As I sit here our car is in the drive with yet another flat. Last friday I had the tires rotated & Saturday night it was totally flat. We own an old air compressor, which luckily pumped the tire enough to get to the gas station to pump again! Took the car in Monday, they said there was a nail .Tues morning the tire is flat again! We couldn't pump it until later in the day so as of 4:00 today it was said they replaced the tire. I just walked outside and our tires is flat!! So tomorrow I'm not sure how this is going down?? Serious !!!
