Well, probably not, but hopefully you've put air in it in the last few months. Most people love to hate them, actually. You can post up with whatever measure of love or hate you have for these things if you really want. But the real tech questions here are: how long do these things last in the trunk, and what do you do after that? Seems like I'm in charge of fleet maintenance for my adult children and they all have cars older than 10 years old so it would stand to reason that the temporary spares in them have "aged out," if you believe, even a little, that unused tires age out. So, should I replace them? With what, a real tire? Or another temporary spare? Where do you get one?
