You can change a car tire yourself with basic tools and about 15 to 20 minutes

Changing a tire is a mechanical task you can do at the roadside without special training or equipment beyond what most cars carry. You will need a jack (usually in your trunk), a lug wrench (the cross-shaped tool that fits your wheel bolts), and a spare tire. The process involves loosening bolts while the car is still on the ground, raising the car with the jack, removing the old tire, installing the spare, and tightening the bolts in a specific order. Most people complete this in under 20 minutes once they have done it once.

The hardest part is usually the first step — breaking the lug nuts loose — because they are installed very tight at the factory. Everything after that is straightforward mechanical work. If you cannot loosen the lug nuts by hand, you may need to use your body weight or a breaker bar, but do not force it so hard that you strip the bolt.

Key Takeaways

  • Loosen the lug nuts with the car still on the ground, then raise the car with the jack before removing the wheel.
  • The jack should be placed on the reinforced frame point under your car, not on the plastic trim or rocker panel.
  • Tighten the lug nuts in a star or cross pattern, not in a circle, so the wheel sits evenly.
  • After driving a few miles on a spare tire, have the lug nuts re-tightened at a shop because they often loosen slightly after installation.

Locate the jack point and gather your tools

Open your trunk and remove the spare tire, jack, and lug wrench. Most cars store these items in a compartment under the trunk floor or along the side wall. Check your owner's manual if you cannot find them — some newer vehicles store the jack in a different location or use a different design.

Find the jack point on your car. This is a reinforced area of the frame designed to support the weight of the vehicle. It is usually a small notch or raised area along the rocker panel (the side of the car below the doors). Your owner's manual shows the exact location for your model. Never place the jack on plastic trim, the fuel tank, or any area that is not reinforced — the car can slip and cause serious injury.

Park on level ground away from traffic if possible. Turn on your hazard lights. If you are on a highway, move as far from the roadway as you safely can.

Loosen the lug nuts before raising the car

This step is critical: loosen the lug nuts while all four wheels are on the ground and the car's weight is holding the wheel in place. If you raise the car first, the wheel will spin freely and you will not be able to loosen the bolts.

Place the lug wrench on one lug nut and turn it counterclockwise. Push down on the wrench handle with your body weight rather than just your arm strength. The bolts are installed very tight, and you may need to step on the wrench or use a breaker bar to break them loose. Loosen all five lug nuts (or however many your car has) by one or two turns each — do not remove them completely yet.

Raise the car with the jack

Position the jack under the reinforced jack point closest to the flat tire. Most jacks have a notch or hook that must align with the frame. Raise the car slowly and steadily until the tire is about six inches off the ground — high enough that you can remove the old tire and install the spare without the car settling on the rim.

Do not go higher than necessary. The higher the car, the less stable it is. If you are on soft ground, place a board or flat rock under the jack to prevent it from sinking.

Once the car is raised, finish removing the lug nuts by hand and set them in a safe place where you will not lose them — many people place them in the hubcap or a cup. Remove the old tire by pulling it straight toward you. It may be stuck slightly; rock it gently side to side if needed.

Install the spare tire and hand-tighten the lug nuts

Align the holes on the spare tire with the bolts on the wheel hub. Push the spare straight onto the bolts until it sits flush against the hub. This may require some force, but it should not be difficult — if it does not fit, check that you have the right orientation.

Thread the lug nuts back on by hand and tighten them as much as you can without tools. This holds the wheel in place while you lower the car. Do not fully tighten them yet — you need to do that with the car back on the ground.

Lower the car and tighten the lug nuts in a star pattern

Lower the car slowly by turning the jack handle or lever (depending on your jack type) counterclockwise. Lower it until the tire touches the ground and the car's full weight is on the wheel. Then lower it the rest of the way and remove the jack.

Now tighten the lug nuts fully using the lug wrench. This is the most important step for safety: tighten them in a star or cross pattern, not in a circle. If your car has five lug nuts, tighten them in this order: top, bottom-left, top-right, bottom-right, then bottom-left again. If it has four, tighten opposite corners alternately. This ensures the wheel sits evenly and the bolts are equally tight.

Tighten each bolt firmly but do not over-tighten — you should feel strong resistance, but you should not need to strain. If you over-tighten, you risk stripping the bolt or making it impossible to remove next time.

Stow the old tire and have the lug nuts checked soon

Place the old tire in your trunk. Most spare tires are temporary and are not designed for long-term driving — check your owner's manual for the speed and distance limits. Temporary spares are usually rated for 50 miles per hour and 70 miles of driving.

Drive to a tire shop or service station within the next few days and have the lug nuts re-tightened. After you drive on a newly installed wheel, the bolts often loosen slightly as the tire settles. A shop can check them and tighten them if needed, usually for free or a small fee. This takes five minutes and prevents the wheel from coming loose later.

Frequently Asked Questions

What if I cannot loosen the lug nuts by hand?

Use a breaker bar — a longer metal rod that slides over the lug wrench handle to give you more leverage. You can also try standing on the wrench handle or rocking it back and forth gently. If the bolts are truly stuck, do not force them so hard that you risk injury; call a tow truck instead.

Can I use a scissor jack or a bottle jack instead of the factory jack?

Yes, but only if it is rated for your car's weight and you place it on solid ground. A scissor jack is slower but more stable than many factory jacks. A bottle jack is compact but can tip if not used carefully. Always use a jack stand as a backup — never work under a car supported only by a jack.

What if the spare tire is also flat?

Check it before you need it. Most people discover a flat spare only when they have a flat tire. If your spare is flat, call a tow truck or roadside information. Do not drive on a flat spare — you risk damaging the rim and making the problem much more expensive.

How tight should the lug nuts be?

Tight enough that you cannot turn them by hand with the wrench, but not so tight that you need to strain or jump on the wrench. Most cars specify a torque value in the owner's manual (usually between 80 and 120 foot-pounds). A tire shop can tighten them to the exact specification with a torque wrench.

Do I need to replace the spare tire after using it?

Not when ready, but have the old tire repaired or replaced soon. A temporary spare is not meant for permanent use. If the old tire can be repaired, a shop can do that for a low cost. If it cannot, you will need a new tire, but you can drive on the spare until then.
