Tank gear from 30-60?

[Gneo]

If you're choosing to level up via running the highest level dungeon available to you, each time you clear a dungeon you'll get a gear drop (that will be useable by your class) automatically at the end.
And of course, there's always the chance that treasure chests will drop more gear for you.
But absolutely DO spend poetics on Ironworks gear when you hit lvl 50, it will carry you all the way to lvl 60.

The free gear at the end of the dungeon is only for Lv51+ leveling dungeons. You don't get anything from ARR or endgame dungeons.

And I don't recommend keeping Ironworks gear in the Vault or Gubal Library. Maybe it's fine for DPS, but not for a tank who has to take all the damage for the party.
