The RS-W 5.0 is a value-driven, studless tire engineered to grip winter roads in all types of driving conditions. Whether roads are snow-covered, icy, wet or slush the RS-W 5.0 uses design and compound innovations that handles winter's worst weather.
The combination of 3-D and multi-pitch sipes create over 2,500 biting edges throughout the life of the tire. These biting edges increase ice and wet grip for improved winter handling.
All-season tires can begin to lose performance as temperatures get colder. Specialized polymers ensure the tread compound of the Starfire RS-W 5.0 remains flexible enough to grip and handle extreme winter driving conditions. Unlike all-season tires the RS-W 5.0 is able to stay flexible and maintain grip well below -30C.
The three circumferential grooves allow the Starfire RS-W 5.0 to pack snow into the grooves to create snow-on-snow traction, much like two snowballs being stuck together. Winter driving can see a variety of conditions so these grooves also serve to evacuate slush and water.
The integration of tie-bars in the shoulder ribs stabilizes the outer tread elements giving better handling response while still evacuating slush and rain.
By adding chamfers, or bevels to the edges of some of the tread elements this reduces noise and tread “squirm” leading to better handling and tread wear.
