear they recap on the primacy ,they also refurbish rims ! They had some new old stock 9.00x 20" tires ,they quoted me $289 for each tire, they'll brake them down and install new flaps and tubes and put the new tire on.
They can order me this one for the same price

 

If the NOS tires aren't too old and dry their rubber will quite possibly outlast some of the new import stuff. Tubes run about $30-40 each or so. Flaps cost too. The price is not out of line. I had to pay similar money for my 20x8.25 imports and shipping was high. These bigger toys ain't cheap by any means.

 

Thank you for contacting us. You submitted the following request via alcoa.com:

Chris,

Unfortunately we do not offer any 22.5 wheel with a 6 bolt pattern. Sorry for the inconvenience. If you you have any questions let me know.

In PA it is legal to have a bias ply and a radial on the same vehicle if they are not on the same axle. I have bias plies on the front of my truck and radials on the back which I am going to replace with bias ply some day when funds permit.

 

I found some new and old tubeless 22.5 6 bud rims from $65 to 265 for new
The new ones are from accuride old stock there 6.3/4 22.5 and the used ones are 10x22.5 6 bud .
I am not familiar with big boy tire #s
Is a 10x22.5 close to a 9x 20 and will they fit my 56 ?

 

Tubeless 22.5s are a good way to go, and can be mixed with tube type on the same axle, or even teamed on the same corner, as long as both tires have the same outside diameter and same radial construction. This was common practice back when the tubeless wheels and tires first came on the market back in the '50s, and on into the '70s. Of course back then it was bias ply for both tube type and tubeless. I wouldn't be mixing radial and bias ply on the same axle though.

Those NOS Accurides will probably be their part #28157 which, like you said, is a 22.5" x 6.75" having a 6" offset and 6.5" center hole. You'll have to watch the widths of the used ones. Older 22.5s could be 5.25" or 6.00" wide as well as the presently more common 6.75" and 7.50". The narrowest 22.5" tire today is a 9R22.5 which is spec'd for the 6.75" rim, but is approved for the 6.00" rim. Guys use them on the 5.25s and say they work, but the manufacturers didn't recommend it. The 9R22.5" radial is the size equal of a 20" x 8.25" bias or radial tube type. If you go with 20" x 9.00" or 20" x 10.00" tube types you will need to get into the 10R22.5" and 11R22.5" tubeless tires to keep the same outside diameter. The 9.00" x 20"/10R22.5" pair will each be about 40.1" in outside diameter while the 10" x 20"/11R22.5" pair will each be about 41.48" outside diameter. (My reference here is a 1979 Tire and Rim Association Yearbook). If you go with the wider tires, I wouldn't go any narrower than the 6.75" rim. The 7.5" would be the manufacturer's spec'd size. This is where you should consult your tire shop before committing to a purchase.

I'd also be leary of going too wide on the front of the truck because of rubbing.

Here's the link to the Accuride catalog showing the #28157.

And here is a side-by-side of a tube type and tubeless from an old catalog showing them dualled up together on an axle. Stu

 

That's probably not all that bad a price considering I paid about $250 for my 2 new 9.00-20 Toyos. I think the recapped radials in the back were around $190 but this was about 6 years ago.
