The only tools needed to change a tire are a jack, lug wrench, and spare tire. A lug wrench is a large socket wrench with one socket that fits over the lug nuts on your tire.
To change a car tire, begin by parking on a hard, level surface and turning your car off. Retrieve your jack, wrench and spare tire and find the flat tire. Using your wrench, loosen the lug nuts slightly. Next, find a suitable surface on the undercarriage of the vehicle to place your jack, and jack the vehicle up until the flat tire is off of the ground. Finish removing the lug nuts, then slip off the tire. Mount the spare tire, replace the lug nuts and lower the car from the jack.
