Maybe I can save some of the original tire air in a jar also...
Actually the tires have been replaced...
Dad had keystone classic rims with BFG T/A tires installed when we first got it as it had very wide Centerline rims on the rear with 50 series tires and different rims on the front with 60 series tires when we bought it from the original owner... Then later on dad bought a set of reproduction Goodyear tires and ralley rims to return it to stock look...
