23mm tube in a 25mm tire?

[faken]

Hi everyone.

I recently purchased a new set of 25mm tires, (Vittoria Open Corsa EVO CX), am I able to use my 23mm Michelin latex tubes with them, or is that a no go?

A.

Yes.

I have done this with no ill effects apart from faster overnight deflation.

Awesome. Not gonna bother with buying new tubes then.

I'm running 65g 18-23mm R'Air tubes in 30mm Strada Biancas that come to 31mm on my rims...

Tubes can stretch a fair amount without any ill effects. A skinny road racing tube will fit up to 28mm with no problems. If you try to put a 23-25mm tube into a 35mm fat tire, then you can have problems.

I´ve never had a problem for using skinny tubes

I've used 18-23mm in 35m tires with no problems at all. Shockingly.

They must get pretty thin, and certainly look funny when you remove them.
