tubes for 23mm and 25mm tyres

[kingfisher]

I've been using 23 mms tyres for some time but thought I may try 25mm ( both Michelin).
I currently use Michelin latex tubes that are marked 22 - 23 x 700.
I also have several new tubes in my current stock.

OK to use these in the 25mms version cover ?

Thanks.

Yeah bung them in. Most tubes have size range and one brands 25 is anothers 23 and you won't notice the difference.

Beware puncturing your fancy latex inner tubes if the fit of your new tyres is really tight. For this reason I stick to quick thick conventional inner tubes.

the new tyres are not particularly a tight fit - and i've had very little problem with latex tubes over the last 20 + years but... I suspect if that is a problem that people are having is may be because the 'suitable for tubeless' covers are made with a much tighter fit?

For the last 20 years I've used mostly 25c tyres and have always bought 23c tubes, sometimes labelled 18-23, or 20-23 never had a problem.

Thanks people.
Yep I've now done a couple of hundred miles on 25s with the 'original' size tubes - with no ill effects!
