The Discoverer Road+Trail AT is Cooper's On-Road All-Terrain tire, built for the drivers of pickups, work vehicles, and SUVs who need a tire with the rugged durability to keep up with their active lifestyles. Engineered to tackle dirt, gravel, mud and the urban jungle, the Discoverer Road+Trail AT combines off-road prowess with agreeable on-road comfort and year-round traction. It even handles light snow well enough that it meets the tire industry's severe snow service rating requirements and earns the three-peak mountain snowflake (3PMSF) symbol.
A durable compound resistant to cutting, cracking and tearing joins with the Discoverer Road+Trail AT's next-generation all-terrain tread pattern. This design features rugged, interlocking tread blocks off-roaders expect working alongside Cooper's Road Glide Technology to provide a smooth, quiet experience on the pavement. The alternating scoop and cleat lugs in the shoulder, sporting a thick, angled design further down the sidewall, were created to find grip on rock, in thick mud or loose soil. Deep, circumferential grooves and wide, lateral notches improve resistant to hydroplaning. The interlocking center tread lugs provide stability on the road and snow, while zigzag sipes in the shoulders create the biting edges needed for traction in slippery conditions.
The internal construction of the Discoverer Road+Trail AT 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.
Note: While non-winter tires featuring the three-peak mountain snowflake (3PMSF) symbol may provide additional longitudinal snow traction beyond what all-season (M+S) tires not bearing the symbol can deliver, they do not match the capability of a true winter tire in all adverse weather conditions.
El neumático Discoverer Road+Trail AT de Cooper pertenece a la categoría: Dentro De Carretera Todoterreno y fue fabricado para conductores de picops, vehículos de trabajo duros y vehículos utilitarios deportivos (SUV, por sus siglas en inglés), que necesitan un neumático durable y fuerte, que pueda mantener su estilo de vida activo. Diseñado para enfrentar la tierra, grava, lodo y la jungla urbana, el Discoverer Road+Trail AT, combina destreza todoterreno con una comodidad agradable en carreteras y tracción durante todas las estaciones del año. Incluso, maneja nieve ligera al punto de satisfacer los requisitos de la industria, en relación a condiciones de nieve severa, por esta razón, cuenta con el símbolo “tres picos montaña/copo de nieve”, 3PMSF (three-peak mountain snowflake symbol, 3PMSF).
El compuesto de caucho durable resistente a cortaduras, rajaduras y desgarros del Discoverer Road+Trail AT, trabaja conjuntamente con un patrón de la huella de próxima generación. Este diseño posee bloques fuertes todoterreno entrelazados, que trabajan junto con la tecnología "Road Glide" de Cooper para proporcionar un andar parejo y tranquilo sobre pavimento. El diseño de "cucharas alternadas" en los hombros, con tacos gruesos y angulados en la parte más baja de los hombros, fueron creados para proporcionar tracción sobre piedras, lodo espeso o tierra suelta. Canales circunferenciales profundos y ranuras laterales anchas mejoran la resistencia al deslizamiento sobre agua (hydroplaning). Los tacos o bloques centrales entrelazados de la huella proporcionan estabilidad en la carretera y superficies con nieve, mientras que pequeñas ranuras tipo zigzag en los bloques de los hombros, proporcionan los bordes adherentes necesarios para ofrecer tracción sobre superficies resbalosas.
La construcción interna del Discoverer Road+Trail AT consiste de una estructura robusta de dos capas de poliéster. Una capa de refuerzo de nailon por encima de dos capas de acero de gran fortaleza, aumentan aún más, la durabilidad y respuesta, a la vez de proporcionar estabilidad a velocidades altas.
Nota: Mientras que los neumáticos que no son para uso exclusivo de invierno, pero cuentan con el símbolo tres picos montaña/copo de nieve, 3PMSF (three-peak mountain snowflake, 3PMSF) podrían proporcionan mayor tracción longitudinal en nieve, que la ofrecida por neumáticos para toda estación (M+S) sin el símbolo 3PMSF; ninguno iguala la capacidad de un neumático para uso exclusivo en el invierno, en climas con condiciones adversas.

...Additionally my area has experience very heavy rains this Spring and I have had no hydroplaning at all and have yet to brake the tires loose in any condition. The grip is very impressive.
I installed the Cooper Discoverer Road and Trail AT on my Jeep just before the snow started to fall. Very glad I did. These tires did exceptionally well in the winter elements. I had no trouble navigating thru 3-4 inches of snow confidently and in control. Additionally my area has experience very heavy rains this Spring and I have had no hydroplaning at all and have yet to brake the tires loose in any condition. The grip is very impressive. I have also taken them on a few 100+ mile road trips and the ride is just as good as a highway tire, very comfortable and smooth. Very happy with them.

