New high-silica, next-gen polymer/resin compound plus revised tread (angled center grooves, shoulder and horizontal sipes, optimized pressure distribution) boosts winter performance vs. wintrac pro: +4% snow braking, +5% snow traction, up to +20% snow handling; wet grip remains best-in-class.

Rolling resistance reduced by up to 7% vs. wintrac pro (often a label-class improvement), increasing fuel efficiency and ev driving range.

Stronger wear resistance and durability from advanced polymer/filler blend, retaining the line’s segment-leading mileage and lowering whole-life cost.

Greener construction: renewable/recycled inputs up to 26.5% (from 20.4%) and cradle-to-gate co2 cut by 4% vs. wintrac pro.

Broader fitment and capability: 120+ sizes for 17- to 22-inch rims, mostly y speed rated up to 300 km/h, many xl load indices, all with 3pmsf certification.
