Fixing a tire bead
Is there any way to fix a steel tire bead? I've got a 90's Haro that I'm fixing up, and the front tire sat so long on a flat (probably a decade or more) that the bead is kinked enough that it pops off the rim. While getting a replacement tire wouldn't be a problem, I'd like to preserve it since it's the OEM tire.

Well, you should be able to straighten out the kink fairly easily. One thing with old tires is that they develop a slick glaze on them and that can make it more difficult for the bead to grip the rim. A quick scuffing of the bead with some sandpaper might help it grip.
How much PSI are you putting in?

40, as per the sidewall. The tire is in great shape otherwise - it sat in a climate controlled basement.
How do I go about straightening the bead?

you should be able to manipulate it w your fingers
then i would pump it half way and let it sit
then deflate and slowly work back up to max psi

Just grab it and bend the bead back the other way. Bare hands should be enough to bend a tire bead back. Otherwise, hold the bead at that part of the tire onto the rim while you pump up the tire. If it's just a matter of the bead being bent, the pressure of the tire should keep it on no problem, and as long as the rubber is in good condition it should be no concern once it's aired up.

Climate controlled storage is a wierd habitat for a MTB, you should occasionally subject it to some dirt & sunlight and dont be afraid to keep it in a good state of repair with replacemnet parts as needed. Tires are an entirely expendable items. A 90s era haro is not a collectors item, it is a somewhat obsolete MTB (by current standards) that should be ridden by someone looking for a functional bike but who does not need to be on the cutting edge of technology. Seems silly to try to preserve every OEM aspect of that bike.
