Run-flat tyres, also known as self-supporting tyres or zero-pressure tyres, are a type of tyre designed to continue functioning even after a puncture. Unlike traditional tyres, run-flat tyres have reinforced sidewalls that allow the vehicle to continue driving for a limited distance and at a reduced speed.
History of Run Flat Tyres
The invention of run-flat tyres can be traced back to the 1930s, but it wasn’t until the 1980s that the technology was refined and commercialized. Today, run-flat tires are a popular option for drivers who value the convenience and peace of mind of not having to change a flat tyre on the side of the road. Most luxury car owners opt for run-flat tyres as they are very expensive compared to regular tyres and because of this brands also make run-flat tyres for high-end cars only.
How Run Flat Tyres Work
Run-flat tyres are designed to continue functioning even after a puncture. Unlike traditional tyres, run-flat tyres have reinforced sidewalls that can support the weight of the vehicle in the event of a puncture. This allows the driver to continue driving at a reduced speed for a limited distance, usually around 80 to 120 kilometres, to reach a safe location for repair or tyre change.
The design of run-flat tyres is crucial for ensuring that they continue to work after being punctured. In the case of a puncture, the strengthened sidewalls of run-flat tyres are intended to hold the weight of the car, keeping the tyre from collapsing and allowing the driver to keep going.
Run-flat tyres are made to keep running even after being punctured. Run-flat tyres, in contrast to traditional tyres, feature sidewalls that have been strengthened to carry the weight of the car in the case of a puncture. This enables the driver to continue driving for a short distance—typically between 80 and 120 kilometres—at a slower pace to go to a safe spot for maintenance or tyre replacement.
Benefits of Run-Flat Tyres
Run-flat tyres are a type of tyre designed to continue functioning even after a puncture, providing several benefits for drivers. Some of the key benefits of run-flat tyres include:
- Enhanced safety: The increased safety that run-flat tyres offer is one of their main advantages. A puncture in a set of standard tyres can result in a sudden loss of tyre pressure and a loss of control of the vehicle. Run-flat tyres provide the driver extra time to react and safely halt.
- Convenience: Not needing to carry a spare tyre or tyre-changing tools is another advantage of run-flat tyres. This can free up room in the trunk and lighten the load on the car as a whole.
- Reduced road hazards: Road hazards are decreased since run-flat tyres lessen the chance of leaving a damaged tyre on the road, which might be dangerous for other motorists. This is because run-flat tyres may be used after a puncture, enabling the driver to go to a secure area for repair or tyre replacement.
- Better Performance: Run-flat tyres are designed to handle and perform better than standard tyres. This is due to the fact that contemporary technology, such as reinforced sidewalls and distinctive tyre designs, enhances grip and stability on the road.
Considerations When Using Run-Flat Tyres
Run-flat tyres are a type of tyre designed to continue operating even after a puncture, offering various advantages to drivers. However, there are significant factors to consider while utilising run-flat tyres. Among the major concerns are:
- Cost: Run-flat tyres are more expensive than regular tyres, and the cost can vary significantly depending on the tyre brand, size, and performance level.
- Availability: Run-flat tyres may not be available in all sizes, and the availability may vary based on the brand and model of your vehicle.
- Driving distance and speed: Run-flat tyres are designed to provide temporary support and mobility in the event of a puncture, allowing the driver to continue driving at a reduced speed for a limited distance.
- Performance: Run-flat tyres are designed to provide improved handling and performance compared to regular tyres.
- Compatibility with your vehicle: Run-flat tyres are not made for every vehicle size as tyres are highly expensive and only luxury car owners tend to buy RFT tyres. Tyres may not be compatible with all vehicles, and it’s important to check with the manufacturer or a tyre specialist to ensure that run-flat tyres are suitable for your vehicle.
- Tread life: The tread life of run-flat tyres is shorter compared to regular tyres due to the additional weight and construction required for the reinforced sidewalls.
