Tube size for Pacenti SL23 rims and 23c, 25c tires

I just ordered a new wheelset based on SL23 rims, which of course are quite wide at 24mm. We all know that moving the same tire from ~19mm to 23-24mm rims makes the tire volume increase. But does it increase enough that I need to use larger-volume tubes? For example the standard Conti tube size I have always used with my 19mm rims on either 23c or 25c tires is rated for 18-25c. If I put 25c tires on my wide SL23 rims, can I use the same tube size, or should I go up a size to the tubes rated for 25-32c? Thanks!
