Flat tires are an unpleasant but inevitable part of driving, and being prepared to handle them can save you time, money, and unnecessary stress. Whether you’re on a long road trip or just heading to work, knowing how to change a flat tire by yourself is a crucial life skill. This comprehensive guide walks you through every step of the process, from identifying a flat to safely restoring your car to the road. We cover all the essentials, including tools you should have and safety tips to keep in mind.
Why Changing a Flat Tire Yourself Is Essential
Flat tires rarely happen at convenient times or in convenient places. Waiting for roadside assistance can leave you stranded for hours. In contrast, being able to change your own tire not only gives you independence but also ensures you can manage the situation without relying on others.
More importantly, understanding this procedure can also prevent further damage to your vehicle. Driving even a short distance on a flat tire can bend the rim, damage the suspension, or cause misalignment issues.
Tools and Equipment You Need to Change a Flat Tire
Before you start, ensure you have the following tools readily available in your vehicle:
- Spare tire (either full-size or temporary “donut”)
- Lug wrench or tire iron
- Car jack (typically included in your vehicle’s toolkit)
- Owner’s manual (for specific vehicle instructions)
- Flashlight or portable light (for nighttime assistance)
- Wheel wedges or bricks (for safety on inclines)
- Clean rag or towel
Not all these items will be in your car unless you’ve checked or purchased them, so routine vehicle maintenance includes verifying that your emergency kit is complete.
Step-by-Step Guide: How to Change a Flat Tire by Yourself
This section will break down the process into manageable steps to make changing a flat tire safer and easier to follow, especially if you’ve never done it before on your own.
Step 1: Find a Safe Location
If you notice that your tire is going flat while driving, resist the urge to slam on your brakes. Sudden movements can be dangerous. Instead, grip the steering wheel firmly and gradually slow down. Look for a flat, stable, and safe surface away from traffic—ideally on the shoulder or in a parking lot.
What to Avoid:
- Driving onto grassy or soft ground (the jack could sink or tilt)
- Parking on uneven or sloped terrain unless you use wheel wedges
- Bridges or tunnels (risk of exhaust fume accumulation)
Make sure your hazard lights are on, and apply the parking brake once you’ve stopped completely.
Step 2: Secure Your Vehicle
Before stepping out to change the tire, take safety precautions to prevent the car from moving.
- Engage the parking brake firmly.
- If your vehicle has a manual transmission, place it in gear (first or reverse).
- Place wheel wedges or heavy objects like bricks in front of or behind tires on the same axle for added stability.
This is essential for avoiding car movement while working near it and preventing accidents.
Step 3: Retrieve Your Tools and Spare Tire
Open your trunk or vehicle compartment where the spare tire, jack, and lug wrench are stored. Most compact spare tires (called “donut” tires) are located under the trunk floor or behind a panel.
Lift and place the tools and spare near the flat tire location. Be sure to inspect your spare to ensure it’s properly inflated before starting. A flat spare is not helpful!
Step 4: Loosen the Lug Nuts
Before lifting the vehicle, you must loosen the lug nuts that secure the flat tire to the wheel hub. Using your lug wrench or tire iron:
- Turn the wrench counterclockwise to break the lug nuts loose.
- If your lug nuts are too tight, you may need to provide additional force with your body weight—but be careful.
- Do NOT remove the lug nuts completely yet; just break them loose by a half-turn each.
This step helps prevent the tire from spinning when you lift it and makes removal easier once the car is elevated.
Step 5: Position and Raise the Jack
Consult your vehicle’s manual to find the correct jacking point—usually a reinforced section near the side sill closest to the flat tire. Never place the jack under bumpers or plastic components.
- Slide the jack into the designated jacking point.
- Begin cranking the jack handle until the tire is a few inches off the ground. In electric jacks, use the controls as per manufacturer instructions.
- Ensure the jack is stable and the platform is flush with the jacking point.
Do not place any body parts under the car at this stage! Safety comes first.
Step 6: Remove the Lug Nuts and Flat Tire
With the flat tire off the ground:
- Completely remove the lug nuts.
- Place them in a secure, visible location such as a cup or pouch to avoid losing them.
- Gently pull the flat tire straight toward you until it comes off the wheel studs.
- Set the flat tire aside temporarily.
If your vehicle has more difficulty removing the tire, you can tap the tire lightly with your foot to loosen it.
Step 7: Mount the Spare Tire
This is where you transition from the old to the new. Take your spare tire and:
- Align the holes in the wheel with the wheel studs.
- Pull it onto the hub firmly so it sits flush.
- Replace the lug nuts by hand, one at a time, to ensure even tension.
Make sure the spare is positioned correctly, facing the same direction as the other tire—no upside-down mounting allowed.
Step 8: Tighten the Lug Nuts by Hand
With the spare tire in place:
- Turn each lug nut clockwise until snug. This is only temporary tightening.
