On the outside, the SP Sport 9000 tire features a high silica content tread compound molded into a design that features substantial open grooves (44% groove - 56% rubber) in the center of the design to minimize hydroplaning, and directional high contact shoulder grooves (85% rubber - 15% groove) to enhance steering response and dry road cornering. On the inside, Jointless Bands (JLB) of nylon provide high speed capability while helping improve ride comfort and handling. The SP Sport 9000 construction provides light weight structural integrity, splice free reinforcement uniformity, and an even distribution of footprint pressure.
