Reinventing the flat tire is a far more common achievement than reinventing the wheel.
And this is in spite of the fact that most flat tires are a good deal more complex and clever than a wheel. A wheel solves a problem. A flat tire salves an ego. The better a wheel works, the less it is noticed. A flat tire requires us to stop, gives us a chance to admire someone's skill with a jack and tire iron and may beget all sorts of speculation as to why it is flat. Whatever drives one to invent a wheel passes away with the invention. The flat tire must be reinvented over and over again, even by the same person, since it does not solve the problem that sets the inventor in motion.
[I will gradually fill this yawning white space with examples as they occur to my strange mind but you doubtless have a few of your own.]
