What are run flat tyres?
Run flat tyres are designed to allow cars to be driven safely in the event of a puncture for around 50 miles at a reduced speed of up to 50mph. The exact distance you can safely travel following a puncture to a run flat tyre can vary depending on the tyre manufacturer and various other factors including the number of people travelling in the vehicle. It is best to check your owner’s handbook for accurate ‘run on flat’ distances for your car.
Unlike regular tyres, they incorporate a significantly strengthened sidewall and are designed to be self-supporting so that in the event of a puncture, they can continue to function with reduced or even zero pressure.
Over the past decade the number of car manufacturers who have designed their vehicles with run flat tyres in mind has greatly increased. The majority of BMW and Mini vehicles are now fitted with run flat tyres as original equipment.
Run flat tyres work in conjunction with a Tyre Pressure Monitoring System (TPMS). Run flat tyres are designed to minimise the difference in ride quality when a tyre is punctured. For this reason it is difficult to determine that a tyre has lost pressure or is operating at zero pressure conditions. Without TPMS you could be unaware of a loss of pressure and might exceed the safety limit speed imposed by the manufacturer. This would eventually cause the tyre to fail.
The benefits of run flat tyres
Most motorists will, at one time or another, suffer the inconvenience of a puncture. In order to continue with their journey they will usually have to replace the damaged tyre with the spare wheel or utilise the tyre sealant and inflator pack provided by the car manufacturer to carry out a temporary repair. This can cause delay and distress to some drivers, who may require the assistance of a breakdown service.
This is where run flat tyres are beneficial. If you experience a puncture, run flat tyres allow you to continue to drive, offering plenty of time to move the vehicle to a suitable place to either repair or replace the punctured tyre. Along with saving drivers a great deal of hassle, they also have the following other benefits:
- No need to change a wheel at the roadside | There are inherent dangers associated with changing a wheel at the roadside, particularly if the puncture occurs on a motorway where the work has to be carried out on the hard shoulder. If you are travelling in an isolated area or late at night, being stranded or having to change a wheel in the dark is a risk that most would wish to avoid
- Keep control of your vehicle | Whilst a puncture is usually more of an inconvenience and unwanted expense, the dangers involved with a tyre failure at high speed are far more serious. The greatest danger is the loss of control of the vehicle. This occurs when the sidewall of the tyre, which is usually kept secure against the rim by the internal air pressure, becomes separated from the rim flange and drops into the well of the wheel. This does not happen to run flat tyres
- No spare wheel in the boot | Run flat tyres mean there is no need for a spare wheel in the boot of your car. By removing this, cars with run flat tyres benefit from more boot space and a reduction of the overall weight of the vehicle, resulting in better fuel efficiency
