- EU Tyre Label:
Bridgestone Potenza S007 RFT
Bridgestone developed the Potenza S007 especially for high speed super sports vehicles, requiring extreme levels of lateral force due to their sporty setup. The innovative pattern features rigid pattern blocks for outstanding response and unleashed grip on dry surfaces. The wide outside tread in combination with specially tuned carcass construction provide maximum cornering grip, even under most severe load conditions.

Run Flat Technology
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.
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.
Discover the next generation in RFTs
The reinforced sidewall is engineered using Bridgestone’s new Nano Pro-Tech™ compound. This revolutionary rubber compound optimises the distribution of carbon molecules to minimise the friction between them. This means significantly less heat is generated, helping the tyre to hold its shape, even with a new thinner sidewall.
Stay cool and in control
Bridgestone’s next generation RFTs feature another significant improvement. To suppress heat generation on the outside of the tyre, cooling fins have been added. They disrupt the airflow and direct cool air downwards onto the towards the tyre’s surface. Again, this means less heat and a tyre that holds its shape when it has lost all air pressure.
Since 1st November, 2012 all tyres made after 1st July, 2012 must show the European Tyre Label.
The European Union has developed this new provision to promote economic and ecological efficiency and ensure road safety.
Disadvantages The Tyre Label can provide an overview and give the customer more transparency, but it only covers three criteria. For an extensive evaluation of a tyre, however, far more performance characteristics are relevant. Especially in the search for suitable winter tyres the test results from different test institutions such as the ADAC are much more stringent.
We'd like to point out that it is the manufacturer that labels the tyre and provides us with this information. If you do not find the label values, either the manufacturer did not inform us of the label, or the product was manufactured before July, 2012. Before that date, tyres had not yet been required to carry a label, so in some cases it is possible to purchase a tyre without a Tyre Label.
The tyres are classified in terms of three performance characteristics:
• Fuel Efficiency (letters A to G)
• Wet Grip (letters A to G)
• External Noise
Finally, it is the driver that determines the fuel consumption. In order to reduce this over the long-term, by being careful during acceleration drivers can become more fuel-efficient and environmentally conscious.
Regularly checking tyre pressure helps to improve rolling resistance, reduces energy loss, and supports optimum adhesion in wet conditions. To reduce the risk of accidents and ensure your and the safety of other road users, always keep a reasonable distance.

The classification in terms of fuel efficiency is divided into seven classes, from the A-class (the highest) to G-class (the lowest). A tyre in the A-class consumes 0.1 litres less at 100km than a tyre in the B-class. An essential component for fuel efficiency is the rolling resistance or rolling friction.
Rolling resistance is the force that opposes motion. It is formed, for example, when a wheel is rolling. Rolling resistance depends not only on the geometry but also on the properties of the material.
Average Average value is between C-E. Class D is not used.
It shows how efficient the vehicle can brake on wet roads. Wet grip is an important feature especially with summer tyres. Class A has the highest safety and the shortest braking distances. Class F has low security and the longest braking distance.
The wet grip classes are based on test driving on wet roads with a speed of approximately 80 km/h. The difference between the braking distance of the tyres is 3-5 feet per grade. E.g., the difference in braking distance between Class A and Class F are up to 18 metres.
Average The average value of the tyres is between class B-E. Class D and G is not used.
The symbol indicates the external rolling noise in decibels and as a 3 class sound wave symbol to clarify whether the tire can keep the recommended level. External rolling noise does not correspond to tyre noise inside the compartment.
A continuous sound level above 80 decibel can cause health problems.
Three sound waves symbolize the worst results. These are the tyres that exceed the maximum limit of approval. A symbol of 2 sound waves have noise level that corresponds with the approved sound level. Tyres that are marked with 1 sound wave are over three decibel quieter than the approval.
The exact size of a tyre can be found on its sidewall.
The following chart shows you how to read a tyre size.
2. The height as the ratio between the width and the height in %
3. Construction type: "R"= radial (often seen), "D" or "-"= diagonal (rarely seen)
4. The required rim diameter (in inches) for this tyre
5. Load index
