- Lamella crystals, called Fraipontite, help "vacuum" away moisture from under the footprint allowing better direct contact between the tread compound and the road surface. - Silica in the tread compound helps rubber retain it's softness in low temperature conditions and resists hardening with age. - Improved Microbit Technology with the larger walnut shell particle, increases traction and braking on compacted snow and ice. - Increased sipe density further improves water evacuation resulting in improved levels of ice traction.
