The stronger forces take their toll on the material. The bikes have a massive amount of torque and are far heavier. In order to be able to make any use of the bikes' potential, it requires a lot more grip. An improved durability is also required in order to be able to withstand the increased stresses. The new, high-quality silica compound has been developed to cope with extreme stresses, and can meet both requirements as a result.
Two additional layers of fabric – a layer from bead to bead as well as a further layer under the tread – ensure the significantly increased stability that is also required, as well as providing improved puncture protection. They support the entire structure and offer increased protection for the side walls of the tyres and against puncturing.
