TREAD PATTERN COMPOUND<br />
It consists in the usage of two or more tread<br />
compounds in different areas of the tyre, i.e.<br />
center and shoulders.<br />

Speed<br />
The tyre preserves its<br />
shape also at high speed<br />
From a technical point of view, the aim is to<br />
create tailored performance outputs in<br />
different areas of the tyre.<br />
A harder compound<br />
in the center<br />
provides mileage<br />
and stability.<br />
A soft compound on<br />
the shoulders will<br />
increase grip in lean.<br />
