MOTORCYCLE TYRES KNOWLEDGE

While motorcycle tires have existed for more than 100 years, their appearance has changed dramatically.
Modern motorcycles have little in common with early motorcycles that were modeled after bicycles.
One consistent part is the tyre, which has been an integral piece of the motorcycle since its inception.
Modern radial tyres made by PIRELLI are high-tech and have progressed since their introducion on motorcycles of 100 years ago.
Below you will find the various constructions that PIRELLI uses today.

The tyre is the only part of the motorcycle that makes contact with the road.
That is why correct use and maintenance of your motorcycle’s tyres, as well as knowledge of the tyre’s characteristics,
increases the lifespan of the tyre, saves money and promotes safety. Always remember to ride drive safely and respect the environment.

RADIAL CROSS BELTED
CONSTRUCTION

The main difference from the bias-belted construction is the structure of the carcass in this case is radial.
This means that its cords are wrapped radially around the tyre, from one bead to the other,
giving big advantages in terms of cornering stability, reduced weight and high-speed performance.

BIAS BELTED
CONSTRUCTION

The structure consists of a conventional carcass and a belt made of two or more crossed layers.
The difference between the carcass and the belt is determined by the different goals they are designed
to fulfill and consequently different materials are used in the construction. The belt is made mainly
from Aramide and its function is to reduce the dynamic deformation caused by centrifugal forces,
while the carcass provides the tyre with its stiffness and load carrying capacity.

CROSS PLY
CONSTRUCTION

Also indicated as conventional or x-ply tyre. Depending on the different speed and load specifications,
the tyre carcass is structured using two or more overlapping layers.
Each layer is made of rubber coated textile cords and the overlap angle
is designed in order for the tyre to conform with the required dynamic characteristics.
