Runflat tyres (RFT) represent the latest in a long line of safety initiatives being made available today. Safety has become something of a catch cry for a society which has become less accepting of the trauma associated with all manner of accidents. The value of developing and adopting new technologies to keep us safe is well recognised. Furthermore, consumers have demonstrated a willingness to pay a premium for safety features they understand. Just as anti-lock brake systems, traction control, stability control and air bags have trickled down from upper models to base models, the very same is expected of RFT.


Bridgestone Runflat Tyres


Technology Behind Bridgestone RFT

Runflat Technology increases the tyre's rigidity and heat resistance so that the tyre can support weight while rotating in a deflated state. Bridgestone's new RFT tyres meet this challenge by combining design, materials and construction changes that optimise the location, shape and physical property of each tyre component. The sidewall is reinforced allowing the tyre to carry the vehicle's weight at zero-pressure.

The bead shape itself is unchanged, so that the Bridgestone RFT tyre is compatible with conventional rims. However, the bundle of bead wires is more substantial, ensuring a secure fit on the rim even at zero pressure, and a special bead filler compound minimises the heat generated in this area.

Run flat tyres for safer driving

With regular tyres, a puncture generally means you lose steering control. It also puts you in added danger while changing the tyre on the roadside. With run flat tyres,* if your tyre gets punctured, there’s no sudden deflation – meaning you can continue driving safely.

This is because the tyre’s thicker sidewall is significantly reinforced and made from heat resistant rubber. It can safely carry the weight of your car for a short period, despite a total loss of air pressure.

Safety First

Even at a moderately high speed and over a long distance – typically 80 km/h for up to 80 km – your vehicle will remain stable and you’ll stay in control. So, you should make it to the next service station without needing to change the tyre. Another advantage is that there’s no need to carry a spare tyre – meaning less weight and more storage space.

While this is an important advance in safety, Bridgestone’s commitment to continuous improvement has now produced the next generation in run flat tyres.

With a thinner side wall plus two new heat suppressing technologies that limit tyre distortion – Nano Pro-Tech™ compound and cooling fins – the result is significantly better ride comfort and safety.

Carry on driving after a puncture

With a reinforced, thicker sidewall, Bridgestone RFTs can safely carry the weight of a car for a short period. Meaning no loss of driving control or subsequent roadside tyre changes.
