The Discoverer A/T3XLT is Cooper's On-Road All-Terrain tire designed for the drivers of pickup trucks, work vehicles and full-size SUVs who need a tire that provides the rugged durability required to keep up with their active lifestyles. Engineered to tackle dirt, gravel, mud and the urban jungle, the Discoverer A/T3XLT combines off-road prowess with agreeable on-road comfort and year-round traction, including in light snow.
Durable-Tread Technology combines a shred-resistant silica compound with the Discoverer A/T3XLT's next-generation all-terrain tread pattern. Cooper's Even Wear Arc Technology optimizes the shape of the footprint for balanced pressure at the contact patch, improving handling and promoting even treadwear. The tread pattern is designed to aid dry traction, while Whisper Grooves between the outboard tread blocks help reduce noise throughout the tire's life. Stone ejector ledges help prevent punctures due to stone drilling, and the Rugged Traction Shoulders feature alternating scoop and cleat lugs and biting edges designed for grip on rock, in thick mud or loose soil. Deep, circumferential channels and wide, lateral notches improve hydroplaning resistance, while multiple zigzag sipes in the independent tread blocks create the biting edges needed for traction in slippery conditions. Snow Groove Technology uses saw-tooth block edges to trap snow in the tread for effective snow-to-snow traction.
The internal construction of the Discoverer A/T3XLT consists of a robust, two-ply polyester casing. A single-ply, nylon reinforcement above two high-strength steel belts further increases durability and handling response, along with providing high-speed stability.
El neumático Discoverer A/T3XLT de Cooper pertenece a la categoría: Dentro/Fuera De Carretera Todoterreno y ha sido diseñado para conductores de picops, vehículos para trabajo y utilitarios deportivos (SUV, por sus siglas en inglés), que necesitan un neumático que proporcione la fortaleza y durabilidad requerida, para mantener las actividades de sus estilos de vida. Construido para lidiar con lodo, grava, tierra polvorienta y la jungla urbana, el Discoverer A/T3XLT, combina habilidad todoterreno con un confort agradable en la carretera y tracción durante todo el año, inclusive en superficies con poca nieve.
La tecnología "Durable-Tread" combina un compuesto de caucho con sílice resistente a roturas, con el patrón todoterreno de la generación siguiente del Discoverer A/T3XLT. La tecnología de Cooper "Even Wear Arc", optimiza la forma de la huella, para obtener una presión balanceada del área de contacto, y así, mejorar la maniobrabilidad y obtener un desgaste parejo. El diseño del patrón en la banda de rodamiento mejora la tracción sobre superficies secas, mientras que, ranuras "Whisper Grooves" entre los bloques externos ayudan a reducir el ruido durante el ciclo de vida del neumático. Rebordes expulsores de piedras previenen pinchazos causados por piedras incrustadas. Hombros fuertes para obtener tracción, "Rugged Traction Shoulders", contienen bloques con espacios y dientes alternados, además cuenta con bordes adherentes diseñados para obtener tracción sobre piedras, lodo y superficies sueltas. Canales profundos circunferenciales y ranuras laterales anchas, mejoran la resistencia al deslizamiento sobre agua (hydroplaning), mientras que, pequeñas ranuras tipo zigzag en los bloques independientes, crean los bordes adherentes necesarios para obtener tracción sobre superficies en condiciones resbalosas. La tecnología "Snow Groove" utiliza bordes serrados en los bloques, para atrapar nieve y hacer más efectiva la tracción nieve con nieve.
La construcción interna del Discoverer A/T3XLT consiste de una estructura robusta de dos capas de poliéster. Una capa de refuerzo de nailon, por encima de dos correas de acero de gran fortaleza aumenta, aún más, la durabilidad y la respuesta al girar el volante, además de proporcionar estabilidad a velocidades elevadas.

i been on wet roads and in snow conditions this tire has performed as advertised...
i spent about a year researching tires and for a all terrain the copper was the best fit for me i mainly use it on the high way and around town with some light off roading i could not be happier. i been on wet roads and in snow conditions this tire has performed as advertised . there is very little road noise the ride is smooth the handling feels tight in control. I'm running a 275/65/20 .on 38 psi getting getting good wear on them.
...Balanced easily, they are great on the highway in the dry and wet...
Wanted to upgrade from stock HTs. These came E rated in 33” and they fit perfectly. Balanced easily, they are great on the highway in the dry and wet. Work shockingly well in the snow and ice. Very strong sidewall but not over stiff. Great on rocks, ok on sand. I bought 5 and do the 5 tire rotation every 5000 miles. After 15k miles they still look new. Tirerack also had a great price on these, unfortunately they were on closeout so I’ll have to pick something else come replacement time.

A little noisy at low speeds but expected with this tread pattern. Excellent traction in wet/snowy conditions. Experience with Tire Rack ordering/delivery is great as usual, satisfied customer!

...Dry and off road is great.
I just checked my mileage on this set of tires that I purchased in February 2020. I can't believe it but I'm at 65,000 on them and still have plenty of life left. These are on my Toyota Tacoma. I have my alignment locked in place w/ tabs (aside from toe) and I do rotate tires (Back to Front, Front Crossed to Back) each oil change and I do 8-9k mile interval changes. These tires continue to impress. If they ever wear out I'm getting them again. Relatively light compared to others in it's category too. Wet performance is good. No problems in snow. Dry and off road is great.

...Wanting something that was highway quite with out the hum. This did the trick...
I overly researched, looking for a good deal. Wanting something that was highway quite with out the hum. This did the trick, but yet look aggressive. I replaced 265 70 17 . SO far so good I lost about 1.5 miles per gallon

...I rotate my tires every other oil change and they are wearing great. They look great as well with the aggressive tread that extends to the shoulders of the sidewall...
Originally wanted Falcon Wild Peak’s but they were a bit more than I wanted to spend and these coopers were on closeout so I figured I’d give them a shot. The gamble paid off. These ties are great both on and off road (we use them off road very frequently). I rotate my tires every other oil change and they are wearing great. They look great as well with the aggressive tread that extends to the shoulders of the sidewall. I’d definitely purchase these again

...With regular rotations, these ties wear very well. no cupping or chopping. Currently have 43k miles on this set and easily have a rotation or 2 left...
All miles are 90% highway and 10% blacktop roads. I typically drive 700miles a week. With regular rotations, these ties wear very well. no cupping or chopping. I have balanced the set once after the 3rd rotation im on the 4th and there isa slight vibration over 80mph. needs another balance. Rotated every 10k. Currently have 43k miles on this set and easily have a rotation or 2 left. not quite to the second wear bar. tire pressure is all set @ 55lbs. Tires are quiet. Hydroplaning got worse as the tires wear, but acceptable if you know the conditions.
