The steering wheel tugs to one side, something starts thumping under the car, and your stomach drops. A flat tyre while driving feels like an emergency, and how you handle the first few minutes matters more than the repair itself.
This guide takes you through getting to safety first, deciding whether to change the tyre yourself, and what to do once you are rolling again. If you would rather not touch a jack at all, we also show how Driveo's on-site tyre change works.
Key Takeaways
Safety comes before the tyre. Take a few extra seconds to reach a spot where you can stop without being in anyone's path, even if that means rolling slowly for a short distance.
A flat tyre pulls the car toward the damaged side. Keep both hands on the steering wheel, lift off the accelerator and let the car lose speed before you brake lightly.
Do this straight away so drivers behind you know something is wrong. Then steer for the emergency lane, a layby or a quiet side road, and avoid bends and blind spots where traffic only sees you at the last second.
Exit through the passenger side if you can, and wear a reflective vest if you keep one in the car. On a highway, MIROS advises all passengers to wait outside the road barrier rather than sitting in the stopped car.
Set the triangle behind your car before you call for help. MIROS recommends at least 30 m, while The Motorist's highway breakdown guide suggests 50 to 100 m, so lean toward the longer distance on a fast road. With no triangle, keep the hazards on and raise the bonnet.
On a highway, call the operator's hotline (PLUS runs 1-800-88-0000) or 999, and use the SOS phones that sit roughly every 2 km. If the situation keeps getting worse, our highway breakdown checklist covers what else to do while you wait.
You can, but only on firm, flat ground well away from moving traffic. On a highway, leave the tyre alone and call for help.
MIROS has said it is dangerous to repair a car or change a tyre in the emergency lane, especially at night, after motorists were killed doing exactly that. A tyre can be replaced, and you cannot.

If you are somewhere safe but do not want to do the job yourself, you can book Driveo's on-site tyre change service and a technician comes to you. It is open to any driver, with no insurance policy required and no claim to file.
Open the Driveo app, tap View All, pick tyre change, and enter your vehicle and contact details. Submit the request, and once Driveo confirms it you can wait somewhere safe for the technician. You pay after the service is done.
Service runs 24/7 across covered areas in Peninsular and East Malaysia, including Kuala Lumpur, Selangor, Johor Bahru, Penang, Langkawi, Melaka, Sabah, Sarawak and Perlis. Most confirmed requests are fulfilled within 45 to 90 minutes, and the technician contacts you on WhatsApp. That wait is a good reason to get to a safe spot first and book from there.
Some flats cannot be fixed at the roadside. If you have no usable spare or the wheel is stuck, you can book a car towing service instead and have the car taken to a tyre shop. All of our roadside assistance services sit in one place if you need something else along the way.
Only start once the car is on a safe, flat spot. Have the spare, jack, wheel brace and your owner's manual ready, and check the manual for the correct jacking points. The method below follows the AA's guide to changing a tyre.
Switch off the engine, keep the hazard lights on and apply the handbrake. Leave an automatic in park, or a manual in first gear.
Do this while the wheel is still on the ground, because it is far easier than fighting the nuts once the tyre can spin. Use the locking nut key first if your car has one, then turn each nut slightly anticlockwise with the wheel brace. Do not remove them yet.
Find the marked jacking point closest to the flat tyre and clear away any stones. Set the jack on firm, level ground and raise the car until the flat clears the ground with room for the inflated spare. Keep checking that the jack stays upright, and keep every part of your body out from under the car.
Take the nuts off, keep them together on a clean surface, and pull the wheel straight off. If it is stuck, do not force it. Refit the nuts and call for help.
Line up the holes, slide the spare on and hand-tighten the nuts in a diagonal pattern.
Lower the jack until the tyre just touches the ground, then tighten the nuts firmly, again in a diagonal pattern. Lower the car fully, take the jack away and avoid overtightening.
Check the spare's pressure against the figure in your handbook, then stow the flat tyre, jack and brace securely. If the spare is a space-saver, it carries a speed limit, usually around 80 km/h, so read the sticker on the wheel. Have the nuts rechecked and the damaged tyre dealt with as soon as you can.
A puncture in the tread can often be repaired, while sidewall damage cannot. A tyre shop makes the final call, but it helps to know what they will check.
According to Continental's tyre repair guide, repairs are only allowed in the central three-quarters of the tread. The puncture must also be under 6 mm across, and the tyre cannot be cracked, worn past the 1.6 mm limit or showing cords.
The sidewall flexes constantly and carries heavy loads, so a patch there is unlikely to hold. A tyre with structural damage or an old, faulty repair also has to go.
Driving on a deflated tyre can pinch the sidewall between the rim and the road and spread the damage beyond the repairable area. If you rolled a distance on the flat, tell the shop so they inspect it properly before deciding.
Your next step depends on where you stopped. On a highway, switch on the hazards, get everyone behind the barrier and call the patrol or 999. On a quiet street or in a car park, you can change the tyre yourself with the steps above, or book Driveo's tyre change service from the app and wait somewhere safe.
If the spare is missing or the wheel will not come off, book a tow instead and let a tyre shop take over. Keeping the Driveo app on your phone means all of these options are a few taps away the next time a tyre goes.
