Getting a flat tire while driving can be stressful, especially if you’ve never had to change one before. But don’t worry—you don’t need to be a mechanic to fix it.
With a spare tire and the right tools, you can do it yourself in less than 30 minutes. This guide will help you put on a spare tire step by step in a simple way anyone can follow.
What You’ll Need
Before you start, gather these basic tools from your car. Most of them are already in the trunk or under the back panel.
- Spare tire – Make sure it’s fully inflated.
- Car jack – Used to lift the car.
- Lug wrench (tire iron) – For loosening and tightening the lug nuts.
- Owner’s manual – Shows where to place the jack and other safety tips.
- Flashlight – Handy if it’s dark.
- Gloves – Optional, but keeps your hands clean.
- Wheel wedges or bricks – To stop the car from rolling.
Having all these ready before starting makes the process safer and smoother.
Step 1: Find a Safe Place to Pull Over
As soon as you feel or hear a flat tire, slow down and turn on your hazard lights. Don’t slam the brakes. Look for a wide, level spot away from traffic. A parking lot or rest area is perfect. If you’re on a road, try to find a shoulder or a straight stretch—not a hill or curve.
Why this matters:
A flat surface keeps your car steady while you change the tire. Avoid soft ground that could cause the jack to tip.
Step 2: Turn Off the Engine and Apply the Parking Brake
Once you’ve parked in a safe place:
- Turn off your engine.
- Put the gear in “Park” (or first gear if it’s a manual).
- Pull the parking brake all the way up.
- Safety First. Turn on your hazard lights to alert oncoming traffic that you are parked. Place road flares or reflective triangles 100-150 feet behind your vehicle to create a buffer zone.
To add extra safety, put wheel wedges or bricks behind the opposite tires—this stops the car from rolling while it’s on the jack.
Step 3: Get Your Spare Tire and Tools
Open your trunk and look under the floor panel. You should see the spare tire, jack, and lug wrench stored together. Some SUVs have the spare tire mounted underneath the rear of the vehicle.
Pro tip:
Check the tire pressure on your spare once in a while. You don’t want to find it flat when you need it most!
Step 4: Loosen the Lug Nuts (But Don’t Remove Them Yet)
Lug nuts are the round bolts in the middle of the wheel that keep the tire attached.
- Use your lug wrench to turn them counterclockwise (to the left).
- It might be hard at first—use your foot to carefully push down on the wrench if needed.
- Just loosen them, don’t take them off all the way yet.
Why not remove them now?
The tire is more stable when it’s still on the ground, which makes loosening easier.
Step 5: Use the Jack to Lift the Car
Every car has specific jack points. These are strong spots under the frame near each wheel. Check your owner’s manual to find them.
- Place the jack underneath the correct spot near the flat tire.
- Slowly turn the handle or crank to raise the car.
- Lift it until the flat tire is about 6 inches off the ground.
Safety tip:
Never place your body under the car when it’s lifted with a jack.
Step 6: Remove the Lug Nuts and Flat Tire
Now that the car is off the ground, go back and fully unscrew the loosened lug nuts. Keep them in one place so they don’t roll away.
- Pull the flat tire straight toward you.
- Set it down flat next to your car—it can act as a backup in case the jack fails.
Helpful hint:
If the tire won’t come off, hit the rubber gently with your palm or foot to loosen rusted parts.
Step 7: Put the Spare Tire On
Now grab your spare tire and line up the holes with the bolts (or studs) on the wheel hub.
- Push the tire in until it’s flush with the metal backing.
- Hand-tighten the lug nuts onto the bolts in a crisscross or star pattern.
Why the star pattern?
It makes sure the tire tightens evenly and sits flat against the car.
Step 8: Lower the Car and Tighten the Lug Nuts
Once the spare tire is in place and the nuts are on by hand:
- Slowly lower the car back to the ground with the jack.
- Once it’s fully down, remove the jack.
Now use the lug wrench to fully tighten the nuts. Again, use the star pattern and go around twice if needed to ensure they’re tight.
Don’t over-tighten. You’ll just need them firm and snug, not superhuman tight.
Step 9: Clean Up and Double-Check
Now that the spare is on and tight:
- Put the flat tire in your trunk.
- Pack away your jack and tools.
- Look at the spare to make sure it’s straight and firm.
- If you used wheel wedges or bricks, remove them.
Give everything a final check before hitting the road.
Step 10: Drive to a Tire Shop ASAP
Most spare tires aren’t made for long trips. Especially if it’s a “donut” (small temporary tire), it has limits.
- Drive no faster than 50 mph.
- Try to replace your flat tire within 50–70 miles.
A tire shop can repair your original tire or replace it completely.
Final Thoughts
Changing a flat tire might seem scary, but with the right steps and tools, it’s something anyone can do.
Knowing how to put on a spare tire can save you time, money, and stress in an emergency. Just remember to stay calm, follow each step carefully, and drive slowly on the spare until you get to a repair shop.
Always have your automotive technician check your spare tire every few months to ensure it’s in good condition so it’s ready when you need it. With a little practice, you’ll feel confident and prepared to handle this common roadside problem like a pro.
