What is a run flat tyre?
A run-flat tyre is a type of tyre designed to allow a vehicle to continue driving even after a puncture or loss of air pressure https://www.theaa.com/driving-advice/safety/run-flat-tyres
Also known as a self-supporting tyre, they can be used only for short distances.
Get the tyre renewed or repaired as soon as possible.
Unlike conventional tyres, run-flat tyres are constructed with reinforced sidewalls that can support the weight of the vehicle even when the tyre is deflated.
Here are some key features and benefits of run-flat tyres:
- Reinforced Sidewalls: Run-flat tyres have specially reinforced sidewalls to support the tyre in a deflated condition.
Consequently they provide support and maintain the structural integrity of the tyre even when there is a loss of air pressure. This allows the vehicle to continue driving. However they must be used at reduced speeds and for a limited distance.
- Temporary Mobility: Run-flat tyres enable a driver to continue driving to a safe location, such as a service station or tyre repair shop, without immediately changing the tyre. Additionally there is no need to use a spare tyre. This can be helpful where changing a tyre may be difficult or unsafe. Such situations include being on a busy road or in bad weather.
- Safety: Run-flat tyres help enhance safety. They reduce the risk of sudden tyre failure and loss of control that can occur when driving on a deflated tyre. They provide additional stability and control. Thus the driver can steer better even with a punctured tyre.
- Convenience: With run-flat tyres, there is no need to carry a spare tyre, jack, or other equipment for immediate tyre changes. This can help free up space in the vehicle. Besides it eliminates the need to deal with a flat tyre on the side of the road.
- Monitoring Systems: Many modern vehicles equipped with run-flat tyres also have a tyre pressure monitoring system (TPMS) that alerts the driver when a tyre has lost air pressure. This early warning system allows the driver to take appropriate action and address the tyre issue promptly.
Crucially run-flat tyres have limitations. They are not designed to be driven on for long distances or at high speeds after a puncture. The recommended distance and speed limitations vary depending on the tyre manufacturer and vehicle specifications.
Recommendations on run-flat tyre use are available in the vehicle owner’s manual. Alternatively seek professional advice on run-flat tyres for a particular vehicle.
