RunFlat Tyres
What Are Runflat Tyres?
Runflat tyres are a type of tyre that is designed to allow you to continue driving for a limited distance even after they have been punctured or deflated. Unlike traditional tyres, which require immediate attention when damaged, runflat tyres can maintain their shape and function for a certain period usually around 15 miles at speeds of up to 50 mph (80 km/h).
How Do Runflat Tyres Work?
Runflat tyres feature reinforced sidewalls that are much stiffer than standard tyres. This enhanced sidewall construction supports the vehicle's weight even when the tyre loses air, preventing the tyre from collapsing entirely. This means that, even in the event of a puncture, the vehicle can still be driven to a safe location or a tyre repair shop.
There are two main types of runflat tyres:
Self-Supporting Runflat Tyres: These tyres have strong, reinforced sidewalls that allow them to bear the weight of the vehicle even when there’s no air in the tyre.
Support Ring Runflat Tyres: These tyres have a ring of hard rubber around the inside edge that supports the vehicle if the tyre loses air.
Benefits of Runflat Tyres
Safety: The biggest benefit of runflat tyres is increased safety. They reduce the risk of losing control of the vehicle after a puncture, as the tyre will not deflate completely. This allows you to drive to a safer location without the immediate need to change the tyre on the roadside.
Convenience: With runflat tyres, you don't have to stop immediately after a puncture. This can be particularly helpful in situations where stopping on the side of the road could be dangerous or inconvenient.
No Need for a Spare: Because you can continue driving after a puncture, many cars with runflat tyres don’t require a spare tyre, saving space and weight. This can be especially useful for manufacturers looking to reduce the weight of vehicles and improve fuel efficiency.
Better Handling in Some Cases: Runflat tyres are designed to maintain their shape even when punctured, which can sometimes improve handling and stability, particularly in emergency situations.
Disatvantages of Runflat Tyres
Stiff Ride: The reinforced sidewalls of runflat tyres can result in a firmer ride. This may not be ideal for drivers who prefer a smoother driving experience, especially on rough or uneven roads.
Cost: Runflat tyres tend to be more expensive than traditional tyres, both in terms of initial purchase and replacement costs. Additionally, not all tyre shops carry a wide selection of runflat tyres, which may result in higher fitting costs.
Limited Availability: While more vehicles are being equipped with runflat tyres, they are still not as widely available as regular tyres, so finding replacements might be a little trickier.
Limited Range: While you can continue driving with a punctured runflat tyre, the distance is limited (usually 15 miles). It's important to keep this in mind, as you will need to get the tyre repaired or replaced quickly.
When Should You Replace Runflat Tyres?
If you get a puncture or the tyre loses pressure, it’s essential to get the runflat tyre inspected as soon as possible. Even though the tyre may still allow you to drive, it’s not guaranteed to be safe or fully functional after a puncture. Always have the tyre inspected by a professional to determine whether it can be repaired or needs to be replaced.
Runflat Tyres and Mobile Tyre Services
Given their added complexity and the fact that they often can't be repaired at home, runflat tyres are a great example of how mobile tyre services can be incredibly useful. If you find yourself with a punctured runflat tyre, having a mobile tyre service come to your location and inspect, repair, or replace it can be a real lifesaver.
Conclusion
Runflat tyres offer a range of benefits, particularly when it comes to safety and convenience. While they may not be the right fit for every driver due to their higher cost and stiffer ride, they are certainly an excellent option for those who prioritize peace of mind and the ability to drive to a safer location after a tyre puncture.
