Thanks I figured 5/8" was iffy.
3/4 is okay though? I think I'm just doing basic 12" or 13" square porcelain tile. nothing crazy.

Remember I am also sistering the joists which theoretically effectively reduces my spacing to 14.5". I'm not sure if that happens in practice though since the new joists will never line up exactly with the height of the old ones.
