The Grandtrek AT20 is Dunlop's Highway All-Season light truck tire that was developed for the drivers of pickups and sport utility vehicles. The Grandtrek AT20 was designed to deliver low noise, a comfortable ride, and year-round traction, even in light snow.
The numerous Grandtrek AT20 sizes developed for the aftermarket are branded with UTQG Ratings of 500 A B and have been designed to provide a balance of traits appropriate for today's lavish pickups and luxury sport utility vehicles, while the few Original Equipment Grandtrek AT20 tires developed several years ago are branded with UTQG Ratings of 300 B B and appear to place emphasis on low rolling resistance to increase the vehicle's fuel economy above poor weather traction and treadwear.
On the outside, the aftermarket tires feature Dunlop's advanced all-season compound molded into a tread design that combines independent intermediate and shoulder blocks with a continuous center rib to enhance dry traction and treadwear. Then crosscut sipes, wide circumferential grooves and deep lateral grooves provide the biting edges needed to enhance poor weather traction. On the inside, twin steel belts stabilize the tread while a Dimensionally Stable Polyester cord body and bead design promote ride comfort, handling and treadwear.
El neumático Grandtrek AT20 de Dunlop pertenece al segmento Autopista Para Toda Estación y fue desarrollado para conductores de picops y utilitarios deportivos. El Grandtrek AT20 fue diseñado para ofrecer un andar confortable, ser silencioso y ofrecer tracción durante todo el año, incluyendo superficies con poca nieve.
El Grandtrek AT20 ha sido fabricado en gran cantidad de tamaños y poseen una clasificación de 500, A, B del UTQC (Departamento de Transporte de Estados Unidos); su diseño busca encontrar un balance de las características apropiadas para la actual gama de picops y utilitarios deportivos de lujo. También existen algunos Grandtrek AT20 “Equipo Original” desarrollados hace algunos años que poseen la clasificación UTQC de 300, B, B. Al ser diseñadas, se hizo énfasis en ofrecer baja resistencia al rodamiento para aumentar la eficiencia del combustible.
La construcción externa del Grandtrek AT20 regular, posee la avanzada mezcla de caucho Dunlop para Toda Estación y la moldea en un diseño que combina bloques independientes intermedios y bloques en los hombros, con un segmento central continuo que aumenta la tracción en suelo seco y mejora el desgaste. Pequeñas ranuras sobre la superficie de los bloques, canales circunferenciales anchos y ranuras laterales profundas, se encargan de ofrecer tracción en condiciones climatológicas difíciles.
Internamente, el Grandtrek AT20, posee correas gemelas de acero que estabilizan la banda de rodamiento. Un cordón de poliéster “Dimensional y Estable” en la carcasa, y un alambre de aro o talón aseguran un andar confortable, buena maniobrabilidad y características sobresalientes de desgaste.
