So you have four flat tires. I guess it's possible all four could be punctured, but I doubt it. My guess is that you only need to find somebody who can show you how and what you need to inflate the tires, If you don't know anybody who bicycles regularly, I'd suggest taking both bikes to a local bike shop sometime in the middle of the week.
