Green Max Optimum HP. FEATURES AND BENEFITS: All weather traction; Longer lasting tread life; High speed controllability; High driving comfort levels; . OVERVIEW: The Green Max Optimum HP is a performance, all season tire manufactured for passenger vehicles and SUVs. This model also offers touring sizes as well.The tire upgrades the all weather traction. The all season compound and the ideal tread pattern upgrade the dry, wet and winter weather grip on the road surface. The year round compound keeps the rubber flexibility throughout the drive, by utilizing stronger compound elements. The tread design, with the siping placement, firmly grips on the road surface with extra biting edges. The circumferential grooves prevent hydroplaning by dispersing water and slush from below the footprint, which further improves the wet and winter weather driving safety levels.The stronger compound and the flat footprint work together to boost the tread life length. The tread pattern's surface contact enhances the pressure distribution along the tread area. The equally spread out forces of acceleration, cornering and braking resist irregular wear formations. The compound resists premature wear formations in order to extend the usability. This combination enables the tire to significantly increase the tire's service life.The tread's ribbed pattern manages to maintain the surface contact throughout the drive. The better road contact upgrades the steering responsiveness and the driving stability. This enables the tire to improve the steering response time and accuracy to the driver's commands, while the structure is stabilized against the driving pressure. The shoulder block placement improves the cornering ability with extra biting edges. The durable compound is heat resistant, while the tread optimizes the pressure distribution. This combination eases the high speed pressure off the tire, which ensures its safer high speed performing ability.The Optimum HP provides a comfortable drive. The longitudinal stability of the structure and the ribbed tread design maintains the close surface contact. As a result, the tire is able to absorb the shock of driving during the drive, which significantly lowers the road vibrations felt in the vehicle's cabin. This prevents road vibrations from ruining the passengers' driving enjoyment, increasing the driving comfort levels while the tires are in motion. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
