What You’ll Need to Change a Flat Tire
Before you even think about touching your car, make sure you have the right equipment. Most cars come with a standard tire-changing kit, usually found in the trunk. It’s a good idea to familiarize yourself with its contents before you have a flat.
Here’s a breakdown of the essential tools:
- Spare Tire: This is your lifesaver! Make sure it’s properly inflated and in good condition. Check it periodically, not just when you need it.
- Jack: This tool lifts your car so you can remove the flat tire. There are different types, but most cars come with a scissor jack or a bottle jack.
- Lug Wrench: This is used to loosen and tighten the lug nuts that hold your wheel in place.
- Vehicle Owner’s Manual: This is your car’s best friend! It has specific instructions for your make and model, including where to find the jack points and how to operate the jack.
- Wheel Chocks (Optional but Recommended): These are wedges placed against the wheels to prevent the car from rolling. If you don’t have chocks, sturdy rocks or bricks can work in a pinch.
- Gloves (Optional): Changing a tire can be dirty work!
- Flashlight (Optional): Crucial if you’re dealing with a flat at night.
- Tire Pressure Gauge (Optional): To check the spare tire’s pressure.
Step-by-Step Guide to Changing a Flat Tire
Now that you’ve gathered your tools, let’s get to the actual process. Remember, safety is paramount.
Step 1: Find a Safe Location
As soon as you notice a flat tire, slow down gradually and look for a safe place to pull over.
Why it’s important: Driving on a flat tire can damage your wheel rim and make the situation worse. Finding a level, stable surface away from traffic is crucial for your safety and to ensure the jack works correctly. Avoid soft shoulders or inclines if possible.
Action: Turn on your hazard lights to alert other drivers. Pull over as far as you can from moving traffic.
Step 2: Apply the Parking Brake and Use Wheel Chocks
Once you’ve stopped, secure the vehicle.
Why it’s important: This prevents the car from rolling while it’s jacked up. The parking brake engages the rear wheels, and chocks add an extra layer of security.
Action: Engage your parking brake firmly. If you have wheel chocks, place them against the wheel diagonally opposite the flat tire. For example, if your front passenger tire is flat, place chocks behind the rear driver’s side tire.
Step 3: Prepare to Loosen the Lug Nuts
Before lifting the car, you need to loosen the lug nuts.
Why it’s important: If you try to loosen them after the wheel is in the air, the wheel will just spin, making it impossible to get the nuts off.
Action: Remove the hubcap or wheel cover if your car has one (you might need a flathead screwdriver or the flat end of your lug wrench). Place the lug wrench onto a lug nut and turn it counter-clockwise. You might need to use some force. Tip: Use your body weight by stepping on the wrench handle if needed, but be careful not to strip the nut. Loosen each lug nut about a half to a full turn, but do not remove them yet.
Step 4: Position the Jack and Lift the Vehicle
Now it’s time to raise the car.
Why it’s important: The jack needs to be placed at a specific, reinforced point on your car’s frame to safely lift the vehicle without causing damage. Your owner’s manual will show you exactly where these points are.
Action: Consult your owner’s manual to locate the correct jacking point for the flat tire. It’s usually a reinforced metal area on the car’s frame near the wheel. Position the jack securely under this point. Slowly crank the jack handle (or pump it, depending on the jack type) to lift the vehicle. Continue lifting until the flat tire is completely off the ground, with enough clearance to remove it. Important: Never place any part of your body under the vehicle while it is supported only by the jack.
Step 5: Remove the Lug Nuts and the Flat Tire
With the car lifted, you can now remove the flat tire.
Why it’s important: You’ve already loosened the lug nuts, making this step easier. Removing the tire allows you to swap it with the spare.
Action: Finish unscrewing the lug nuts by hand. Keep them together in a safe place (like your pocket or the hubcap) so you don’t lose them. Grip the flat tire firmly with both hands and pull it straight towards you. It might be heavy! Lay the flat tire on its side under the car, near the jack, as an extra safety measure in case the jack fails.
Step 6: Mount the Spare Tire
Time to put on the replacement.
Why it’s important: This replaces your flat tire, allowing you to drive again. Proper alignment is key for safety.
Action: Pick up the spare tire and align the holes in the spare with the wheel studs on the car. Push the spare tire onto the studs until it sits flush against the hub.
Step 7: Replace and Hand-Tighten the Lug Nuts
Secure the spare tire in place.
Why it’s important: This holds the spare tire firmly onto the car. Hand-tightening ensures they are seated correctly before lowering the car.
Action: Put the lug nuts back onto the studs and tighten them by hand as much as you can. Tighten them in a star pattern (tighten one, then the one opposite it, and so on). This helps to ensure the wheel is seated evenly.
Step 8: Lower the Vehicle and Fully Tighten the Lug Nuts
Bring the car back down to the ground.
Why it’s important: You need the weight of the car on the tire to properly tighten the lug nuts. The star pattern ensures the wheel is secured evenly and prevents warping.
Action: Slowly lower the car by turning the jack handle in the opposite direction. Once the tire is firmly on the ground and the jack is no longer supporting the car’s weight, remove the jack. Now, use the lug wrench to tighten the lug nuts as much as you possibly can, again using that star pattern. Give them a good, firm turn.
