"A Closer Look at Metzeler motorcycle tyre technology"

 

BIAS tyre THE MOST POPULAR MOTORCYCLE RIMS

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

BIAS-BELTED tyre

The structure of those tyres is realized with a conventional carcass and a belt made of one or more crossed layers. The difference between carcass and belt is given by the different goals that they have to fulfil and consequently the different materials that are used: the belt is mainly made by Nylon and has to reduce the dynamic deformation due to the centrifugal forces, while the carcass has to mainly give the tire its contour.

BELTED TYRE WITH RADIAL CARCASS (90°)

The main difference towards 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, means from one shoulder 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.

0°-STEEL BELTED TYRE WITH RADIAL CARCASS (90°)

Patented technology by Metzeler realizing the structure of both front and rear tyre using a radial carcass and a single layer belt made of steel. Considering the rolling direction of the tyre, the belt is winded circumferentially around the carcass giving an angle close to 0°. The advantages coming from the use of steel are its extremely high rigidity and the possibility to tune the winding spacing giving a differentiated stiffness distribution from shoulder to crown.
