Took the plunge and splashed out on some new rubber, fitted a set of 2.2 BC Rubber Queens today and really impressed with them - but I got wondering about the tubes as a lot of pictures of bikes running them seem to be a lot fatter!
Could just be other man's grass syndrome, but I was wondering what difference inner tube size made to the overall tyre performance? Don't have a clue about rubber.... I just point it on cheapo tyres and hold on normally I've got spesh tubes in there now which are sized up 2.0-2.2, on Mavic XM719. What's going to alter if I run them with a fatter tube?
