Find a safe location to change your tire as you want to be out of the path of traffic if at all possible. If you have to stop on the side of the road, then turn on your hazard lights so that other drivers can see you.
Use the jack in the back of your car to support the vehicle. You'll also use it to lift the car a few inches off the ground. After loosening the lug nuts, you can remove the flat and put the spare on the car. Before driving in Corte Madera, CA, make sure to tighten the lug nuts and remove the jack from under the car.
