I really don't think they're related. Grease oozes out and tires come off the rim. It all happens, and more.
I've found that any good wire-bead tire works fine on these rims. And, remember, back in the 60s this kind of tire was normally operated at 65 psi, maybe 70. 105 psi was just unheard of.
I remember once when my friend and I, ca. 1962, took our bikes to the local burger joint. Before going there, we stopped at a gas station and put some air in the tires. He made his really hard, and I told him it seemed too much, No, I like them that way--his response. So we got to the burger joint, parked the bikes, went inside, and a few minutes later, KA-POW! One of his tires exploded dramatically, everyone stared, and his ego deflated along with the tire.
