What to Do If You Get a Flat Tyre

Getting a flat tyre is one of those driving experiences that catches you completely off guard. Whether it happens on a quiet residential street in Oxford or on the A34 during rush hour, knowing what to do can make the difference between a minor inconvenience and a dangerous situation.

Step 1: Stay Calm and Slow Down Gradually

The moment you notice something feels wrong — a pulling sensation, a thumping sound, or your steering becoming heavy — do not slam the brakes. Instead, ease off the accelerator gently and allow the car to slow down naturally. Sudden braking on a flat tyre can cause you to lose control of the vehicle.

Step 2: Find a Safe Place to Stop

Switch on your hazard lights immediately to alert other drivers. Look for a safe, flat area to pull over — a lay-by, car park, or wide section of road. Avoid stopping on a bend, the brow of a hill, or anywhere with poor visibility. If you are on a motorway, try to reach the hard shoulder or, ideally, an emergency refuge area.

Once you have stopped, keep your hazard lights on and, if it is dark or visibility is poor, switch on your sidelights too.

Step 3: Make Yourself Visible

If you have a high-visibility vest, put it on before exiting the vehicle. Place a warning triangle at least 45 metres behind your car on a single carriageway road. On a motorway, do not attempt to place a warning triangle — it is too dangerous with fast-moving traffic.

Step 4: Assess the Damage

Take a careful look at the affected tyre. You are looking for:

• A nail, screw, or sharp object — if one is embedded in the tread, leave it in place. Removing it will cause the tyre to deflate faster.
• Sidewall damage — any cuts, bulges, or tears in the sidewall mean the tyre cannot be repaired and must be replaced.
• Complete deflation — if the tyre is completely flat and sitting on the rim, you will need a replacement rather than a repair.

Step 5: Decide Your Next Move

You have a few options depending on your situation:

• Use the spare tyre — if you have a spare and feel confident changing it, this is a good option in safe conditions. Make sure the spare itself is properly inflated.
• Use a tyre inflation kit — many modern cars come with a sealant and compressor kit instead of a spare. These work for small punctures in the tread but will not help with sidewall damage or large tears.
• Call for professional help — if you are on a busy road, in the dark, unsure about the damage, or simply not comfortable doing it yourself, calling a mobile tyre fitting service is always the safest choice.

Step 6: Avoid Driving on a Flat Tyre

It can be tempting to limp to the nearest garage, but driving on a flat tyre — even a short distance — can cause serious damage to the wheel rim, brake components, and suspension. What starts as a simple puncture can quickly become a far more serious problem.

When to Call a Professional

A qualified technician will assess the damage and either repair or replace the tyre on the spot.

Prevention Tips

While you cannot prevent every flat tyre, regular checks go a long way:

• Check your tyre pressures at least once a month
• Inspect your tyres for embedded objects, cracks, and uneven wear
• Avoid potholes and kerbs where possible
• Replace tyres before they reach the legal minimum tread depth of 1.6mm

Frequently Asked Questions

Can I drive to a garage on a flat tyre?

It is not recommended. Driving on a flat tyre can damage the wheel rim, brake disc, and suspension components. If you cannot safely change the tyre yourself, it is best to call a mobile tyre fitting service to come to you.

How long does it take to fix a flat tyre?

A professional can typically repair a puncture in around 20 to 30 minutes. A full tyre replacement takes a similar amount of time. NN Mobile Tyres usually arrives within 30 to 45 minutes across Oxford and Oxfordshire.

Safety is the priority. Turn on your hazard lights, move to a well-lit area if possible, and stay inside the vehicle with doors locked until help arrives. NN Mobile Tyres operates 24/7, so you can call or WhatsApp at any time of day or night.
