I picked up the wheels. The fronts fit although the center hole is a shade big 1/8” all around. I may just use lug centred nuts. That should rectify that problem. Now the back inside dual contacts the drum brake outside edge. Just as was discussed earlier in the page.Ball park about 3/4” spacer should do the trick. The tires and wheels were a decent price so I feel I can play around a bit to make them work. I will update once I get the spacers built bought or any other idea I come up with. Thanks pics coming soon

You'll be better off finding the proper wheels.

Different lug nuts don't solve the mismatch in your hub and wheel center bore. Hub centered wheels (these are) it is important for them to fit snug on the hub. You could make bushings for the hubs but that's more trouble than finding the right wheels.

The interference with wheel and brake drum is a real issue too, also solved with the right wheels. Wheel spacers are generally regarded as a poor idea, I think particularly poor if attempted on hub centered dual rear wheels.

Well the best plan is always the rims that fit perfectly. Problem is I haven’t yet found the source of them. Obviously these don’t fit the bill. Other sources would be good to here. Thanks

Junk yards are probably most likely place at this point.
Obviously not all step vans but some have them.
I’ve found them on 70’s GM one ton U-Haul trucks.
Other GM 1 tons 60’s through 70’s, possibly 80’s.

No one place to look and find them. Just look for the wheels and don’t worry about what they come off of so long as they are what you need.

Good plan. Now is it possible to fit a larger rim let’s say a 22”ish. On the back . That would do wonders for the rpm at road speed. I have the 4speed no extra shift button. So the gears start low and 1st and 2nd are close together the others not so bad. So i believe the taller the tire the better . I will never have a low end power problem although I may lose power in 4th. Once I get a tach in I will have a better idea where I am. I had it at 60 mph with the original 31” tires. It wasn’t absolutely screaming. Any thoughts on this. Thanks for all the help. It’s spring here after a long winter. I’m having a ball working on and driving this old gem. Thanks

One thing to consider is that the increased leverage of larger diameter wheels and tires makes the brakes less effective. Getting it moving is only part of the problem- - - - -you also have to consider stopping and steering, which involves the same engineering that was done when selecting the original wheel size. Finding the correct tubeless wheels that match the fit and size of a tube type tire isn't just important- - - -you're betting your life on your decision. Even if you're willing to take the risk of running Rube Goldberg misfit parts, what about the rest of us who have to share the road with you? That soccer mom with a minivan full of kids in the lane next to you didn't participate in your decision to run some sort of dangerous modification!

Never even was thinking of the brakes. The brakes lock up nicely with the original tires now. Not surprising considering I have went from a grain box to a flat deck. I’m guessing the box held in the area of 150 - 200 bushels. 12000 lbs lighter should make a noticeable improvement. That being said as I remember loaded grain trucks never could stop. Of course unless loaded in the field and then one could put your head into the windshield just by letting off the throttle .... The increased size of the wheels would be multiplied drastically in stoping distance. Not to mention stress on the brake components. And not in a good way. By changing the size I have come to the conclusion that this will change the steer and brake geometry. A can of worms I do not need to open. Back to the hunt for the original size. Thanks

I have a set of 6 19.5 dually rims that are tubeless that I MIGHT be interested in selling . This is the older 50's style . Not the newer style found on step vans and such . They are kind of hard but not impossible to find. Can use a 19.5 radial from a newer step van. I had 2 19.5 single wheels . They are harder to find and sold a week after I found them. .

I was in an old yard last Friday and walked by an early 60's 1 ton dually that had the 17.5 dually tubeless singes on them. I have not seen them in a long long time.

Thanks for the thought. I may have a line on a set close to me. Thanks anyway.
