My tire blew out this morning. I looked in my trunk for my spare... apparently my tire shop didn't put the spare back in there (aka stole it) when they did my tires a few years ago. So now I need to get a spare to get it to the tire place to get the tire replaced. My other car's spare tire is too big.

What's the easiest way to go about doing this? Should I go to the tire shop and ask them if they have a spare I can put on it? Go buy one myself? Kind of a weird situation just looking for advice, thanks.
