A double TWI indicator for the winter Marix retreads
December 13, 2011
An important contribution to tradition and safety for the cold season
"The
retreaded winter tyres Ecogrip and Ecotrac of the Marix Ecology series have a
double TWI (tread wear indicator)" says Brenno Benaglia, Sales Director of
the Commercial & Earthmover Tyres division of Marangoni SpA, as - in view
of the upcoming winter season - he reminded us of some of the characteristics
of the car retreads that are manufactured in the establishment of Rovereto.
"We
have in fact", continues Benaglia, "planned a second TWI indicator
for these products.
We added
the second indicator to help us identify when a residual sculpture of less than
4 mm is reached, which could compromise the performance and safety of the vehicle
under winter conditions and snow, in addition to the 1.6 mm indicator that is
required by law".
The
retreaded Marix Ecology winter tyres are suitable for use even when the
temperature goes under 5-7° C, regardless of the road conditions: dry, wet or
covered with snow.
The development of the specific silica-based compounds with
advanced characteristics that are able to ensure a better adherence in case of
low temperatures, even way below zero, is the basis of this Marix Ecology tyre
evolution.
The Marix
Ecology tyres of the Ecogrip and Ecotrac series can be used up to the legal 1.6
mm limit when the retreads are worn beyond 4 mm, just like normal non winter
tyres.
