Pirelli
Tyres More and More
Environment-Friendly
A
notable reduction in fuel
consumption (equal to 2.6%)
is found in tyres containing
silica compared to traditional
models (which are mainly
made with carbon black).
For a number of years Pirelli
has mainly been using silica
rather than carbon black
in the manufacture of compounds
used for the tread, resulting
in an 11% reduction in
overall environmental impact.
Pirelli
Group Tyre Sector is constantly
involved, first and foremost,
in the design and development
of new compounds and new
product lines that, thanks
to new materials, innovative
internal structures and
new patterns are capable
of reducing rolling resistance,
bolstering the durability
and especially the safety
and the quality of the
tyre itself. The key target,
in environmental terms,
is optimizing rolling resistance
or, in other words, the
force with which tyre opposes
the advancement of the
vehicle. Resistance offered
by the vehicle’s mechanical
components and air penetration
influences fuel consumption
and, consequently, the
emission of exhaust gases
per unit of distance traveled.
The
rolling resistance
value is naturally
different for the various
types of tyre and depends
on a series of factors
such as the formulation
of the tread compound,
a tyre’s inflation
pressure, the speed
and weight of the vehicle,
the road surface characteristics,
the ambient temperature,
and how a tyre itself
is used. In this context
the ELRR (“Extra
Low Rolling Resistance”)
package has been available
for some years and influences
every component of the
tyre to obtain an improvement
in its general performance
ratings as well as a further
reduction in rolling resistance.
Another
part of total impact is
due to tyre debris, which
refers to rubber particles
worn away as a result of
the friction between the
tread and the road surface:
during its life cycle a
tyre shreds a quantity
of tyre debris, estimated
at around 10-14% of its
original weight. Studies
are currently being carried
out across Europe into
the impact of these particles
on the environment: Pirelli
constantly monitors this
topic through a continuous
exchange of information
and experience with other
tyre manufacturers, through
the BLIC (“Bureau de Liaison
des Industries du Caoutchouc”).
One
final but no less important
aspect associated with
the use of tyres concerns
their noise emissions,
which are studies with
the aid of special software
and testing procedures,
both in the field and through
laboratory testing in appropriately
equipped facilities such
as anechoic chambers.
Pirelli
tyres are marketed in Oman
by their authorized sole
distributor General Trading
Enterprises LLC an OTE
group of company with strong
distribution and service
network spread across Oman.
