The wheel in your photo IS NOT an RH-5. It's a 3 piece wheel, consisting of a barrel section with the center and the bolt holes, a full circle outer bead ring, and a split ring that locks everything together. It's perfectly safe to run "as is"- - - -there's no need to look for different wheels unless you want the convenience of running 22.5" tubeless tires. How about the front wheels? Do they have a flat raised area about 2" wide out by the barrel part of the wheel? That's the simplest way to identify the illegal and dangerous RH-5's. Because of the way the front wheel isinstalled, you'll need to look INSIDE the wheel to see that raised lip if it's the "widowmaker".
It seems that I'm just full of misinformation today- - - - -when I enlarged the pic of the rear wheel, it is indeed a RH-5 design. Those wheels will need to be changed, either to 22.5" tubeless, or the 3-piece 20" wheels I mentioned above. Sorry for leading you astray! Jerry

Your rear axle appears to be from a 2 ton or larger, my '57 2 ton has that bolt pattern with 22.5 Budds. Fronts and rears are the same on 2 ton and larger.
1957 Chevrolet 5700 LCF 283 SM420 single speed rear, 1955 IH 300U T/A, 1978 Corvette 350 auto, 1978 Yamaha DT175, 1999 Harley Davidson Softail Fat Boy
Starting in 1956 ALL Chevrolet 2-ton and larger trucks with Budd wheels were 6-lug on 8.75" circle. After 1955-2 only the 4000 series trucks had the 5/10 lug rims. if you got the optional 2-speed 15K pound rear the lug pattern still stayed the same.

What year did they change back to the 5/10 bolt pattern? All of the 67-72 medium duty trucks I have seen but one were 5/10. Only seen 1 with the 6 lug pattern and the rest were daytons.

I should have said 6000/60 series trucks had the 6-lug at least through the TF series.
I do know the 5/10 lug were used into at least the early 1970's on the 40 and some 50 series trucks (some 50 series trucks in the late 60's used the 6-lug), but the 60 series and up used the bigger bolt circle 10 lug or Daytons.
