While the P7 name is very familiar to
many sports car drivers, Pirelli's new P7 Ultra High Performance
"summer" tire is entirely different from the legendary tires that
carried the name previously. Pirelli's new P7 was developed for the
drivers of high performance and luxury performance sedans, and is
designed to combine the ability to control horsepower with elegance
and driving comfort.
The new P7 features an asymmetrical tread design that combines stiff
shoulder tread blocks and a continuous solid rib on the outer
portion of its pattern to resist lateral forces while the inner ribs
combine circumferential and curved transverse grooves for rapid
water expulsion from the contact patch to enhance wet traction and
reduce the possibility of hydroplaning. The tire features a wide
footprint with a uniform distribution of load pressures to promote
even tire wear and reduce rolling resistance.
Pirelli's innovative STEP project (Safety from Technically
Engineered Profile) has developed the new P7 profile to achieve a
reduced deformation in the critical areas for greater reliability
and structural integrity. Pirelli's patented ELRR (Extra Low Rolling
Resistance) system results in the belting and carcass materials
being designed and constructed to improve flexibility and increase
rolling smoothness, while overall weight is reduced and integrity is
optimized.
