Bouncing on Words

We were on a borrowed Montero in San Francisco when we got a flat tire. On the way home, we decided to stop by a store a few exits from where we stayed. It was there that we discovered we had another flat. Good thing we had a spare. And two men in the car.
So the guys set out to change the tires – no easy task if you need to read the manual to get it done. After an hour and a string of hitches, the spare tire was in and the men proudly released the jack, But as soon as the newly installed tire hit the ground, we heard a hissing sound. All of us quickly grabbed the tools, threw them at the back of the Montero and jumped in.
