This reminds me of a similar thread in a parallel universe entitled "Spare tires and where you hide them":
1) It's somewhere in the car, I guess (I've never seen it).
2) They just get in the way, so I leave mine in the garage. My kids want me to make it into a tetherball stand.
3) Why would you want to carry a spare tire with you everywhere? I've never had a flat. You'll never need a spare tire unless you do something seriously wrong, like driving on nails.
4) I drag mine behind my car to keep the tailgaters off.
5) I hate spare tires, plus I wouldn't know how to deal with it. I just carry a cell phone. If something goes wrong my boyfriend will take care of it.
6) I have two! Plus, I'm towing a spare car. You just never know.
7) Under my belt, of course. But it kind of hangs over sometimes.