Step 9: Final Checks and Clean Up
You’re almost done!
Why it’s important: This ensures everything is secure and you’ve tidied up your workspace.
Action: Put the hubcap back on if it fits the spare. Stow the flat tire, jack, and lug wrench back in their proper places in your trunk. Double-check that all lug nuts are tight.
Important Considerations After Changing a Tire
You’ve successfully changed your tire! But your work isn’t quite done.
Spare Tire Limitations: Most spare tires, especially the small “donut” spares, are temporary. They are not designed for long-distance driving or high speeds. Check the tire’s sidewall for speed and distance limitations (often around 50 mph and 50 miles).
Tire Pressure: Ensure your spare tire is inflated to the correct pressure. The recommended pressure is usually printed on the tire itself or in your owner’s manual.
Get Your Flat Tire Repaired or Replaced: As soon as possible, take your flat tire to a professional tire shop. They can assess if it’s repairable or if you need a new one.
Re-Torque Lug Nuts: After driving a short distance (about 50-100 miles), it’s a good idea to have a mechanic check and re-torque the lug nuts on the spare tire to ensure they are still tight. Many tire shops will do this for free.
When to Call for Roadside Assistance
While knowing how to change a tire is a valuable skill, there are times when it’s best to call for professional help.
Unsafe Location: If you cannot find a safe place to pull over, or if you are on a busy highway with no shoulder, it’s safer to call for assistance.
Missing Equipment: If your car is missing a spare tire, jack, or lug wrench, you’ll need help.
Stuck Lug Nuts: If the lug nuts are rusted or stuck and won’t budge, forcing them could cause damage.
Physical Limitations: If you have physical limitations that make it difficult or impossible to change the tire yourself, don’t hesitate to call for help.
Damaged Wheel Rim: If the flat tire has also damaged the wheel rim, it’s best to have it towed.
Unfamiliarity or Anxiety: If you’re feeling overwhelmed or anxious, calling roadside assistance is a perfectly valid option. Many auto insurance policies include roadside assistance.
Frequently Asked Questions (FAQs)
Q1: How long does it take to change a flat tire?
A1: For a first-timer following this guide, it might take anywhere from 20 to 45 minutes. With practice, most people can do it in 15-20 minutes. The biggest variables are how easy it is to loosen the lug nuts and how quickly you can find a safe spot.
Q2: Can I drive on a donut spare tire?
A2: Yes, but with significant limitations. Donut spare tires are smaller and narrower than your regular tires. They are designed for temporary use only. Always check the speed and distance restrictions printed on the spare tire or in your owner’s manual. Driving too fast or too far on a donut can damage your car’s drivetrain and braking systems, and it compromises handling and stability.
Q3: What should I do if the lug nuts are too tight to loosen?
A3: If you’re struggling to loosen the lug nuts with the lug wrench, first ensure you are turning it counter-clockwise. If they are still very tight, try using your foot to apply more steady pressure on the wrench handle, but be careful not to slip. Sometimes, a bit of penetrating oil (like WD-40) applied to the lug nuts can help loosen rust, but allow it to soak for a few minutes before trying again. If they still won’t budge, it might be safer to call for roadside assistance to avoid stripping the nuts or damaging the studs.
Q4: Where can I find my car’s jacking points?
A4: Your car’s owner’s manual is the definitive source for jacking point locations. Generally, they are reinforced areas on the vehicle’s frame, often indicated by small notches or specific markings near each wheel. Using the wrong jacking point can cause serious damage to your car’s body or frame.
Q5: What is the star pattern for tightening lug nuts?
A5: The star pattern, also known as a cross pattern, is the sequence in which you tighten lug nuts to ensure the wheel is mounted evenly and securely. After hand-tightening all lug nuts, you tighten them in a pattern where you tighten one nut, then move to the nut directly across from it, then the next nut to the side, and then the one across from that, and so on. This alternating pattern prevents the wheel from being pulled unevenly onto the hub.
Q6: How do I know if my spare tire is properly inflated?
A6: The recommended tire pressure for your spare tire is usually printed on a sticker on the spare tire itself or in your vehicle’s owner’s manual. You can check the pressure using a tire pressure gauge. If it’s low, you’ll need to inflate it at a gas station. It’s a good practice to check the spare tire’s pressure every few months, even if you haven’t had a flat, to ensure it’s ready when you need it.
Q7: Do I need to replace my flat tire, or can it be repaired?
A7: Whether a flat tire can be repaired depends on the location and severity of the damage. Minor punctures in the tread area can often be repaired by a professional tire shop. However, damage to the sidewall or larger punctures are generally not repairable and require replacing the tire. It’s always best to have a professional inspect the tire to determine if it’s safe to repair.
Conclusion
Dealing with a flat tire might seem intimidating at first, but by following these steps, you can confidently handle this common roadside issue. Remember to prioritize safety by finding a secure location, using your parking brake and wheel chocks, and consulting your owner’s manual. Knowing what tools you need and understanding why each step is important will make the process much smoother. Don’t forget that spare tires are temporary solutions, so get your flat tire checked and repaired or replaced as soon as possible. With a little preparation and this handy guide, you’ll be back on the road in no time, feeling empowered and ready for whatever the road throws your way!
