You can replace a tire yourself with basic tools, or have a shop do it for you

Replacing a tire means removing the old one from the wheel and putting a new one on. You have two paths: do it yourself at home with a jack, lug wrench, and new tire, or drive to a tire shop and let them handle it. The DIY route takes 20 to 30 minutes once you have the right tools and a replacement tire. A shop typically charges $15 to $50 per tire for labor, plus the cost of the tire itself, and you can wait while they work or drop the car off.

The main decision is whether you have the tools, the physical ability to use them, and a safe place to work. If your car is on a busy road or you have mobility concerns, a shop is the better choice. If you are in a safe location with a flat driveway and you want to save money, the DIY method is straightforward once you know the steps.

Key Takeaways

  • You will need a spare tire (or new tire), a jack, a lug wrench, and a wheel wedge or heavy object to prevent the car from rolling.
  • The process involves loosening lug nuts while the tire is still on the ground, raising the car, removing the old tire, and installing the new one.
  • Tighten lug nuts by hand first, lower the car, then tighten them fully in a star or cross pattern to may support even pressure.
  • If you do not have a spare or the tools, or if the car is in an unsafe location, calling a tire shop or roadside information is the faster option.

Gather your tools and check your spare tire before you start

Before you begin, make sure you have everything you need. You will need a jack (usually comes with your car in the trunk), a lug wrench (the cross-shaped tool that fits your lug nuts), a spare tire or new tire, and ideally a wheel wedge or a heavy block to place behind the wheels so the car does not roll. If you do not have a spare, you will need to buy or obtain a replacement tire first.

Check that your spare tire has air in it. Press on it with your hand — it should feel firm, not soft or flat. If it is flat, you will need to inflate it at a gas station or tire shop before you can use it. Some cars have a full-size spare in the trunk; others have a small temporary spare. Either works, but a temporary spare is meant only for short distances at lower speeds, so plan to replace it with a full tire soon after.

Park on a flat, level surface away from traffic if possible. If you are on a highway, move to the shoulder as far from traffic as you can. Turn on your hazard lights. This is the safest setup for the work ahead.

Loosen the lug nuts while the tire is still on the ground

Do not raise the car yet. While the tire is still touching the ground and the car is stable, use the lug wrench to loosen the lug nuts that hold the wheel on. You will turn the wrench counterclockwise. The lug nuts will be stiff — this is normal. You may need to put your full weight on the wrench or step on it to break them free.

Loosen all the lug nuts, but do not remove them completely. Just turn each one a half turn or so until they are loose enough to turn by hand. This step is important because once the car is raised, the wheel will spin if you try to loosen the nuts, and you will not be able to get them off.

Raise the car with the jack and remove the old tire

Locate the jacking point on your car. This is usually a reinforced spot on the frame just behind the front wheel or just in front of the rear wheel. Your owner's manual shows exactly where it is. Place the jack under this point and raise the car until the tire is about six inches off the ground. Raise it slowly and watch to make sure the car is stable.

Once the car is raised, finish removing the lug nuts by hand and set them aside in a safe place where you will not lose them. Pull the wheel straight toward you to remove it from the hub. It may take some force. Set the old tire on its side nearby.

Install the new tire and hand-tighten the lug nuts

Lift the new or spare tire and line up the holes in the wheel with the bolts on the hub. Push it straight onto the hub until it sits flush against the wheel. This takes some strength, but it should slide on without excessive force.

Thread the lug nuts back on by hand, turning them clockwise. Tighten them as much as you can by hand, but do not use the wrench yet. The goal is just to hold the wheel in place while the car is still raised. Hand-tightening prevents you from over-tightening and damaging the bolts.

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

Slowly lower the car by turning the jack handle or lever until the tire touches the ground and the car's full weight is on it. Lower it completely and remove the jack. Now use the lug wrench to tighten the lug nuts fully.

Tighten them in a star or cross pattern, not in a circle. If the lug nuts are at 12, 3, 6, and 9 o'clock, tighten 12, then 6, then 3, then 9. If there are five lug nuts, tighten them in a star pattern as well. This ensures the wheel is pulled evenly onto the hub. Tighten each nut firmly, but do not over-tighten — you should feel resistance, not have to strain with all your strength.

Once all lug nuts are tight, your tire replacement is complete. Drive slowly for the first few miles to make sure everything feels normal. If you used a temporary spare, remember that it is not meant for long-term use, so visit a tire shop within a few days to install a full-size tire.

When to take your car to a tire shop instead

If your car is parked on a slope, a busy road, or anywhere you do not feel safe working, do not attempt this yourself. Call a tire shop or roadside information service and let them handle it. The cost is worth your safety.

If you do not have a spare tire, a jack, or a lug wrench, you will need to obtain these items first. Some cars no longer come with a spare, so check your trunk. If yours does not have one, you can buy a temporary spare online or at an auto parts store, but it is easier to just call a shop and have them bring a tire to you or tow your car in.

If the lug nuts are stuck or rusted and will not budge, or if the wheel itself is stuck to the hub, a shop has better tools to handle this without damaging your car. Forcing it can strip the bolts or damage the wheel, which costs more to fix later.

Frequently Asked Questions

How tight should the lug nuts be?

Tight enough that you feel firm resistance when you turn the wrench, but not so tight that you have to strain or jump on the wrench. Over-tightening can strip the bolts or warp the wheel. If you have a torque wrench, your owner's manual lists the correct torque specification, usually between 80 and 120 foot-pounds depending on your car.

Can I replace a tire in the rain or on wet pavement?

Yes, but it is harder and less safe. Wet pavement makes it easier for the car to slip off the jack. If possible, wait for dry conditions or move to a covered area. If you must do it in the rain, work slowly and double-check that the jack is stable before you get under or near the car.

What if the spare tire is also flat?

You cannot use a flat spare. Call roadside information or a tow truck to take your car to a tire shop. They can inflate the spare on the way or bring a replacement tire with them. Do not attempt to drive on a flat tire, as it damages the wheel and the tire beyond repair.

Do I need to replace all four tires at once?

No. You can replace one tire at a time. However, if the remaining tires are very worn or mismatched in tread depth, your car may not handle well. A tire shop can tell you whether the other tires are safe to keep driving on.

Should I get the wheels balanced after replacing a tire?

Yes, if you are installing a new tire. Balancing costs $15 to $30 per wheel and ensures the tire wears evenly and the car does not vibrate at highway speeds. If you are using a spare, balancing is less critical since the spare is temporary, but it is still a good idea if you plan to drive long distances.
