Select Vehicle or Tire SizeThe Blizzak WS70 is Bridgestone's Studless Ice & 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.
Blizzak WS70 Studless Ice & Snow tires meet the industry's severe snow service requirements and are branded with the three-peak mountain snowflake symbol (3PMSF).
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.

El Blizzak WS70 es un neumático de la categoría de Invierno, sin necesidad de pernos fabricado por Bridgestone y desarrollado para conductores de cupés, sedanes, minivans y utiliautos (crossover) que necesitan tracción en las duras condiciones de invierno donde la nieve, el hielo y aguanieve están presentes. El Blizzak WS70 representa la cuarta generación de los WinterBiter¿ desarrollados para ofrecer tracción y control durante el invierno, y aumentar la confianza del conductor.
El Blizzak WS70 posee un compuesto de caucho doble, la parte superior utiliza sílice mejorado, "Tube Multicell" de Bridgestone y la parte inferior, el compuesto estándar para invierno. El "Tube Multicell" esta compuesto por miles de tubos y celdas distribuidas uniformemente en el compuesto de caucho (parecen queso suizo al ser observadas bajo un microscopio) que absorben y liberan el agua que usualmente se acumula entre el área de contacto del neumático y la superficie con nieve o hielo. A medida que se desgasta el caucho, poros y tubos son expuestos en la superficie de la banda de rodamiento. Este compuesto de caucho flexible, mejora el agarre del neumático en climas fríos, mientras que partículas adjuntas a los tubos que "muerden" el hielo o la nieve compactada, ayudan a mejorar la tracción.
Este compuesto de caucho es moldeado en una banda de rodamiento con diseño direccional, que cuenta con un centro circunferencial flanqueado por bloques intermedios e independientes y bloques con pequeñas ranuras 3-D zigzag sobre sus superficies, que mejoran el rendimiento sobre superficies secas, a la vez de mantener tracción sobre superficies con agua, hielo y nieve. Cuatro canales circunferenciales ayudan a dispersar el agua y aguanieve del área de contacto del neumático con la carretera, ayudando a resistir el deslizamiento sobre agua (hydroplaning) y aumentar la fuerza de frenado sobre carreteras cubiertas con hielo y nieve.
El Blizzak WS70 utiliza la tecnología UNI-T y su estructura interna incluye correas gemelas de acero reforzadas con nailon envuelto en espiral, el cual ofrece mayor durabilidad y mejores características de manejo.
El Blizzak WS70 satisface requisitos de la industria en relación a condiciones de nieve severa, y por eso, posee el símbolo "montaña/copo de nieve" (mountain/snowflake).
Cuando el Blizzak WS70 alcanza el 50% de desgaste, indicadores en la banda de rodamiento, informan al conductor que 10% del resto de la banda utiliza el compuesto "Tube Multicell".
Solamente instale el Blizzak WS70 en grupos de cuatro.
El Blizzak WS70 debe ser instalado en grupos de cuatro, debido a su concepto revolucionario en cuanto a tracción. Al instalar los cuatro neumáticos, puede asegurarse que obtendrá la mejor maniobrabilidad y rendimiento que su vehículo puede ofrecer durante el invierno.

Studless Ice & Snow tires work best when winter is at its worst. But there are plenty of miles driven on dry and wet roads, too. Most of the design elements that aid winter traction reduce clear road handling precision. Increased priority in one area leads to a trade-off in another.

Everyone must be too busy driving.
Drivers living in the northern U.S. have already discovered a set of dedicated winter/snow tires increases their vehicles' wintertime capabilities enough to reduce their driving times, tension and stress. However, if you're among the skeptics who still question if the added traction is worth the expense, watch this video.

Dunlop's new Winter Maxx replaces the Graspic DS-3, which was a nice upgrade in winter traction versus the typical all-season tire, but couldn't match the outright snow and ice performance of the best Studless Ice & Snow tires. How does it compare to category leaders from Bridgestone, Continental and Michelin?
