If you have a flat tyre we will help you get moving again as quickly as possible with our simple video instructions on how to repair a tyre:
It's important to note you should never try and change a tyre if your personal safety is at risk. If you aren't confident enough to try to repair the tyre yourself and need assistance, you can call the RAC:
In short, no.
Driving on a flat tyre will lessen your control of the vehicle, cause damage to it and see you hit with three penalty points and a £100 fine for driving a defective car.
The Highway Code states tyres should be inflated to the manufacturer’s specification and if you have a flat tyre you should pull over as soon as it’s safe to do so, to avoid putting yourself and others at risk.
Run-flat tyres have specially reinforced sides which enable you to continue to drive on a puncture, provided you drive at limited speeds and for a limited distance – usually 50 miles maximum.
While you’ll be able to continue driving for a limited amount of time on run-flat tyres they can’t be repaired as easily as regular ones, so you’ll eventually need to buy a new tyre should you experience a puncture.
The first thing that’ll happen is a loss of control over your vehicle, which could put yourself and others at risk. That’s why you should slow down and pull over as soon as it’s safe to do so.
Driving on a flat tyre for long enough could also cause damage to important components of your vehicle – including brake lines, suspension and wheels – which could see you hit with a hefty repair bill.
To help avoid flat tyres, keep a careful eye on your vehicle, checking tyre inflation levels, tyre tread levels and brake pads, as these can all be factors.
You should also avoid driving on roads where you’re more susceptible to picking up a flat tyre. Roads such as those around construction sites where there may be debris like nails and glass shards on the road surfaces, on dirt tracks where there may be hidden rocks jutting out of the ground, or on particularly pothole-ridden roads.
Read our guide on how to report a pothole and claim for damage here.
If you’re driving and you pick up a flat, the first thing you’ll likely notice is your steering feeling funny for no reason or your car slowing down – both of these should be signs you need to pull over and check your tyres.
A full blow-out will mean you hear a thud and a flapping noise alongside any issues with your steering. Pull over as soon as it’s safe to do so and check around your vehicle.
As soon as you think you’ve got a flat tyre you should pull over as soon as it’s safe to do so and check your vehicle for signs of a puncture.
Technically, you may be able continue a little further than this but, not only would this cause significant damage to your vehicle, it puts yourself and other road users at risk as you do not have sufficient control of your vehicle.
Yes, simply follow our video guide above on how to inflate a flat tyre – just remember that you’ll still need to visit a mechanic so that they can replace the damaged tyre.
If your tyre fails to inflate when you’re inflating it, it could be too damaged. If this is the case, use your spare tyre or call RAC breakdown assistance and one of our patrols can help you out.
You shouldn’t drive on a flat tyre at all as this can put yourself and other road users at risk and cause permanent damage to your vehicle.
If your tyre has a slow leak and you have means to inflate it (such as sealant and a compressor) then you should be able to inflate your tyre enough to safely transport you to your nearest garage.

There are a number of reasons why you could have a flat tyre, from worn-out or over-pumped tyres to vandalism. The most likely reason for a flat tyre is a puncture after driving over a sharp object, such as shards of glass or a nail.
If you keep getting flat tyres it could be a sign of an underlying problem with your car, such as a faulty valve stem or a damaged mounting surface of your wheel.
Flat tyres could also be caused by your driving habits, for example driving in areas where there is lots of debris on the road (such as near construction sites) or in off-road locations (if your car is not equipped for off-road driving).
Not necessarily. Tyres should always be set to the pressures recommended in your owner’s manual, and these may not be all set at the same pressure.
For example, some front-wheel-drive vehicles have higher pressures in their front tyres to ensure better weight and braking bias.
Uneven tyre pressure can lead to uneven traction on the road and uneven tyre wear and tear. This can cause problems with stability which could lead to problems on the road.
Remember that only tyres on the same axle need to have the same tyre pressure, so you may well find your rear tyres have a different recommended tyre pressure from your front tyres.
Almost always, no. When it comes to tyre pressure, the maximum is often not the optimum.
Your vehicle will have a recommended pressure range, either in bar or pounds per square inch (PSI). Check your vehicle handbook or the stickers on your bodywork and make sure you use the right pressure for your car.
Putting too much air into your tyres can be just as bad as not putting enough air into your tyres, as it can cause them to wear unevenly and can even lead to blow-outs if they get too hot.
Ensure you don’t over-inflate your tyres by filling them up to within your vehicle’s recommended pressure range, which should be available in your owner’s manual or on a sticker on your car’s bodywork.
There’s no set PSI at which a tyre will definitely explode but generally anything between 150 PSI and 200 PSI could see your tyre blow. Make sure your tyre pressure remains at the safe, recommended level at all times.
Tyre pressure should be checked every week, with air pumped in if the pressure has fallen outside of the recommended range to help keep you safe.
You should always check your tyre pressure when the tyres are cold — i.e. before you’ve made any journeys that day. This usually means after the vehicle has been parked for three hours or driven less than a mile. This is because warm or hot tyres that have recently been driven on may give inaccurate pressure readings.
That largely depends on you. If you pull over as soon as it’s safe to do so when you think you may have a flat tyre, you should be able to limit any lasting damage to your wheel.
However, if you dangerously decide to continue driving you could do lasting damage to your wheel and your vehicle, as well as putting yourselves and other road users at risk.
That depends on where the puncture is. If it’s located in the central part of your tyre it may be possible for a mechanic to carry out a safe and lasting minor repair which will obviously be less expensive.
However, if your tyre is punctured on the side it may not be possible for a quick repair to provide a lasting, safe repair which means you may need to pay out for a new tyre.
