Changing a tire can be challenging in the best of circumstances but to do it without a jack raises the stakes considerably. If you know how to change a tire, you can manage to fix a flat without a jack. It’s not easy but thinking it through ahead of time and having a plan of action can help considerably.
Science on Your Side
If you have the proper tools, enough physical strength, and an extra pair of hands, you can use a simple machine like a lever in place of a jack when you need to fix a flat. Find a metal pole or similarly shaped, sturdy object and a large rock, block or other heavy object to use as a fulcrum. Hold one end of the pole and place the other across the fulcrum and under the frame of the car. When you exert force down on the pole, the other side under the car should raise up with the pole, lifting the vehicle slightly. At this point, a second person should slide a block, rock or other object under the raised frame. Gently release the pole to lower the car onto the block. Loosen the lug nuts and then change the tire. Tighten the lug nuts slightly and perform the lift in reverse to return the car fully to the ground and then tighten the lug nuts completely.
A Hole in One
This method for changing a tire without a jack can be completed by a single person, although as with any tire change, caution is always needed in case the car rolls. Drive the car onto a block placed on the same side of the car as the flat. Make sure the emergency brake is on, and if you have wheel chocks, place them behind the other two wheels as a safety measure. Using a shovel — or even your hands in a true emergency — dig out the soil around and underneath the flat tire. Keep digging until you have enough room to change the tire. Again, loosen the lug nuts, change the tire, replace the lug nuts and tighten gently. Fill in the hole until you can drive out of it. Release the emergency brake and remove any wheel chocks. Then drive off the block and once all four tires are back on the ground, finish tightening the lug nuts.
