    the tube will stretch and u'll be fine, but it will be easier to get flats, cause the tube walls are stretched thinner, also idk why but it tends to deflate faster just sitting around, i had an undersized tube on my bike when my shop was out of the right size, and when i checked my tires it was always alot lower than the other tire

    I think if we pose the question "what's the least appropriate tube size you've ever used?" we'll might get some interesting answers.

    I had a 20x1.5" BMX tube in a 26x2.1" MTB tire for almost a year in the late 90s.

    my bike came with 1.7 tubes and it had 1.95 tires on it ... no extra leakage in fact these were the best tubes Ive had... kenda brand I think.... finally got 3 punctures on both of them.. that's my threshold the 4th flat and it is repaced. They worked better than the maxxis featherweight tubes that were 1.9-2.1. I gave up on being light and now just use the standard cheap tubes.
