The Bead Tension Structure and Size-optimized BAZ Technology™ (spiral-wrapped nylon Banded At Zero degrees to tire rotation) helps control the tire’s shape by contributing to resistance of centrifugal forces at high speeds, are what the tires inner layer is made of. The outer layer consists of Advanced Technology tread compounds, Four deep grooves that channel water away from the tire, helping to combat hydroplaning, Advanced technology tread compounds that foster significant adhesion levels in rain and slush, and an Auto-blocking effect of the variable-thickness interlocking ZigZag Sipes.
