First we start with a precise balance of bead area rigidity and sidewall flexibility. Next comes a cool-running, two-ply rayon casing construction. Then the BAZ Technology™ (spiral-wrapped nylon Banded At Zero degrees to tire rotation) surrounding two high tensile steel reinforcing plies. Your outer layers consist of a wet weather tread compound combined with the aggressive water evacuation of wide circumferential grooves and generously angled grooves, A continuous central rib that transmits steering input and road feedback, tread blocks that are optimally arranged for noise reduction, Massive, stable tread blocks and a gradually rounded shoulder profile, and last, a substantial rim projecting band.
