Green tyres: squaring the circle for manufacturers
Safety, fuel economy, and longevity: for fifteen years, tyre makers have been trying to combine these conflicting performances in order to reach a satisfactory balance. With silica-based rubbers and innovative manufacturing processes, they are now able to offer efficient green tyres.

The green tyre is a real headache for engineers. On one hand, energy losses and heating of the rubber need to be reduced to act on the rolling resistance; on the other hand, tyre surface in contact with the soil needs to be able to rise rapidly in temperature to manage very short braking distances. This is a difficult equation, which involves assembling rubbers with different properties!
No compromise on quality
To reconcile the irreconcilable, a lot of work has been done in laboratories on the rubbers and on the manufacturing processes. Engineers have invented new silica-based materials and are using nanotechnology. The result is that the new generation of green tyres now offer performances comparable to standard tires. In addition, they are also more resistant (25% more mileage on average).
