The Blizzak WS70
is Bridgestone's Studless Ice and Snow winter tire developed
for the drivers of coupes, sedans, minivans and crossover
vehicles looking for traction on winter's slushy,
snow-covered and icy roads. The Blizzak WS70 represents the
fourth generation of Bridgestone WinterBiter tires designed
to deliver wintertime traction and control that inspires
driver confidence.
The Blizzak WS70 features a dual-compound tread with
Bridgestone's NanoPro-Tech silica-enhanced Tube Multicell
compound layered on top of a standard winter compound. The
Tube Multicell compound features thousands of microscopic
tubes and cells uniformly distributed throughout the
compound (which makes the rubber look like Swiss cheese when
examined through a microscope) that wick away the water that
often forms between the tire's contact patch and the surface
of snow-packed and icy roads. New pores and tubes are
constantly exposed around the tread as the tire wears. This
flexible rubber compound improves the tire's grip in cold
conditions while the bite particles attached to the tubes
scratch at packed snow and icy surfaces for traction.
This unique tread compound is molded into a directional
tread design consisting of a circumferential center rib
flanked by independent intermediate and shoulder blocks that
feature 3-D zigzag sipes to enhance dry road performance
while maintaining snow, ice and wet traction. Four main
circumferential grooves help disperse water and slush away
from the tire's contact patch to increase hydroplaning
resistance and enhance braking force on snow-covered and icy
roads.
Featuring Bridgestone's UNI-T Technology, the Blizzak WS70's
internal structure includes twin steel belts reinforced by
spirally wound nylon to provide the desired high-speed
durability and ride characteristics.
When the Blizzak WS70 is 50 percent worn, a tread depth
indicator molded into the tread design lets the driver know
that only 10 percent of the remaining tread is the Tube
Multicell compound.
Install Bridgestone Blizzak WS70 tires in sets of four only.
Due to the traction capabilities of Blizzak WS70 tires,
Bridgestone recommends using them only in sets of four to
provide the best handling characteristics and tire
performance. |
