How to Change a Flat Tire

A flat tire is stressful, but changing one is a manageable job when you know the sequence. The most important part is safety: choosing a good spot, securing the car, and working in the right order. Practice once in your driveway and you will feel far more confident if it ever happens on the road.

Get Safe First

As soon as you notice a flat, slow down gradually and look for a level, firm spot well away from traffic. A parking lot or wide shoulder is ideal. Avoid hills and soft ground. Turn on your hazard lights, set the parking brake, and put an automatic transmission in park or a manual in first or reverse. If the location feels unsafe, it is better to drive slowly to a safer place, or call roadside assistance.

Gather Your Tools

• The spare tire, checked for pressure
• The jack and the lug wrench, usually stored with the spare
• The owner's manual, which shows the correct jack points
• Wheel wedges or a sturdy rock to block a wheel
• A flashlight and gloves for low light or dirty work

Step-by-Step: Swapping the Tire

1. Block the wheels. Place a wedge behind or in front of a tire diagonal to the flat one, so the car cannot roll.
2. Remove any hubcap or wheel cover if there is one, then loosen each lug nut about a half turn with the wrench while the tire is still on the ground. Turn counterclockwise. The weight of the car keeps the wheel from spinning.
3. Place the jack at the correct point. Check the manual for the reinforced spot near the flat tire. Using the wrong point can damage the car or let it slip.
4. Raise the car until the flat tire is just off the ground, with enough clearance for the fully inflated spare. Never put any part of your body under a car held up only by a jack.
5. Remove the lug nuts completely and keep them together in a hubcap or your pocket. Pull the flat tire straight toward you.
6. Mount the spare by lining up the holes with the bolts. Push it fully onto the hub.
7. Hand-tighten the lug nuts, then snug them in a star pattern, which spreads the pressure evenly.
8. Lower the car until the tire touches the ground, remove the jack, and then tighten the nuts firmly in the star pattern again.
9. Stow everything, including the flat tire, jack, and tools.

What to Do After the Swap

Many spare tires are temporary and meant for limited speed and distance. Check the spare's sidewall and your manual for the limits, and drive accordingly. Have the lug nuts rechecked for tightness after a short drive, and visit a tire shop soon to repair or replace the flat. Also confirm the spare's air pressure, since spares often lose air while sitting unused.

Mistakes That Make the Job Harder

• Jacking the car up before loosening the lug nuts, which makes them far harder to break free.
• Using the wrong lift point and bending part of the frame or body.
• Skipping the wheel block, which lets the car shift.
• Tightening nuts in a circle instead of a star, which can seat the wheel unevenly.

The takeaway: park safely, loosen the nuts before lifting, use the correct jack point, and tighten in a star pattern. If conditions are unsafe or the tire is damaged beyond a spare swap, call for roadside help and wait somewhere secure.
