Inner Tube noob question

[aJohnson]

Ok, I have size 622 x 25 (722 x 25c) wheels, and I'm wondering what inner tube size is most advised for the wheels? I mean do I go with the same size or do I go with a size smaller?

Sorry if this is an extremely "noobish" question.

Nevermind, I think I've got it.

OK I won't bother
