Can 700x38c inner tubes work in a 700x40c tyre? (Errors were made!)
Had a mare today, 3 punctures, a taxi ride to the nearest open bike shop (sadly only Halfords) and a train home later...
I asked for replacement tubes and was told this was what they had fitted and what would do the job ( I did query it at the time , but was tired and stressed).
My tyres are schwalbe marathon Mondial 700x40c which is obviously wider than the tubes purchased.
Will the spares work or, do I need to get new new spares from a proper bike shop when I can?
