23to32c tubes in 35c tyre.

[Banjo]

I recently bought some scwalbe durano raceguard 35c tyres for my heavyweight steel tourer / do everything bike.

They replaced a worn out pair of 25c durano plus.
I didnt think to get new tubes so used the old ones which were sized for 23 to 32c . They seem to be ok after a few short rides .Would it be advisable for me to replace them for larger tubes asap or dont worry.

You're talking 3mm difference. It's no problem Banjo

Cheers Ian I vaguely remember it was you that got me into the bomb proof qualities of Duranos in the first place ! I remember doing an audax in hedge cutting season and changing 2 tubes and a couple of stick on patches to get round. Duranos not quite so supple as lighter faster tyres but for me they transformed my rides from the frustration of multiple fairy visits.

And the old ones will have stretched a little.
