Tube size

Not sure if this is a silly question!!

I replaced my inner tube tonight which was a 700x 18-25.

However I replaced it with a 700x 18/23c

Is this a bad idea? I have my A - race this sunday and don't want to spoil it for the sake of a tenner on the correct size tube?

    Well I'd imagine your tire is 700-23c, so it will be absolutely fine.

    If it's bigger than that you must be on a mountain bike!
