Nokian Tyres plc is updating its all-weather product line with the Nokian WR G4, a tire that promises reliable winter grip in snow and slush and year-round performance in heavy rain or hot, dry pavement.
The tire is available in sizes for 14-inch to 19-inch wheels, and speed ratings from H to V.
The WR G4 is designed to steer precisely, like an all-season tire on dry or wet roads. In the winter, the tire provides predictable grip and the 3D locking sipes improve lateral stiffness.
“The sturdy and stiff outer shoulder of the tire ensures stable and controlled handling at higher speeds,” says Olli Seppälä, product development manager for Nokian. “You can always rely on it to bring you home safely.
“The rib also has hinges at the ends of the blocks, which reduces block movement. This lowers rolling resistance, which in turn improves fuel efficiency and wear resistance.”
The inner shoulder’s fan-like rib pattern with functional tread blocks and blade grooves move rain, snow and slush away from the contact surface. The sipes, staggered at different angles, provide longitudinal grip and acceleration grip on snow and the wide longitudinal grooves offer lateral grip.
The tire comes equipped with new Coanda Technology which combats the risk off hydroplaning. The curved, ramp-like design of the tread blocks on the inner and outer shoulder guides and accelerates the flow of water from the longitudinal grooves into the transverse grooves. Nokian says these hydroplaning prevention properties are retained even as the tire wears.
The Nokian WR G4 features silent sidewall technology, which includes a tailored special rubber compound between the sidewall and tread which actively filters the sound and vibration originating from the driving surface, preventing the passage of sound waves through the sidewall into the rim and further into the passenger compartment. A special clinch rubber compound was also developed for the Nokian WR G4’s bead area near the tire which minimizes interior noise in the vehicle by damping the vibrations from the tire body.
