ive basically had a tear in my tyre and i now need to replace it, the current tyre size is 700x25. i had my eye on a very nice new tyre https://www.highonbikes.com/media/ca...gano_blu_1.jpg it goes with my saddle but the size of that is 700x23...now i know that its 2 mm shorter than the current tyre, does this make any difference? at all? also what about if i was to buy a smaller inner tube to fit that tyre?
