It is a stressful moment: you feel the steering go heavy, hear a flapping sound, and realise you have a flat. The first question almost everyone asks is, can you drive on a flat tyre to get somewhere safer or to a workshop? The short answer is that you should not, except for a very short, slow crawl to get out of immediate danger. Driving on a punctured tyre causes rapid, expensive damage and is genuinely dangerous.
Here is exactly what happens when you drive on a flat, why it is risky, and the right steps to take the moment it happens.
Can You Drive on a Flat Tyre at All?
In an emergency, you may roll the car a very short distance at walking pace to reach a safe, level spot away from traffic.
Beyond that, you should stop. Continuing to drive on a flat tyre, even for a few kilometres, can destroy the tyre, damage the wheel and put you at risk of losing control. It is never worth pushing on to save time.
What Damage Does Driving on a Punctured Tyre Cause?
A flat tyre has no air to support the weight of the car, so the structure collapses onto the road. Driving on a punctured tyre in this state causes a chain of damage:
• The tyre itself is usually destroyed. The sidewall, which is not designed to carry load, overheats and breaks down within metres, turning a repairable puncture into a write-off.
• The alloy or steel wheel can be bent, gouged or cracked as the metal rim grinds on the road surface.
• Brake lines, sensors and suspension components near the wheel can be damaged by the flailing tyre.
• Wheel speed sensors and the TPMS unit may be torn or knocked out of alignment.
What might have been an affordable puncture repair quickly becomes a new tyre, a new wheel, and possibly further mechanical repairs.
Why Driving on a Flat Tyre Is Dangerous
Beyond the cost, the safety risk is serious. A flat tyre dramatically reduces your ability to steer and brake. The car pulls hard to one side, stopping distances grow, and at any speed the tyre can come apart and cause a sudden loss of control. On a busy Sydney road or motorway, that is a recipe for a crash.
The danger also extends to others around you. Pieces of a disintegrating tyre can fly off and strike following vehicles, and a car that suddenly veers can trigger a chain-reaction collision. This is why the safe choice is always to stop, secure the vehicle and call for help rather than pressing on.
What to Do If You Get a Flat Tyre
Stay calm and follow these steps:
• Ease off the accelerator and do not brake hard. Let the car slow gradually.
• Steer smoothly to the side of the road, onto the flattest, safest spot away from traffic.
• Turn on your hazard lights and, if you have one, set up a warning triangle.
• Get yourself and any passengers to a safe position, well away from passing vehicles.
• Call for help rather than attempting a risky roadside change in a dangerous location.
Rather than risk further damage, call for professional help. Our emergency tyre service comes to you and replaces a destroyed tyre on the spot, while our roadside assistance team can reach you quickly anywhere across Sydney, day or night.
Frequently Asked Questions
Can you drive on a flat tyre in an emergency?
Only for a very short distance at walking pace to reach a safe spot away from traffic. Beyond that, driving on a flat tyre destroys the tyre, can damage the wheel and is dangerous, so you should stop and call for help.
How far can you drive on a flat tyre?
Realistically only a few metres at very low speed to clear immediate danger. The tyre begins breaking down almost immediately, so any meaningful distance risks ruining the tyre, the wheel and nearby components.
Will driving on a flat tyre damage the rim?
Yes. Without air to support the car, the metal rim grinds against the road, which can bend, gouge or crack the wheel. This often turns a simple puncture repair into a far more expensive replacement.
Is a flat tyre always a blowout?
No. A flat can be a slow puncture that deflates gradually, or a sudden blowout. Either way, once the tyre is flat you should stop driving on it and have it assessed or replaced.
What should I do first when I get a flat tyre?
Ease off the accelerator without braking hard, steer gently to a safe spot off the road, switch on your hazard lights, move passengers to safety and then call a mobile tyre or roadside assistance service.
