The major positive of run-flat tyres is that they help improve driver safety. Due to the innovative technology used within run flat tyres, roadside changes are a thing of the past.
If you’re using run-flat tyres on your vehicle and get a puncture, the tyre is protected and resists the effects of deflation. This means that your vehicle will be able to be driven at reduced speeds to ensure you get home safe.

Run flat tyres are designed to keep working even after suffering a puncture. So, say goodbye to awkward roadside tyre changes. These tyres allow you to continue driving for 50 miles at 50mph to get home or to a fitting centre.
How do run flat tyres work?
A vehicle is usually supported by the air in its tyres, and once there is a puncture, they collapse. The unique construction of run flat tyres reduces the potential dangers of a tyre blow-out. They have tough rubber inserts which temporarily hold up the weight of your vehicle after a puncture.
This allows drivers additional time, dependant on driving speed, vehicle load and driving conditions, to get to their nearest tyre-fitter.
The materials used to manufacture run flats are similar to conventional tyres, and so wear rates should be comparable. Keeping the correct air pressure in your tyres is the best way to ensure a longer life.
Choosing the best run flat tyres for your car
Make sure you check the safety implications of these tyres and match the correct size, speed rating and load index before fitting these on to your car. These tyres are slightly more rigid as compared to conventional tyres and the service centre may have to use a tyre pressure monitoring system to ensure smooth running once the radials are fitted on to your car.
Fitting run flat tyres to your vehicle
Some cars need only run flat tyres, as the suspension set up of the vehicle differs from a car that requires conventional tyres. It is a good idea to check your car manual before switching original OEM tyres to run flats or vice versa. If you are retrofitting run flat radials to a conventional suspension car, make sure your service centre checks the wheel alignment, braking efficiency, and other parameters before you take the vehicle on the road.
Run flat tyre FAQs
Is my vehicle suited for run flat tyres?
Always consult the vehicle or tyre manufacturer regarding which vehicles are suitable for the fitment of Run Flat tyres. These tyres may only be fitted to vehicles equipped with a tyre pressuring monitoring system (TPMS).
Can I replace my run flat tyre with a conventional tyre?
The fitting of conventional tyres to vehicles originally fitted with run flat tyres will remove the vehicle's run flat capability. They will also have no spare tyre. This could potentially leave the driver immobile in the case of a deflation and could compromise handling of their vehicle.
It is therefore recommended to consult with the vehicle manufacturer or tyre manufacturer before replacing a Run Flat tyre with a conventional tyre on such vehicles.
Can I mix different brands of run flat tyres?
The tread rubber compound used in run flat tyres is generally the same or similar to that used in conventional tyres. Therefore, tyre wear rates between the two tyre types should be similar. It is important to note that the best tyre performance is achieved by maintaining correct inflation pressures for the loads and vehicle's use.
Can run flat tyres be repaired?
In short, no. There’s a good reason for this, however. Due to their reinforced design, secondary damage caused by a puncture can be very difficult to ascertain, meaning that any potential harm to the tyre may be masked by its fortified strength. Due to this, we strongly advise having your run flat tyres replaced rather than repaired.
How long can you drive on a punctured run flat tyre?
Once your run flat tyre sustains a puncture, you’ll usually be able to drive approximately 50 miles at 30-50 mph – ample time to get to the nearest garage. The exact range, however, depends on numerous variables such as your vehicle’s load, weather conditions and driving speed.
Does my car have run flat tyres?
The International Organisation for Standardisation (ISO) developed a universal symbol for run flat tyres - represented by a flat tyre continuing down the road.
