Overlapping sizes on inner tubes?

I have got 25c tyres on and they make "Continental Race" inner tubes in a 20-25c and then a 25-32c.
Both will fit, with one being at the limit of how big it can go (20-25) and the other at the limit of how small it can go (25-32).
The 25-32 ones are cheaper (by a lot as well over the other) but I thought being pumped over 100 PSI all the time, won't the smaller ones be better? I was thinking about in a years time when they have stretched a bit, won't the bigger ones be the worse choice and go too baggy or something?
Sod it I will just get the dearer (narrower) ones lol. £14 vs £10 who cares.
Those are 105g... the Schwalbe ones I am erm... throwing on a bonfire... are 65g each. Silly! No wonder the rim tape is eating the rubber away. :shock:

Don't think of it as a size 'limit' - more of a guideline. I've run 23c road tubes with 35c cross tyres before. Nothing bad happened.0

Well I got the 20-25c in case I ever go back to 23c tyres.
Fitting a 25-32c inner tube into a 23c tyre doesn't sound right.0 -
I bought a new bike in November last year. It cam with 25mm tyres. The tubes inside were 18-23mm.I have only two things to say to that; Bo***cks0
