Few things disrupt a journey faster than unexpected vehicle trouble. One of the most common and frustrating culprits is a flat tyre. Whether commuting across town or setting off on a weekend getaway, dealing with a tyre replacement or urgent flat tyre repair can throw your plans into disarray. Fortunately, knowing what typically causes a flat can help you stay prepared and avoid needing an emergency flat tyre service altogether. Let’s uncover the top causes of flat tyres and how to fix or prevent them fast.
Top Causes of Flat Tyres
Understanding what causes a deflated tyre is the first step towards prevention. Let’s explore the most common reasons Australian drivers end up with deflated or damaged tyres.
1. Punctures from Road Debris
Punctures are the prominent cause of deflated tyres. Sharp objects like nails, screws, broken glass, or even rocks can lodge into your tyre while driving, especially on poorly maintained roads. If the puncture is deep enough, it can lead to a slow or sudden air loss. A tyre plug or patch might suffice if the puncture is minor and not on the sidewall. Otherwise, consider complete tyre replacement.
2. Damaged Roads and Potholes
Driving through potholes or on rough terrain can damage the tyre’s internal structure or sidewall. Repeated contact with jagged surfaces accelerates wear and increases the risk of flats or blowouts. Drive cautiously in construction zones and constantly scan the road ahead for hazards.
3. Underinflated or Overinflated Tyres
Incorrect tyre pressure affects how your tyres perform. Underinflated tyres create excess friction, which leads to overheating and structural damage. Overinflated tyres can reduce road contact and make tyres more vulnerable to sharp impacts. Regularly check your tyre pressure and ensure it aligns with the manufacturer’s recommended PSI.
4. Worn Tread
Tyres naturally wear out over time. Once the tread depth falls below legal or safe limits (1.5mm in Australia), the tyre is more prone to punctures and skidding, especially in wet conditions. Use a tread depth gauge or the “20-cent coin test” to determine wear. If the tread is worn down, it’s time for a tyre replacement.
5. Extreme Temperatures
Both hot and cold weather can weaken tyre material. High heat causes tyre pressure to rise, increasing the chance of a blowout. Cold weather makes rubber brittle, potentially leading to cracks and air leaks. Park in shaded areas during summer and regularly inspect for signs of dry rot or cracking.
6. Faulty Tyre Pressure Monitoring System (TPMS)
A malfunctioning TPMS might not alert you when your tyres are dangerously underinflated, allowing small leaks to turn into full-blown blowouts unnoticed. Have your TPMS checked during routine vehicle servicing to ensure it functions correctly.
7. Poor Driving Habits
Sudden braking, hitting kerbs, and aggressive driving increase tyre wear and raise the likelihood of unexpected flats. Adopt smooth, defensive driving techniques to protect your tyres and suspension.
8. Accidental Damage
How to Spot a Flat Tyre Early and Stay Safe
Catching a deflated tyre early or knowing how to respond when it happens can significantly affect your safety and vehicle longevity.
Warning Signs of a Burst Tyre
- Sudden pulling to one side while driving
- Loud flapping or grinding noises from the tyre area
- Sluggish handling or increased resistance
- TPMS warning light on your dashboard
- Noticeable sagging in one corner of your car
How to Respond to a Deflated Tyre
- Stay Calm and Pull Over Safely: Avoid slamming the brakes. Slowly reduce your speed and pull over to a safe, level location.
- Turn on Your Hazard Lights: Alert other drivers of your position.
- Use a Spare or Call for Help: If you have a spare tyre and tools, you can attempt to change it yourself. Otherwise, contact an emergency flat tyre service.
- Avoid Driving on a Flat: Driving on a flat damages the suspension and rim, increasing the cost of repairs.

Tyre Care Tips
- Check pressure monthly using a quality tyre gauge.
- Rotate tyres every 10,000 km or six months to ensure even wear.
- Inspect tyres to identify embedded debris, bulges, and fractures.
- Wash your tyres and wheels to prevent material buildup.
- Don't overburden your car beyond the recommended weight.
