Greentrac Quest-X. FEATURES AND BENEFITS: All season traction; Fuel efficient performance; High speed controllability; High driving comfort levels; . OVERVIEW: The Greentrac Quest-X is a high performance, all season tire manufactured for passenger vehicles and SUVs.Excellent all season traction is promoted with this model. The asymmetric tread design, with the optimal sipe and groove placement, works together with the special polymerized styrene-butadiene and silicon compound to offer excellent dry, wet, and light winter traction. Tread elements provide great traction with extra biting edges. Stronger compound elements maintain their rubber flexibility, optimizing the tire's year-round performance. Circumferential grooves prevent hydroplaning, as water and slush are channeled away from the footprint.The stronger compound and consistent traction manage to optimize pressure build-up along the footprint. As a result, the tire helps to ease the pressure off the tire, minimizing its rolling resistance. This is the pressure affecting the tire, which determines the vehicle's needed fuel consumption necessary to keep the tires in motion. Lowering it allows the tire to decrease fuel intake and CO2 emissions, which guarantees a fuel-efficient driving experience.High speed controllability is ensured. This tire was designed for performance. The asymmetric pattern's continuous center ribs optimize its road contact. As a result, it manages to increase the tire's steering responsiveness and driving stability. The heat-resistant compound blend and the even pressure circulation of the footprint minimize the pressure placed on the tread area. This allows the tire to effectively upgrade the tire's high speed durability.The Quest-X helps to promote a quiet drive. The tread design features a five-pitch and multi-steel disc that allows the tire to negate sound waves generated during its performance. In this manner, the tire creates a special sound-canceling frequency, that prevents sound waves from reaching the vehicle's cabin. The driving enjoyment levels are ensured, as road disturbances do not reach the passengers. 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.
