A motorist experienced a flat tire on the driver side rear wheel of his car and went through the following procedure to replace the flat tire with the spare. The tire change occurred in the middle of the day in his own driveway about 20 ft in front of his garage. He first secured the other three wheels of the car with six bricks from his garage to prevent the vehicle from rolling (two trips back and forth to the garage). He then took out the jack, crank, and lug nut wrench from the trunk of the car, and read over the attached instructions for operating jack. He then removed the spare tire from the trunk and placed it near the rear left wheel. Next, he proceeded to position the jack under the car at the recommended support beam on the car frame. He then began to turn the crank to elevate the car. After the left rear portion of the car was lifted a few inches, but before the flat tire was lifted from the driveway surface, he used the lug nut wrench to loosen the five lug nuts securing the tire to the wheel hub. He then returned to the task of elevating the car, turning the jack crank until the flat tire was completely off the driveway surface. The next step was to remove the loosened lug nuts, placing them in a nearby position within reach. The flat tire was then removed and lifted into the trunk. The motorist then moved the spare tire into position and lifted it onto the five studs protruding from the wheel hub. He then reached for the five lug nuts, one at a time, placing them onto the studs and rotating them until finger tight. The lug nut wrench was then used to tighten the five nuts. With the tire secure, he proceeded to lower the car by cranking the jack down slowly until the spare tire supported the car. For good measure, he again tightened the five lug nuts now that the car was securely on the ground. He then collected the hardware, put it back into the trunk, and removed the bricks from the other three wheels and put them back into his garage.
