Tyre Construction

A closer look at Metzeler technology

Bias tyre

Also known as conventional or cross-ply tyre. The structure of this tyre is made of a carcass where depending on the different speed and load specifications, two or more layers are overlapped. Each layer is made of textile cords coated into rubber and the overlap angle is designed in order to give the tyre the required dynamic characteristics.

Bias-belted tyre

The structure of this type of tyre consists a conventional carcass and a belt made of two or more crossed layers. The diffe- rence between carcass and belt is given by the different objectives that they have to reach and consequently the different materials that are used: the belt is generally made from an aramid fibre and it’s function is reduce the dynamic deformation caused by centrifugal forces (reduce tyre "growth" at high speed), while the carcass has to mainly give the tyre its stiffness and load carrying capacity.

Belted tyre with radial carcass

The main difference of the bias-belted tyre is given by the structure of the carcass that in this case is radial. This means that its cords are wrapped radially around the tyre, from one bead to the other. In this way low-section tyres can be realized, giving big advantages in terms of cornering stability, reduced weight and high-speed performance. It has extremely high rigidity allowing the possibility to tune the belt winding spacing to produce varying levels of stiffness from shoulder to crown.

 

0° steel belt tyre with radial carcass

Patented Metzeler technology for front and rear tyres utilising a radial carcass and a single layer belt made of steel cord. If you think of the rolling direction of the tyre, the belt is wound circumferentially around the carcass giving an angle of almost 0°. The advantages of using steel are its extremely high rigidity and the possibility to tune the winding spacing allowing varying levels of stiffness from shoulder to crown.
