How to Change a Flat Tire

Complete guide to safely changing a flat tire, from finding a safe location to securing the spare and checking tire pressure.

Things You'll Need

  • Spare tire
  • Jack
  • Lug wrench
  • Wheel wedges
  • Gloves

Steps

  1. 1

    Find a Safe Location

    Pull over to a flat, stable surface away from traffic. Avoid curves and slopes. Turn on your hazard lights immediately.

  2. 2

    Consult the Manual

    Check your owner's manual for the exact location of the jack, spare tire, and lug wrench. The jack point location varies by vehicle.

  3. 3

    Secure the Vehicle

    Place a wheel wedge or heavy object against the tire diagonally opposite the flat tire to prevent rolling. Engage the parking brake.

  4. 4

    Remove the Hubcap

    If your vehicle has a hubcap covering the lug nuts, use the flat end of the lug wrench to pry it off. Some vehicles have decorative center caps that pop off.

  5. 5

    Loosen the Lug Nuts

    Use the lug wrench to break the lug nuts loose by turning counterclockwise. Do this while the tire is still on the ground — you need the tire's weight to prevent spinning.

  6. 6

    Position the Jack

    Place the jack under the designated jack point on the vehicle's frame. Consult your manual for the exact location. Never place the jack under the body panels or trim.

  7. 7

    Lift the Vehicle

    Pump or crank the jack to lift the vehicle until the flat tire is about 6-12 inches off the ground. Make sure the vehicle is stable before proceeding.

  8. 8

    Remove the Lug Nuts

    Fully remove all lug nuts by hand and set them aside in a safe place where they won't roll away. Check that the lug nuts are not damaged.

  9. 9

    Remove the Flat Tire

    Pull the flat tire straight off the wheel studs. If it is stuck, wiggle it gently or tap the back with your fist. Never kick the tire.

  10. 10

    Mount the Spare

    Align the spare tire's rim with the wheel studs and push it onto the studs until it is centered and flush against the brake rotor or drum.

  11. 11

    Hand-Tighten Lug Nuts

    Thread the lug nuts onto the studs by hand in a star or crisscross pattern. This ensures even tightening. Do not use the wrench yet.

  12. 12

    Lower the Vehicle

    Pump or crank the jack to slowly lower the vehicle back to the ground. Lower it until the tire just touches the ground — keep the jack in place for now.

  13. 13

    Tighten Lug Nuts

    Using the lug wrench, tighten the lug nuts in a star or crisscross pattern. Tighten them firmly but not so hard that you damage the studs.

  14. 14

    Fully Lower and Remove Jack

    Completely lower the vehicle to the ground and remove the jack. The vehicle should be resting firmly on all four tires.

  15. 15

    Fully Tighten Lug Nuts

    Using the lug wrench, tighten all lug nuts as firmly as possible. If your vehicle has a torque wrench, consult the manual for the recommended torque specification.

  16. 16

    Remove Wheel Wedges

    Remove the wheel wedges or heavy objects you placed earlier. Stow them in the vehicle.

  17. 17

    Check Tire Pressure

    Use a tire pressure gauge to check the spare tire's pressure. Many spares are underinflated — inflate to the recommended PSI if needed.

  18. 18

    Stow the Flat Tire

    Place the flat tire in the designated storage location — usually under the floor mat in the trunk or mounted on the back of the vehicle. Secure it so it doesn't roll around.

  19. 19

    Stow the Jack and Tools

    Return the jack, lug wrench, and wheel wedges to their designated storage locations in the vehicle.

  20. 20

    Test Drive Carefully

    Drive slowly for the first few miles. Avoid highway speeds, sharp turns, and hard braking. The spare tire may have a speed and distance limit.

  21. 21

    Check Lug Nuts Again

    After driving 25 miles, stop and check that all lug nuts are still tight. Re-tighten if necessary — this is a critical safety step.

  22. 22

    Visit a Tire Shop

    Spare tires are temporary solutions. Visit a tire shop to repair or replace the flat tire and check the condition of all four tires.

  23. 23

    Check Spare Tire Age

    Spare tires degrade over time even if unused. Check the manufacturing date on the sidewall — replace if older than 6-7 years.

  24. 24

    Learn Regular Maintenance

    Check tire pressure monthly, rotate tires every 5,000-7,500 miles, and inspect tread depth regularly to prevent flats.

  25. 25

    Practice the Procedure

    Practice changing a tire at home on a dry day before you need to do it on the road. Familiarity with the process reduces stress during an actual emergency.

Tips

  • Always loosen lug nuts before lifting the vehicle
  • Tighten lug nuts in a star pattern for even pressure
  • Check lug nut tightness after the first 25 miles of driving
  • Spare tires are temporary — replace or repair the flat promptly

Warnings

  • Never place any part of your body under the vehicle while it is supported only by a jack
  • Do not use the jack on a slope or soft surface — find a flat, hard surface
  • Do not exceed the spare tire's speed or distance limits