- Ensure the lug nuts are seated properly, but don’t crank them too hard just yet.
Tightening them while the vehicle is still jacked up prevents you from over-torquing the nuts before the tire meets the ground.
Step 9: Lower the Vehicle and Re-Tighten the Lug Nuts
Now, carefully lower the vehicle using your jack:
- Turn the jack handle slowly to lower the car until it rests lightly on the ground.
- Use your body weight to push down on the lug wrench for added leverage and fully tighten the nuts in a star pattern (alternating lugs to ensure even pressure).
- Final tightening ensures a secure fit and helps avert loose nuts later.
Do not remove the jack completely yet—just lower the tire pressure onto the ground.
Step 10: Fully Lower the Vehicle and Clean Up
Once the lug nuts are fully tightened:
- Lower the jack completely and remove it from beneath the car.
- Gather your tools and the flat tire, returning them to your trunk or undercarriage storage.
- Double-check to ensure you aren’t leaving something behind like a hubcap or wrench.
Your spare tire is now installed and ready for the drive to a tire shop or home.
Step 11: Drive Safely to a Service Center
Remember that most donut spare tires are not designed for speeds higher than 50 mph (80 km/h) or for long distances. Refer to your manual for guidelines on how far you can drive on your spare.
If you replaced your flat with a full-size spare, you can drive normally but should still inspect and/or rotate your tires soon to maintain optimal car performance.
Tips for Changing a Flat Tire Successfully
Changing a flat tire by yourself can feel intimidating, especially if you’re not accustomed to mechanical tasks. Here are several pro tips to ensure you succeed the first time—and every time.
- Dress appropriately: Avoid flimsy shoes and loose clothes that might get in the way of working near the tire or jack.
- Keep a flashlight in your kit: You might find yourself changing a tire at night or in low-visibility conditions.
- Inspect your spare tire regularly: Check the spare’s pressure each time you check your main tires to ensure it’s always ready.
- Don’t over-tighten lug nuts: This can damage threads or make removal at the shop harder.
- Use a torque wrench (if available) for proper tightening following manufacturer recommendations.
Common Mistakes to Avoid When Changing a Flat Tire
Even after following all the steps, mistakes can occur. Avoiding these common ones ensures you complete the task safely.
Mistake 1: Not Checking the Spare Tire’s Air Pressure
A flat spare tire renders all your preparation useless. It’s essential to check the spare’s pressure monthly or anytime before a road trip.
Mistake 2: Removing All Lug Nuts at Once
Doing this can cause the tire to wobble. It’s a best practice to break them loose, then remove only once the vehicle is lifted.
Mistake 3: Improper Jack Placement
Only place the jack under designated structural points. Doing otherwise can damage your vehicle or cause the jack to fail.
Mistake 4: Relying on Impact Tools on the Side of the Road
A cordless impact wrench or air gun might seem ideal, but they’re rarely practical in roadside conditions unless you have power and air sources. Stick with your lug wrench.
Mistake 5: Not Rechecking Tightness After Driving
Drive at low speeds (around 50 mph) for the first few miles, then stop and recheck your lug nuts. This prevents vibrations from loosening them during initial travel.
When to Replace the Spare Tire
Once you’ve successfully completed the tire change, the next question is when to replace the spare. If you had to install a compact “donut” spare tire, this should not be treated as a long-term solution. These tires are designed for limited distances (usually 70–100 miles) and reduced speeds.
Contact a quality tire service center or auto repair shop to get your flat tire repaired or replaced as soon as possible. If the flat tire is beyond repair, replace it with a new standard tire or a new spare to ensure your vehicle is ready for future emergencies.
Preventing Flat Tires: Maintenance and Care Tips
The best tire changes are the ones you never have to do. Being proactive can help you avoid flats altogether. Here’s how:
Regular Tire Checks
- Check tire pressure at least once a month using a reliable tire pressure gauge.
- Ensure tread depth meets the legal minimum of 2/32nds of an inch.
- Inspect tires for cracks, bulges, or embedded objects like nails or glass.
- Rotate your tires every 5,000 to 7,500 miles (depending on your vehicle manufacturer’s suggestion) to ensure even wear.
Driving Habits
- Avoid driving over potholes, curbs, or debris-heavy roads.
- Slow down when driving over rough terrain to minimize impact on tires.
- Monitor alignment by watching for uneven or sudden pulling to one side.
These habits combine for optimal tire health.

What tools do I need to change a flat tire by myself?
To successfully change a flat tire, it’s essential to have the right tools and equipment on hand. These include a spare tire (either a full-size spare or a temporary “donut”), a car jack, a lug wrench or tire iron, and owner’s manual for reference. Some vehicles also come with a wheel wedge or other safety items, which can be helpful. It’s recommended to check these tools periodically to ensure they are in good condition and readily accessible when needed.
