S FIT AS tires mold an ultra high performance all-season compound into an asymmetric tread design. Tie bars connect the shoulder blocks to improve dry road handling and promote even wear while Multi-Tread Radius Technology optimizes the tire's contact patch, further reducing the likelihood of irregular wear patterns. Four wide circumferential grooves and streamlined intermediate notches designed with 3D hydroplaning simulation technology help evacuate water while multiple sipes increase the number of biting edges to generate traction in light snow. The Laufenn S FIT AS tire's internal structure includes two wide, steel belts reinforced with a jointless nylon full cover to improve high-speed handling and durability. A single strand bead wire improves bead uniformity to optimize ride quality, and the high-hardness bead filler is designed to improve handling and steering response
