Is There A Formula...

...for figuring the difference between the rim size of a side-ring wheel and a drop-center rim?

I ask this because I know that a 20" side-ring rim can be replaced almost perfectly with a 22.5" drop-center rim. I have possession of my dad's old 3/4-ton International pickup that has 16" side-ring wheels, and I'd like to replace them with drop-center rims. Problem is, these are the 6-lug-on 7-1/4" bolt circle wheels, so I was considering the idea of looking for a specialty shop--such as Stockton Wheel, for example--that might remove the centers from the wheels and weld them to new outer drop-center rims.

NO, I'm NOT stupid enough to try that at home.

But if I could find a shop that would do that for these hard-to-find bolt-circle wheels, the old truck might be able to live on. Many shops won't touch a side-ring wheel, probably because of the horror stories still being told about the old "widow-maker" split rims; Plus, the idea of running tubeless tires is something I find appealing.

Thanks in advance for any helpful replies.
 
It is not hard to find rims to fit those old IH trucks. There are several of them around here and the guys have more modern rims on them.

I would check with Mutual Wheel. The have stores all over the mid west. If you know what size tire you want to use and the bolt pattern they can find you a rim to fit.

Then there is no need to "make" the rims for it.
 
I wouldn't worry about getting the same size or a formula. Tubeless tires come in so many different sizes you shouldn't have any trouble.
 
If you are converting to 22 radials, there should be plenty of rims available cheaper than remaking yours. They are still being made new, in addition to many used out there.

Your rims should be worth $50 or so to folks who have good bias 20 inch tires, but need to replace the widow maker style rims that no longer can be serviced in most areas. Makes the 20 inch getting to be a bit rare.

This truck has 16" wheels...hoping that maybe a drop-center 18" might fit the centers. I've seen some nice looking 18" truck tires on newer trucks, so I'm hoping that's an option.
 
Oh. Got thrown off with your mention of 20 inch rims, sorry.

I likely have the same split ring rims on dads old junk pickup sitting here.
