• 360 degree variable sipe technology with distinctive full depth and interlocking sipes provides biting edges for improved traction in wet and light snowy conditions
• Interlocking sipes produce supplementary biting edges within the contact patch that ensure superb traction on wet and light snow covered roads

The tire features large reinforced outboard shoulder blocks that help deliver lateral grip, while Dynamic Response Technology evens out forces exerted on the contact patch during hard cornering, improving handling characteristics and tread wear. Wide circumferential channels combine with large rain grooves to evacuate heavy water from the contact patch, helping increase hydroplaning resistance, further enhanced by the Extreme Silica Compound.
