Introduction
A flat tyre can happen at any time. Whether caused by a nail in the tread area, low tyre pressure, or a sudden blowout, it can quickly turn a routine journey into a stressful situation. Knowing what to do when you have a flat tyre on the road is essential for your safety, your passengers, and your vehicle.
This guide breaks down exactly what to do, step by step, so you can stay safe and get back on the road quickly. It also outlines when to handle it yourself and when to call in skilled technicians for professional roadside service.
Step 1: Pull Over Safely and Stay Aware
As soon as you notice a flat tyre, unusual steering, or your tyre pressure monitoring system alerts you:
- Slow down gradually
- Avoid sudden braking or sharp turns
- Pull over to a safe location away from traffic
- Choose flat, stable ground where possible
Once stopped:
- Turn on your hazard lights
- Engage the handbrake
- Ensure passengers exit the vehicle safely if required
Safety always comes first. A damaged tyre increases the risk of losing control, especially at speed.
Step 2: Inspect the Tyre and Identify the Issue
Carefully check the affected wheel:
- Look for visible puncture signs such as a nail or screw
- Check if the tyre is completely flat or partially inflated
- Inspect the tread and sidewall for cracks or splits
- Check if the wheel rim has been damaged
Common causes include:
- Tyre puncture in the tread area
- Blowout due to pressure loss
- Sidewall damage which is not repairable
If the damage is severe, do not attempt to drive further. This can lead to costly repairs and unsafe driving conditions.
Step 3: Decide Your Next Move
You now have three main options depending on your situation:
Option 1: Change to a Spare Tyre
If you have a spare tyre and the necessary tools:
- Jack
- Wheel wrench
- Secure ground positioning
Follow this process:
- Loosen the wheel nuts slightly before lifting the vehicle
- Use the jack to raise the car
- Remove the damaged tyre
- Fit the spare tyre and hand tighten
- Lower the vehicle and tighten firmly in a star pattern
Important:
- Drive at reduced speed and follow the maximum speed recommended for your spare tyre
- Temporary spare tyres are not designed for long distances

Option 2: Use a Tyre Repair Kit (Temporary Fix)
Some vehicles are equipped with tyre repair kits instead of a spare tyre.
These can:
- Temporarily seal a puncture
- Reinflates the tyre
However:
- Not suitable for large punctures or sidewall damage
- Only a short-term solution
You should still arrange a proper repair or replacement as soon as possible.
Option 3: Call Roadside Assistance (Recommended)
If you are:
- On a busy road
- Unsure how to change a tyre
- Lacking tools or equipment
- Dealing with a dangerous situation
The safest option is to call professionals.

Step 4: Repair or Replace the Tyre
Once you are safe, the next step is resolving the issue properly.

When a Tyre Can Be Repaired
- Small puncture in the tread area
- No structural damage
- Within compliance standards
When a Tyre Must Be Replaced
- Sidewall damage
- Large puncture
- Severe wear or damage
- Compromised performance
Driving on a damaged tyre increases risk and can affect your steering, braking, and overall vehicle safety.
Step 5: Get Back on the Road Safely
Before continuing your journey:
- Ensure all wheel nuts are tightened correctly
- Check tyre pressure
- Confirm the vehicle is stable
- Drive cautiously and avoid high speeds
If you are using a spare tyre, visit a repair service as soon as possible.
