It’s late, it’s raining, and your dashboard has just lit up with a tire warning. Then you feel the car pull to one side. Most drivers think of calling a tow truck at this point. But if you know how to change car tire, you can be back on the road in about 15 minutes without spending a cent.
This guide walks you through the whole job in plain language, from the tools you need to the final check before you drive off. You’ll also learn the mistakes that cause most roadside injuries, and how to do the job safely even if you’ve never touched a jack before.
What You Need Before You Start
Knowing how to change car tire is half skills and half preparation. Check that these items are in your boot or trunk before you need them:
- A properly inflated spare tire (check it every few months)
- A jack (the scissor jack that came with your car works fine)
- A lug wrench (the L-shaped or cross-shaped tool for loosening wheel nuts)
- Your owner’s manual, which shows the exact jack points for your car
- A torch or phone light for dark conditions
- Gloves and a small mat or cloth to protect your hands and knees
- Wheel wedges or a large stone to stop the car rolling
Many people buy a car and never open the spare tire compartment. Do it this weekend. Finding a flat spare or a missing wrench at the roadside is a far bigger problem than the original puncture.
Step 1: Find a Safe Spot and Prepare the Car
Safety comes before speed. As soon as you realise you have a flat, slow down gradually and look for a flat, firm, straight stretch of road. Avoid hills, bends, soft grass and narrow shoulders.
Once you’ve stopped:
- Switch on your hazard lights.
- Apply the handbrake fully.
- Put the car in “Park” (automatic) or first gear (manual).
- Ask passengers to get out and stand well away from traffic.
- Place wheel wedges behind or in front of the tire diagonally opposite the flat.
If you’re on a motorway or a busy road and can’t get far enough from traffic, don’t attempt the job. Drive slowly to the next exit or service area if you can, or call roadside assistance. No tire is worth your life.
Step 2: Loosen the Lug Nuts First
This is the step beginners get wrong most often. When learning how to change car tire, remember this rule: loosen the nuts while the car is still on the ground.
Once the wheel is in the air, it spins freely and you can’t get enough force on the nuts. On the ground, the tire’s grip does the work for you.
- If your wheel has a hubcap, pry it off with the flat end of the lug wrench.
- Fit the wrench onto a lug nut.
- Turn it anticlockwise (remember: “lefty loosey”).
- Loosen each nut about half a turn. Don’t remove them yet.
If a nut won’t budge, place the wrench so the handle is horizontal and press down with your foot, using your body weight. Never jump on it, as that can slip and injure you.
Step 3: Lift the Car With the Jack
Your jack must sit on the correct lifting point, or it can damage the car’s body or slip. Check your owner’s manual, because most cars have a marked spot on the metal frame just behind the front wheel or just in front of the rear wheel.
- Place the jack on solid, level ground directly under the lifting point.
- Raise it until it just touches the car.
- Double-check that it’s positioned correctly.
- Continue raising the car until the flat tire is about 5 to 8 cm (2 to 3 inches) off the ground. You need that gap because the spare will be fully inflated and taller than the flat.
Important safety rule: never put any part of your body under the car, and never start the engine while it’s on the jack.
Step 4: Remove the Flat Tire
Now that the car is lifted, this part is simple:
- Fully unscrew the loosened lug nuts and put them somewhere safe, such as in the hubcap, so they don’t roll away.
- Grip the tire with both hands at the 9 o’clock and 3 o’clock positions.
- Pull it straight toward you and off the wheel studs.
- Lay the flat tire flat on the ground, or slide it partly under the car frame as a backup in case the jack fails.
Tires are heavier than they look, usually 10 to 15 kg (22 to 33 lb), so lift with your legs, not your back.
Step 5: Mount the Spare Tire
Line up the holes in the spare with the wheel studs and slide it on. Check that the valve stem faces outward.
- Push the spare firmly onto the studs.
- Screw the lug nuts on by hand, clockwise, until they’re snug.
- Don’t fully tighten them yet.
A quick note on space-saver (donut) spares: these small temporary tires are designed for short distances only, usually up to about 80 km (50 miles) at a maximum of 80 km/h (50 mph). The exact limits are printed on the tire sidewall, so read them.
Step 6: Lower the Car and Tighten the Nuts
- Lower the jack slowly until the spare touches the ground but the car’s full weight isn’t on it yet.
- Tighten the nuts in a star (criss-cross) pattern, not in a circle. This presses the wheel evenly against the hub and prevents wobbling.
- Lower the car fully and remove the jack.
- Give each nut one more firm tightening with the wrench.
Even tightening matters. A wheel secured unevenly can vibrate at speed or, in the worst case, work loose.
Step 7: Final Safety Checks
Before you pack up, run through this checklist:
- Are all lug nuts tight?
- Is the flat tire, jack and wrench stowed securely in the car?
- Did you collect your wedges and any hubcap?
- Is the spare’s pressure right? Check it at the next petrol station, since many spares sit under-inflated for years.
After driving 50 to 100 km (30 to 60 miles), re-check the lug nuts. They can settle slightly, and a quick re-tighten is cheap insurance.
Common Mistakes When Changing a Tire
Even people who know how to change car tire fall into these traps:
- Jacking up the car on a slope or soft ground, which makes it unstable
- Forgetting to loosen the nuts before lifting
- Using the wrong jack point, which can bend the car’s body
- Tightening nuts in a circle instead of a star pattern
- Driving too fast or too far on a donut spare
- Never checking the spare’s pressure until the day it’s needed
What to Do After You’ve Changed the Tire
A spare is a temporary fix. Get the flat tire inspected as soon as possible. Many punctures from nails or screws can be repaired cheaply, but sidewall damage usually means replacement. Then restore your full-size spare so you’re ready next time.
Frequently Asked Questions
How long does it take to change a car tire?
For a first-timer, it usually takes 20 to 30 minutes. With practice, most people finish in 10 to 15 minutes.
Can I change a tire by myself?
Yes. Most car tires can be changed by one person using the tools in the car. If you have limited strength, a long-handled wrench or roadside assistance can help.
How tight should lug nuts be?
They should be firm and snug, not forced beyond your strength. A typical torque is around 80 to 110 Nm for most passenger cars, but check your manual for the exact figure.
Can I drive far on a spare tire?
It depends on the type. A full-size spare behaves like a normal tire. A donut spare is limited to short distances at reduced speed, so drive carefully to a garage.
What if the lug nuts are stuck?
Try applying firm, steady pressure with your foot on the wrench handle. A little penetrating oil can help. If they still won’t move, call a professional rather than risk stripping the nuts.
Conclusion
Learning how to change car tire is one of the most useful skills a driver can have. It saves money, time and stress, and it keeps you in control when something goes wrong. The process comes down to a few clear steps: stop safely, loosen the nuts, jack up the car, swap the tires, tighten in a star pattern, and recheck.
Your next step: go to your car today, open the boot, and check your spare, jack and wrench. Spend ten minutes there now, and you’ll be glad you did when a flat tire strikes. Found this guide helpful? Share it with a friend or family member who drives.
