Yeah, I hear ya. But the tire really does need 60 psi to handle the load.
I'm not sure this would work, but it might be possible to fill the tire to - say - 40 psi, then when you need the tire fully inflated, use a can of sealant to take it the rest of the way. If I get some time, I might try that as an experiment.
And I think the reason the old tire exploded was because it was old and the rubber had deteriorated - putting to rest those folks who think unused, but old tires don't fail just due to age.
