Each rider has their own definition of acceptable "trueness." This includes side to side and up/down variation. For some, it has to be within fractions of a mm, while for others, if they can't feel it and the brakes don't rub, then no worries. None of this depends on your rims/hbs/spokes/spoke pattern. Your call.

less than .3 mm out of round and true. I've also measured tires and I find that even high quality clinchers are out-of-round by at least 1 mm. In a perfect world, wheels would be perfectly tensioned and perfectly true, but in the real world there is a trade off between perfectly tensioned and perfectly true. I will ride any wheel if I can't feel a problem. That usually means 3 or 4 mm out of true and 2 mm or more out of round.
