The Discoverer S/T Maxx is Cooper's Commercial All-Terrain light truck tire developed for the drivers of pickup trucks, SUVs, full-size crossovers and vans looking for a tough tire that provides the traction needed to navigate the loose terrain of job sites, gravel roads and off-road use. In addition to off-road capabilities, the Discoverer S/T Maxx is designed to deliver confident paved-road performance in dry, wet and wintry conditions, including snow.
The Discoverer S/T Maxx utilizes a cut- and chip-resistance compound molded into a symmetric, hybrid four-five rib design for low pattern noise and to promote even wear. The open pattern and multiple block edges provide the clawing traction necessary when negotiating soft, uneven soil, rocks or gravel. Stone ejector ribs and the non-parallel groove walls help resist rock retention, improving longevity by preventing stone drills that may potentially damage a tire. In-block sipes create the biting edges needed for traction in wet conditions, and the high-void pattern provides ample drainage away from the footprint for hydroplaning resistance. Discoverer S/T Maxx tires are molded to accept optional #15 metal studs to enhance traction on packed snow and ice.
Cooper's Armor Tek3 construction utilizes two 90 degree radial body plies, in addition to a third body ply with an eight degree bias to help reduce gaps between sidewall body cord. Two high-strength steel belts support the tread, while the nylon reinforcement above the steel belts provide high speed durability.
El neumático Discoverer S/T Maxx de Cooper pertenece a la categoría: Dentro/Fuera De Carretera Tracción Comercial para camiones ligeros. Fue desarrollado para conductores de picops, utilitarios deportivos (SUV, por sus siglas en inglés), utiliautos (crossovers) y camionetas; que buscan un neumático fuerte que proporcione la tracción necesaria para conducir sobre superficies sueltas en algunos sitios de trabajo, carreteras de grava o cualquier uso todoterreno. Además de la capacidad todoterreno ofrecidas por el Discoverer S/T Maxx, su diseño proporciona confianza sobre calles pavimentadas en condiciones secas, mojadas o invernales, incluyendo superficies con nieve.
El compuesto de caucho del Discoverer S/T Maxx es resistente a cortes y astillas, y es moldeado en una banda de rodamiento simétrica con cuatro-cinco segmentos híbridos, diseñados con un patrón que produce poco ruido y promueve un desgaste parejo. El patrón abierto de la banda de rodamiento y múltiples bordes en los bloques, proporcionan la tracción necesaria sobre superficies suaves, disparejas, con piedras o grava. Segmentos que expulsan piedras y paredes con ranura no paralelas ayudan a resistir la retención de piedras, mejorando la longevidad al prevenir perforaciones causadas por piedras, que podrían dañar el neumático. Pequeñas ranuras sobre la superficie de los bloques, proporcionan los bordes adherentes necesarios para obtener tracción en condiciones mojadas, además, el patrón con bastante espacio permite un drenaje fluido desde el área de contacto con la carretera, para así, mejorar la resistencia al deslizamiento sobre agua (hydroplaning). Los neumáticos Discoverer S/T Maxx pueden aceptar pernos opcionales para mejorar aún más la tracción sobre superficies con hielo y nieve compactada.
La construcción "Armor Tek³" de Cooper utiliza dos capas radiales de 90 grados, además de una tercera capa con un sesgo de 8 grados, ayudan a reducir el espacio entre la estructura de cordón del flanco. Dos correas resistentes a tensiones fuertes soportan la huella, mientras que, el refuerzo de nailon por debajo de las correas de acero proporciona mayor durabilidad debido a su uso a velocidades elevadas.

...Since I also commute to Reno on a regular basis the weather can rapidly change and these tires work magnificently, and have never hydroplaned on me...
Best snow tire ever! I drive all winter in the Tahoe region where we can get 350-700 inches of snow per year. These tires are so amazing I rarely even need to use 4 wheel drive. Since I also commute to Reno on a regular basis the weather can rapidly change and these tires work magnificently, and have never hydroplaned on me. For use in two of my pick up trucks, these tires have been winter saviors.

...Since I've put these tires on my Tundra (no weight in the bed) I have complete confidence to take on any snow conditions that are thrown at me. In 4 wheel drive there isn't much that these tires cannot handle.
I purchased these snow tires specifically for the snow bands that impact Central, NY. We can get snow in the feet and tires are essential. Since I've put these tires on my Tundra (no weight in the bed) I have complete confidence to take on any snow conditions that are thrown at me. In 4 wheel drive there isn't much that these tires cannot handle.

This is our second winter with these tires. The tread is wearing well. We did not have much snow last year. We got stuck in a snow storm this year about 4 inches of snow, The roads were covered in packed down snow in parts and slushy in others. My rear wheel drive Econoline had no issues handled the white stuff great only spun once when stopped at a red light. Might have been me being over confident. Great snow tires.

Got these for a Montana winter. Did pretty well in most winder snow/ice conditions. Mine were not studded. Kept them on through the summer out of laziness and tread wear has been stellar!

...Treadwear is excellent for the soft rubber it is. Can't see any wear after about 3,000 miles.
These tires with studs have been through two winters in Eastern Washington, and do just what I bought them for. They grab and hold on snowy and wet surfaces, Not noisy for studded winter tires.
