700x23 and 700x18

[Tetedelacourse]

With new tyres, 700 x 23, I got given a set of complimentary tubes, which are 700 x 18. Would there be a problem with using these tubes with these tyres?

No. Infact you are less likely to nip these inners putting the tyre back over the lip of the rim.

Most inners list a fairly wide range: 18-23, 23 -32, 28 -37, etc
