How do I change a flat tire?

Efficient

Changing a flat tire is a manageable task if you stay calm and prioritize your safety. Here is how to do it:

1. Find a Safe Spot

Pull over to a flat, level area as far away from traffic as possible. Turn on your hazard lights and engage the parking brake firmly. If you have wheel wedges (or a heavy rock/brick), place them behind the tires opposite the flat to prevent rolling.

2. Gather Your Tools

Locate your spare tire, jack, and lug wrench. These are usually stored in the trunk or under the floor mat of the vehicle. Consult your owner's manual if you are unsure where they are kept.

3. Loosen the Lug Nuts

Before you jack up the car, use the lug wrench to loosen the lug nuts on the flat tire. Turn them counter-clockwise about half a turn, but do not remove them yet. The resistance from the ground helps keep the tire from spinning while you break the tension.

4. Lift the Vehicle

Place the jack under the vehicle’s frame at the designated jacking point (refer to your owner's manual for the specific location). Slowly operate the jack to lift the car until the flat tire is about six inches off the ground.

5. Remove the Flat Tire

Remove the lug nuts completely by hand and pull the flat tire toward you until it is free from the wheel studs. Lay it flat on the ground so it doesn't roll away.

6. Mount the Spare

Align the holes of the spare tire with the wheel studs and push the tire onto the hub. Replace the lug nuts and tighten them by hand until they are snug.

7. Lower and Tighten

Lower the vehicle until the spare tire touches the ground but isn't bearing the full weight of the car yet. Use the lug wrench to tighten the lug nuts in a "star" pattern (tightening opposite nuts rather than adjacent ones) to ensure the wheel is seated evenly. Finally, lower the car completely and remove the jack. Give the lug nuts one final, firm tighten with the wrench.

Important Tips:

  • Speed: Spare tires (especially "donuts") are often temporary. Check the sidewall for speed and distance restrictions.
  • Service: Once you have the spare on, drive slowly and head to a professional mechanic or tire shop as soon as possible to repair or replace your original tire.
  • Safety: If you ever feel unsafe on the side of a busy road, call for roadside assistance rather than attempting the change yourself.
