I know this topic gets brought up all the time but I it appears to me that I have the dreaded RH5 wheels on my truck. Is that correct?

Front Wheel
Rear 1
Rear 2

Also are the front wheels (9-22.5 rubber) and the rear wheels (8.25-20 rubber) the same?

Finally, I have read through the Big Bolt Tech Tire Tips and it mentions that Accuride has a 5 and 10 hole wheel that might work for the AD trucks but what about new wheels for 6 hole pattern like this truck has?

Sorry for all the noob questions but I just recently got this truck to my house and am pretty excited to get working on this and budgeting for all the different parts and pieces.

The front are tubeless type wheels. They are great. The rear are the dreaded split type. Very dangeruse. They are the double lug Budd wheels. You can find them used with the lock ring type mounting which are not as hazardas as the split rim.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.

Hy DougH6100, it appears your rear wheels are the dreaded RH5s, but you are lucky you already have two 22.5" tubeless wheels on the front. So you only have to find five more tubeless wheels (one for a spare). I am not sure if anyone is still producing new six stud 22.5" wheels, but you should be able to locate some more of them, they do come in different widths so determine what size tires you are going to run before you look for wheels that way you'll know what width of wheel you're looking for, hope that helps.

Doug,

The 6-lug 22.5 tubeless Budd wheels were used on school buses into the 1970's, so start looking at the old buses in your local junk yards.

The 9x22.5 tubeless tire is the equalivalant to the 8.25x20 tube type. If you put 10x22.5's on the rear you'll get a little more top speed as they are taller.

Thanks for the replys guys.

Does anyone have a link explaining the old tire sizes? What do the different numbers stand for?

Also would a lock big truck tire shop know what these numbers mean? If not where is a good place online to look?

I agree that the front wheel pictured is a 22.5" wheel.
Also that the rear wheel pictured is an RH5 20"

The "old tire sizes" are still in use today. for example 8.25x20 and 9R22.5
22.5 or 20 is the rim diameter at the bead seat.
The R indicates radial, and X or - is usually bias ply or could be unspecified depending on where/how it is used.
8.25 or 9 is the nominal tire width at the road, not always same as what you might measure... use more for comparison between sizes. For actual width look up the exact tire specs for that model tire from the tire manufacturer.
The rims they fit on will be somewhat narrower than the tire size. For example a 9R22.5 tire should fit on a 6", 6.75" or 7.5" wide rim (measured at the bead seat).

More info here, page 47 and 48 among others:

Bumping an old tire thread of mine. Finally got the front wheels off my truck. I'm no tire expert but I believe these are steel one piece rims. Am I correct in that statement? Thanks

Those are one piece, 22.5's, which are safe to use if not rusted too much.

Count yourself lucky as most guys are stuck with 20" tube type RH-5 widow makers...you struck gold with the 22.5" tubeless rims!

Are your tires 9.00x22.5 or 10.00x22.5?

Well I feel like I won the lottery but it was in a an office pool. The two front wheels are the steel rims and they are wrapped with 9x22.5 rubber, both are bald and one has a nail in it. The back four wheels are the RH5. So I was please to find that my wheel budget was decreased by 1/3.

If Doug struck gold with his two 22.5" one piece wheels then I must have died and gone to heaven, All seven on my truck are one piece and all hold air. I'm still trying to decide on how to get them blasted and painted but not have the truck laid up. I found 4 Michelin radials on Craigs List at $75 each, in great shape, I feel luky.

Be happy you're not looking for the 5/10 lug 22.5's...the 6-lug are WAY easier to find AND cheaper!

Be safe around the RH-5's...if they are low on air, do not add air...the safest thing to do is to let all of the air out and just roll around on the stiff sidewalls.

Be aware of build date on radial tires, they are not known to last as long as bias ply tires.

Again bumping an older thread of mine to keep it all together.

Finally got all the wheels off the big rig and found quite the mix of rims. 2 one piece tubeless, 2 RH-5's and 1 each of the rims in the album below.

Question is about these two. They were the inner wheels on the rear, RH-5's were on the outside. They look like multi piece rims. If not rusted too much would these be safe to sell or should I scrap them with the RH-5s? The plan is to put all new rims and rubber on the way around.
