While about to head out in the car, I notice the back tire is totally flat, so much so that the rim is sitting on the floor! There is no way I could drive to the petrol station to put air in, the tire is way too low to drive on.I only have a foot pump and wearing open toe wood heels, I have no choice but to try and pump it up by foot, even if I'm not wearing the best shoes and have never done this before!