Additionally, it’s wise to keep a flashlight (especially for nighttime changes), gloves to protect your hands, and a reflective triangle or hazard lights to increase visibility and safety. A torque wrench is helpful but not essential, and some may prefer having a small blanket or mat to place under the jack for stability. Being well-prepared with these items not only makes the tire change smoother but also enhances your safety while working near the vehicle.
How do I safely position my vehicle before attempting to change a tire?
Before beginning the process of changing a tire, pull your vehicle as far away from traffic as possible and turn on the hazard lights to alert other drivers. Apply the parking brake to prevent the car from rolling while you work. If possible, place wheel wedges or heavy objects in front of or behind the tires opposite the flat one to add an extra layer of security. Avoid changing a tire on a soft shoulder, steep incline, or uneven surface to minimize risk.
The location should also be flat and solid—ideally paved—to ensure the jack functions properly and remains stable throughout the process. If you’re on a hill, it’s preferable to park facing downhill with the front wheels turned appropriately to mitigate risk. Once safely positioned, gather all your tools and keep reflective gear and a phone accessible in case you need assistance. Safety should always come first.
What are the steps for removing the flat tire and replacing it with a spare?
The first step in removing a flat tire is to loosen the lug nuts by turning them counterclockwise using a lug wrench, but do not remove them completely yet. Place the jack under the vehicle at the designated jacking point near the flat tire and raise the vehicle until the tire is off the ground. Now, fully remove the lug nuts and set them aside in a secure place to avoid losing them. Then, pull the flat tire straight off from the wheel base.
Once the flat tire is off, align the spare tire with the wheel bolts and push it onto the hub carefully. Hand-tighten the lug nuts back onto the bolts and secure them in a star or crisscross pattern to evenly distribute the pressure. Lower the vehicle slightly with the jack and tighten the lug nuts further using the lug wrench. Afterward, lower the vehicle all the way, double-check the tightness of the lugs, and ensure the spare tire sits firmly against the ground.
How can I avoid damaging my car while jacking it up?
Using the jack improperly can cause damage to your vehicle or even serious injury, so it’s crucial to read the owner’s manual and follow the manufacturer’s guidelines. The jack should be placed on a level surface and aligned precisely with the car’s recommended jacking point—these are labeled in many owner’s manuals and sometimes marked under the vehicle. Avoid placing the jack under plastic components, exhaust parts, or unsupported areas of the frame to prevent damage.
Never completely raise the vehicle with the jack until the tire is slightly lifted off the ground. Do not place any body parts under the vehicle while it is supported only by a jack. It’s always best to work carefully, double-checking the car’s height and stability before proceeding. The use of jack stands or blocks for additional security is recommended for better safety precautions.
Why should I check the lug nuts again after replacing the flat tire?
After replacing the spare tire, it’s important to check the lug nuts again because vibrations and movement during the jacking and lowering process can cause them to loosen slightly. Even if you tightened them initially, these nuts may need a second turn with the lug wrench while the vehicle is firmly back on the ground. This ensures that the wheel remains securely fastened during driving.
Waiting long after replacing the flat tire without checking the lug nuts can lead to dangerous situations, such as the tire coming off while driving. It’s a best practice to revisit the tightness of the lug nuts once you’ve driven approximately 50 to 100 miles with the spare tire installed. Having properly tightened lugs is crucial to driving safety and preventing further complications.
How do I properly care for and maintain a spare tire?
A spare tire is only useful if it’s well-maintained, so it’s important to regularly inspect its condition. Check the air pressure at least once every six months or before long trips, since most spare tires lose pressure over time. Inspect for cracks, bulges, or signs of damage on the tire itself. Also, confirm that the spare wheel is securely fastened in its designated storage area and that it’s clean and dry to prevent corrosion.
In addition, note the age of your spare tire, especially if it’s a temporary donut. Most spare tires are not meant to last indefinitely and may only be safe for a few years, even if unused. Keep a written reminder of when you last checked your spare tire to ensure regular maintenance. Proper care ensures your spare is ready when needed and helps prevent being caught with multiple problems in the event of another flat.
Are there any special considerations when driving on a spare tire?
When driving on a spare tire—especially a temporary “donut” type—it’s important to adjust your driving habits accordingly. Spare tires are smaller and not built for long distances or high speeds. Most have a recommended maximum speed, often around 50 mph, and should only be used for a limited range, usually up to 70 miles. Avoid aggressive driving, sharp turns, high speeds, or harsh braking to reduce risk.
If you’re using a full-size spare, you still need to be mindful. If the spare is a different size or worn more than the other tires, it can affect traction and handling. Before driving any significant distance, consult the owner’s manual for any specific warnings or instructions related to the spare. Replace the flat tire with a permanent tire as soon as possible and schedule an inspection of the spare’s condition.
