    My bike runs a 25 tire but I was sold two 18-23 replacement tubes. Will those work fine for my bike when I get a flat? Or am I going to be in trouble using a tube that size?

    Thanks.

    They will work. There is a lot of variation among tires of the same nominal size. I think tubes come in 2 sizes narrow (for normal road bikes) and wide (for off road bikes).

    You have narrow tubes and a normal road bike tire.

    Plus with the narrow tubes you will save a few grams of rotating weight.

    More importantly then the weight, since the weight is very minor, is that it makes installing tires bit easier.

    Installing the tire easier is definitely more a realistic importance for me than the weight saving of several grams.........considering the "spare tire" I already have around my waist weighs way more than the inner tube. hahaha
