Step-by-Step: How to Change a Flat Tyre


Step 1: Pull Over Safely


  1. Move your vehicle to a flat, stable surface away from traffic.

  2. Turn on your hazard lights immediately.

  3. Apply the handbrake.

  4. Put the car in Park (automatic) or first gear (manual).

Safety first: avoid changing a tyre on a slope, in traffic, or on soft ground. If unsafe, call roadside assistance.


Step 2: Prepare Your Equipment


Make sure you have:


  • Spare tyre (full-size or space saver)

  • Jack

  • Wheel brace / lug wrench

  • Owner’s manual

  • Gloves

  • Wheel chocks (highly recommended)

Keep these in the boot and check them regularly for readiness.



Step 3: Loosen Wheel Nuts Before Jacking


  • Use the wheel brace to loosen the wheel nuts slightly.

  • Do not remove them completely yet — the car is still on the ground.

This ensures safety and prevents the wheel from spinning.



Step 4: Position the Jack


  • Consult your owner’s manual for correct jack points.

  • Place the jack on firm, flat ground.

  • Make sure the jack is stable and perpendicular to the car body.

Incorrect placement can bend the chassis or cause the vehicle to slip.



Step 5: Lift the Vehicle


  • Pump the jack until the flat tyre is off the ground completely.

  • Ensure stability before removing the wheel.

  • Never place your body under a jacked vehicle.



Step 6: Remove Wheel Nuts and Flat Tyre


  • Fully remove the loosened wheel nuts.

  • Carefully pull the flat tyre straight off the hub.

  • Place it safely out of the way.

Tip: wheel nuts may be very tight; use slow, steady pressure rather than jerking.



Step 7: Install the Spare Tyre


  • Align the wheel holes with the hub studs.

  • Push the spare tyre onto the hub completely.

  • Hand-tighten the wheel nuts in a star pattern.

Do not fully tighten until the tyre is back on the ground.



Step 8: Lower the Vehicle


  • Slowly lower the jack until the tyre touches the ground.

  • Remove the jack.

  • Fully tighten the wheel nuts in a star pattern for even pressure.



Step 9: Check Tyre Pressure

  • Many spare tyres, especially space savers, require higher pressure than normal tyres.

  • Use a pressure gauge to check and inflate if necessary.

  • Improper pressure can cause poor handling or tyre damage.






Types of Spare Tyres in NZ


Full-Size Spare


  • Same as regular tyre

  • Safe for extended driving



Space Saver (Temporary Spare)


  • Smaller, lighter for emergencies

  • Usually limited to 80 km/h and short distances

  • Replace with a full-size tyre ASAP

Check the tyre sidewall for specific speed and distance limits.


Legal Requirements for Tyres in NZ


  • Spare tyres must be roadworthy and safe

  • Must comply with WOF requirements

  • Temporary spares should follow manufacturer speed and distance limits

Driving outside these limits can invalidate your insurance in an accident.


Common Causes of Flat Tyres


  • Punctures (nails, screws, glass)

  • Worn tread or old tyres

  • Incorrect tyre pressure

  • Damaged valve stems

  • Hitting potholes, kerbs, or road debris



Troubleshooting Common Problems



1. Stuck Wheel Nuts


  • Apply penetrating oil

  • Tap gently with a mallet

  • Avoid excessive force; call a mechanic if stuck



2. Jack Won’t Lift Car


  • Ensure proper placement on solid ground

  • Use a wooden block if safe to increase stability



3. Vehicle Moves Slightly


  • Always use wheel chocks

  • Never work under an unstable vehicle



4. No Spare Tyre


  • Some cars come with a tyre repair kit

  • Follow kit instructions or call roadside assistance



Tyre Replacement Costs in NZ


  • Budget tyre: $120–$180

  • Mid-range: $180–$300

  • Premium: $300+

  • Fitting & balancing: $20–$40 per wheel

Driving on a damaged tyre increases repair and replacement costs.

Tyre Maintenance Tips for NZ Drivers


  • Check tyre pressure monthly

  • Rotate tyres every 10,000 km

  • Inspect tread and sidewalls regularly

  • Keep spare tyres inflated

  • Maintain gloves, jack, and wheel brace in good condition

Regular maintenance prevents roadside emergencies and WOF failures.
