You need a spare tire, car jack, and lug nut wrench. Remove hub cap, loosen lug nuts, DO NOT remove or loosen completely. Jack up the car then finish removing the 5 lug nuts. Remove the bad tire and replace with your spare. Put the lug nuts back on the tire but do not tighten them completely yet. lower the jack until the car is on the ground. When tightening down the lug nuts make sure you do every other lug nut until they are all tightened down. You do it this way to ensure they are tightening the wheel equally. Road side assistance like AAA can help as well if you don't have the items you need to DIY.
