A flat tyre can happen anywhere. Knowing how to change it safely can save time and keep you from being stranded. This step-by-step guide explains how to change a flat tyre on most cars.
Key Takeaways
- Move to a safe, flat spot away from traffic before starting.
- Loosen lug nuts slightly before jacking up the car.
- Use the jack only at the manufacturer’s specified points.
- Check the spare tyre pressure regularly so it is ready when needed.
Tools You Need
- Spare tyre (full-size or space-saver)
- Jack
- Wheel spanner / lug wrench
- Wheel lock key, if your car has locking nuts
- Reflective warning triangle
- Torch and gloves
Step-by-Step
- Park on firm, level ground away from traffic. Turn on hazard lights and engage the parking brake.
- Place a warning triangle behind the car.
- Get passengers out and to a safe place.
- Remove the wheel cover if present.
- Loosen lug nuts half a turn anticlockwise while the tyre is on the ground.
- Place the jack at the correct jacking point and raise the car until the tyre is off the ground.
- Remove lug nuts and take off the flat tyre.
- Fit the spare tyre and hand-tighten lug nuts.
- Lower the car and tighten nuts in a criss-cross pattern.
- Store tools and the flat tyre, and check spare tyre pressure soon.
Safety Tips
- Never go under a car supported only by a jack.
- Avoid changing tyres on highways’ fast lanes; call assistance if unsafe.
- Follow speed limits for space-saver spares.
Tubeless Tyre Puncture Kits
Many cars now carry puncture repair kits or sealants instead of full-size spares. These provide temporary fixes to reach a tyre shop. Follow instructions carefully.
Finding the Jacking Points
Every car has specific jacking points, usually marked by notches or reinforced areas along the underside near each wheel. Using the wrong point can damage the car or cause the jack to slip. Check the owner’s manual for exact locations.
Temporary Puncture Repair Kits
- Locate the puncture if possible.
- Attach the sealant bottle to the tyre valve.
- Inflate using the compressor as instructed.
- Drive a short distance to spread sealant.
- Check pressure and visit a tyre shop soon.
Sealant kits work for small punctures in the tread, not for large cuts or sidewall damage.
Tyre Changing Mistakes
| Mistake | Why It Matters |
|---|---|
| Jacking on soft ground | Jack can sink or tip |
| Loosening nuts after lifting | Wheel spins, making it hard |
| Not tightening in criss-cross pattern | Uneven seating |
| Forgetting to recheck nut tightness | Wheel may loosen |
Practice Before You Need It
Practise changing a tyre once at home in a safe space. Knowing where tools are and how they work makes a real emergency much less stressful.
When to Call for Help
- On busy highways with no safe shoulder
- At night in unsafe areas
- If lug nuts are too tight or damaged
- If the spare is flat or missing
Roadside assistance from your insurer, car manufacturer or NHAI helpline can help when conditions are unsafe.
A Real-Life Scenario
Pooja got a flat tyre on a quiet road outside Mysuru at dusk. She had watched a video on changing a tyre but never tried it. She parked safely, switched on hazard lights, placed the warning triangle and followed her car manual. She loosened the wheel nuts before jacking up the car, replaced the tyre and tightened the nuts in a star pattern. It took longer than expected, but she managed safely and drove to the nearest tyre shop.
