How to change a flat tire
... tire, car jack, crowbar, and lug nut wrench. The spare tire is almost always located underneath the floor mat in the trunk. Unless, of course, your car doesn't have a trunk. If you own an SUV, minivan or pickup, the spare tire is often mounted on the back of the tailgate or underneath the vehicle itself. Next, you need to set the jack up under a solid part of the side of the car, usually next to the flat tire toward the middle of the car.

Set the lugs aside in a secure location where they can't roll away. Now remove the flat tire and place it aside, and get the spare tire. Position the spare tire over the wheel studs. This is the most physically challenging part of the whole process. You'll have to hold up the tire and try to line up the holes in the wheel with the wheel studs located on the brake hub. One trick that might help is to balance the tire on your foot while you move it into position. After you have the spare tire hanging on the wheel studs, screw each of the wheel lugs back on. You'll want to start them by hand. Make sure you do not cross-thread them. The lugs should screw on easily. Once each of them is snug and you can't tight...
