What Are Run-Flat Tyres?

Run-flat tyres (RFTs) are an experienced professional type of tyre designed to stay secure even when tyre pressure is at zero, allowing the motorist to keep driving a car rather than stopping to alter a tyre. compare tyres

The benefits associated with run-flat tyres include:

Lowered weight of vehicle. Run-flat tyres work out less heavy than standard wheels and tyres, which would also demand a spare, jack and wheel brace. A vehicle that weighs less means better fuel efficiency.
Fewer materials have to manufacture an RFT, thus, making them more eco friendly. 
There is no need for a free tyre, meaning more room in the boot and a lighter load.
There is absolutely no great difference in performance and ride if a run-flat tyre suffers a puncture, offering you safe handling and cornering and lowering the risk of a major accident.
These systems were mostly created to keep drivers safe, as punctures and blowouts can be dangerous, and consideration for a huge majority of fatal accidents on the road. Aside from security, a flat tyre can become a real inconvenience, adding as well as cost to your journey. Changing a tyre is pretty straightforward, but it often occurs at the most inopportune moment – getting stuck on the side of the motorway or in the pouring rainwater with hungry, tired, loud kids in the rearseat is no fun at all! And trying to change a tyre on the hard shoulder can be dangerous by itself, or even impossible if you are disabled or older.

Many different manufacturers are suffering from their own RFT varieties, and they can vary slightly in how they are constructed, but the basic principles are the same, guaranteeing that the tyre drops remain securely placed on the rim of the steering wheel, no matter whether pressure has dropped.

Tyre inability can be extremely serious, especially at higher speeds. A penetration or blowout can cause loss of control, much increased braking distance and reduced grip. When this occurs, the sidewall divides from the rim flange due to the drop in internal pressure, and drops in to the inner tire. This can cause reduction of control, and, possibly, a major accident.

Run-flat tyres reduce this risk by keeping the tyre beads anchored to the rim flange, even when air inflation (which is what keeps normal tires in place) goes down to zero pressure. Consequently your tyre continually perform safely, meaning you don’t have to stop and change your tyre, or risk a distressing losing control.

Vehicles that come with RFTs often taste unpleasant equipped with a spare tyre, and it is not suggested to repair a run-flat tyre, as they are put under a huge amount of pressure and stress and there could be interior damage that is not visible. This is because an RFT carries the weight of the auto on the extra-strengthened sidewall, as opposed to a pneumatic tyre which carries the weight using the pneumatic a result of the air inside.

Michelin, Goodyear, Dunlop, Bridgestone, Pirelli and Continental all manufacture RFTs, and BMW is the most significant user of run-flat tyres as Original Gear (O/E), ie: providing run-flat tyres as standard. Audi, Chrysler and Ferrari also offer run-flat tyres as O/E on some models.

Any vehicle equipped with run-flat tyres should also include a Tyre Pressure Monitoring System (TPMS) to ascertain whether pressure has been lost, as it may well not be discernible by the in ride. Run-flat tyres are meant to maintain speed, handling and smoothness of driving when a puncture occurs, even on a motorway. A TPMS is essential to alert the driving push to a loss in tyre pressure, otherwise the tyre may be overworked in its emergency express and ultimately cause it to fail too. TPMS works in two other ways – either by a messfühler fixed to the tire, inside the tyre, or utilizing the vehicle’s AB MUSCLES.

Run-flat tyres can probably save you money, some inconvenience by providing you with a secure tyre even if a leak occurs. Many vehicles now have run-flat tyres built in as standard – ask your local tyre more healthy for information on whether these specialist tyres would be suited to your car.
