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.

Ratings Charts & Reviews Cooper Discoverer AT3 XLT
Drivers consistently rate the Michelin Defender T+H as an outstanding all-season touring tire, with exceptional scores (9-10) in treadwear, dry traction, and hydroplaning resistance. Comfort receives high praise for smooth ride quality and low noise, aligning with touring expectations. Winter traction is generally strong in snow and slush (7-10 range), though a few users report reduced confidence on ice. Wet performance shines with near-perfect ratings for grip and stability. Longevity stands out as a key strength, with many users noting the tread holds up well over extended mileage. While winter capabilities are solid for an all-season tire, occasional lower ice scores suggest cautious driving in severe conditions.

...A little quieter, better wet traction, MUCH better fuel economy than the goodyear eagle sports...
I put 15 inch wheels on my 2024 Civic Sport to replace the overkill 18s that came from the factory. Got these 205/65r15s from Costco. These are an improvement in every way that matters to me. A little quieter, better wet traction, MUCH better fuel economy than the goodyear eagle sports. With 11k mostly highway miles they have worn down by about 1.5 32nds from 10.5 to 9. They are good tires and I'm happy with them but they are quite pricey and I will be experimenting with less expensive tires next time.

...Very good wet weather traction here on the Gulf Coast. As the tire wears down it even gets better.
These are my second set of this tire on this vehicle. First set got over 100,000 miles. Very good wet weather traction here on the Gulf Coast. As the tire wears down it even gets better.

...Excellent traction in dry, wet and snow, even deep snow in a rather low vehicle. I have only gotten stuck with these tires because the snow was too deep that is beached the vehicle, not a tire issue...
I bought these after getting multiple recommendations for Michelin Tires as long lasting tires. What I didn't expect is that the Defenders would serve as the best all around tire there is. Long life, these tires after 3 years and 25000 miles look the same as the day they were put on. Excellent traction in dry, wet and snow, even deep snow in a rather low vehicle. I have only gotten stuck with these tires because the snow was too deep that is beached the vehicle, not a tire issue. They are quiet and the car feels smooth going down the road. Only gripes are I think I lost 1 mpg and they are a bit pricey, but for how long they last, they do make up for it in not paying to new tire installation often. All around, I cannot recommend the Defender series tires enough for on-road use, off-road might be a different story, but no other tire does everything so well for a somewhat reasonable price.

...The dry traction is nothing short of unbelievable. And when they finally do get pushed into sliding traction, they only lose a small amount of adhesion to the road, making vehicle control as easy as when they're in non-sliding mode...
In long sweeping decreasing radius curves I can get enough speed up to push the car into a four wheel slide, but these tires are stuck to the road so firmly that it takes this kind of 60 mph speed in a short radius curve to finally get them to slide. The dry traction is nothing short of unbelievable. And when they finally do get pushed into sliding traction, they only lose a small amount of adhesion to the road, making vehicle control as easy as when they're in non-sliding mode. I routinely push the car to autocrossing cornering loads, because it's just plain exhilarating to whip the car around like driving on a autocrossing course. The tires rarely get pushed hard enough to slide, and it's easy to maintain control. The traction of these tires make me a far better driver than I actually am. Wet traction is just as impressive, they grip to a point that I've never experience before with any other tire I've driven on in 50 years of driving. Nothing but the highest praise for these tires. I wonder if so called performance tires could do any better. My thanks to Michelin for their excellence in tire design, construction, and accurate manufacturing. Well worth the price, I'm putting them on all my vehicles as they need tire replacements.

Great comfortablequiet easy driving tire...
Great comfortable quiet easy driving tire. Had them for 6 and a half years and we got 77,000 miles out of them. There are a lot of nice tires out there and this is one of the best. They are very worn down and have some dry rot but they survived Florida for over 6 years and 77000 miles. Thank you Michelin !

...They are very comfortable and quiet on the highway, they get great gas milage...
These came on my car from the dealer. At first I was like nice Michelins. I have now driven the car for a year with these tires and boy are they bad in the wet and snow traction is worse then the UHP summer tires on my BMW e30. They are very comfortable and quiet on the highway, they get great gas milage. They are vague at best on the limit. Driving backroads, which i do often, these tires do little to communicate what is going on. Having grown up in western NY I'm accustom to driving in the snow and ice, the little we get in Eastern Maryland these tires could not cope with. They were down right dangerous with any amount of wet, add cold to that and I'm shocked they can label these tires all season. now having to replace one as it is dry rot and chunking off the side wall. Thankfully it is on the dealers dime because they are far to expensive for what they deliver. In the future I will not be going with these tires in fact these have soured me on Michelins altogether.
These tires are quiet and handle great... It pays to spend the little extra for the comfort, safety and longevity.
These tires are quiet and handle great. I've had many sets of Michelins and they never disappoint. I've tried some other brands to save a few bucks, and I've always been disappointed. It pays to spend the little extra for the comfort, safety and longevity.

...The treadwear, warranty and reliability are superb...
These are my go-to tires. This is the 4th set I have owned. The treadwear, warranty and reliability are superb. This set of Defenders replaced OEM Bridgestone Ecopias, that were worse than terrible. The Michelins provided a much better ride, along with big improvement on wet, snow and ice.
I will buy Defenders again and highly recommend them.
