Answer
Mike,

This is a very, very old type of tire and the only places you can get these are from people who make vintage tires - like Coker Tire.  But I should warn you, they prices are not going to be pleasing.

But if you want a modern equivalent - the problem is that in the meantime, tires have gone tubeless, and those are tube type - and that means the rim doesn't seal.  For practical purposes, you won't find tubetype tires except from vintage sources

So you need to figure out if you can switch axles, or wheels, are some other way around the problem.
