Are you using the tires for display only or for riding purposes?
Also, are you referring to tires that glue on wood or metal clad over wood rims? Those tires are marked 24 x 1-1/2
I have a pair of old " York " 24 x 1-1/2 inch with a nice tread pattern and have filled them up Sunday, but will wait till about Wednesday to see if they still hold air. (they used to) They do have some side cracking though, but that never interfered with holding air at that time. They also glue on the rims.
