Sometimes I wonder why I even keep the spares in my cars.
For instance, the space-saver spare in the T/A has never been used and still has its original can of propellant- which is great for car shows and associated originality points. The chances that it'll still work are pretty good, however we're talking about OEM equipment that is 24 years old! Is it really worth attempting to use in an emergency? Its better than nothing, right?
On the other hand, the spare will stay in the Miata. Its never been used, and despite being 21 years old, looks to be in excellent shape. Its so light that its worth holding onto and what little space I'll gain in the trunk isn't really worth removing it.
The car that should have a spare the most, the Corolla, had a crappy spare that I took out after it wouldn't hold air after an initial test.
I suppose what this argument comes down to is- is it worth keeping the old-a** spare in your old-a** car with all of the options available today? Now we've got cell phones, AAA, insurance related road side assistance, fix-a-flat etc which makes us less dependent on ourselves. I'm ashamed to think that most kids around driving age from here on out will never know how to change a flat tire. "Oh, I've got AAA for that, hahaha." Thats cool, go ahead and wait 45 minutes for those guys to show up- I'm going to be on my way in 10 minutes.