...hooked up fine on a snowy and icy off road driveway without 4 wheel drive. Usually have to use 4 wheel drive to get out...
Tires are some of the lightest weight tires in this class. Super quiet on road, while being solid to hook up off road. Been amazed at how quiet and mannerly these are compared to the Falken AT3s these replaced. Haven’t tried in deep snow yet but hooked up fine on a snowy and icy off road driveway without 4 wheel drive. Usually have to use 4 wheel drive to get out. Very impressed so far.

...The Cooper has been awseome for the light snow we've been getting in Michigan. I'd have needed 4x4 with the Hankook AT but the Cooper had amazing grip in 4x2. I've towed my cargo trailer flawlessly...
No wonder this is the #1 rated tire in the catagory. Extremely satisfied with its performance and improvement over the Hankook Dynapro AT2 that comes stock on F150. I had over 200,00 miles on sets of Hankook Dynapro AT2 and was consistenly disappointed. The Cooper has been awseome for the light snow we've been getting in Michigan. I'd have needed 4x4 with the Hankook AT but the Cooper had amazing grip in 4x2. I've towed my cargo trailer filled with sleds flawlessly. I've driven on tight and steep off-road trails covered in deep snow. The sand road leading to my cabin used to need 4x4 but the Cooper AT easily manages. If my MPGs dropped, it hasn't been noticable yet...the slightly larger diameter probably offsets the extra 16 lbs of rotating weight. My wife knows nothing about automotive and instanly said the truck felt so much safer and in control. I'd buy these again tomorrow.

...The Cooper Discoverer is great in heavy rain and provides excellent dry traction... Tires feel very secure and more connected to the road than my old Hankook's. They are responsive to steering inputs and feel very smooth on asphalt and concrete highways.
Bought my truck new with Hankook Dynapro Extreme AT2 tires. Changed to the Cooper Discoverer Road/Trail AT to get better tread wear and more traction in off road and inclement weather conditions. The Cooper Discoverer is great in heavy rain and provides excellent dry traction.
The tire ride is a little less refined than prior tires. However, the difference is very slight. Very low noise at highway speed and a slight whistling sound at low speeds ( -30 mph). Tires feel very secure and more connected to the road than my old Hankook's. They are responsive to steering inputs and feel very smooth on asphalt and concrete highways. They absorb the expansion joints between concrete sections on interstate highways well. Very smooth and quiet ride.
The Discoverer has excellent wet traction and resist hydroplaning even at highway speeds ( 65 - 75 mph ) in heavy rain.

Just had these tires installed not long ago and wow what a difference. Let me just say, these are probably the best wet traction tires I've ever experienced. TireRack has a great review on these tires along with several other AT and highway AT tires. I highly encourage anyone looking to watch the video review and read through the text review. The review heavily influenced my decision to ultimately purchase these specific tires and I'm glad I did. Would definitely buy again.

...They are quiet, comfortable, and as far as I can tell, they perform well in most all conditions...
I bought these Cooper Discoverer Road + Trail ATs in size 275/60/20 for my 2017 Tundra. They replaced Goodyear Workhorse HTs that were a size smaller at 275/55/20. The Goodyear tires were fine, but I wanted something better and more suitable for off-road trails and snow. I also wanted to size up a bit from factory spec because my truck has a 2" leveling kit and I felt I needed to fill up that wheel well a bit more for a better appearance.
By sizing up I added about 4 lbs per tire, which after doing some calculations to account for the size difference, appears to have had a minimal impact on gas mileage. Maybe lost a half mile per gallon of gas. I know some people have stated that they have lost 1 or 2 mpg by switching to these Coopers. I have to wonder if they switched from a standard load tire to a higher load rated tire. Many of the Cooper Discoverer Road + Trail AT sizes come in XL load ratings, which adds significant weight to the tires. In my particular size, I was able to stay with the standard load (SL) rated tire which is what I wanted. I don't tow anything and don't haul very heavy loads.
I've only put 1,250 miles on these tires, but I've driven them in most conditions that I will be encountering. They seem to perform great on wet or dry pavement. I have taken them out on some off-road dirt trails which included some steep and rocky inclines and they performed really well there too. Lastly, I have taken them up to the mountains with about 6" of snow. The roads were already plowed, but my driveway was covered with hard packed icy snow. Driveway is at approximately 15 degree incline. I did need 4 wheel drive to get up the driveway, but I was impressed with the controlled feeling going up and down the driveway, with minimal sliding around.
In summary, I am very happy with these tires. They are good looking, quiet, comfortable, and as far as I can tell, they perform well in most all conditions. Hopefully they wear well. Time will tell on that.

This is my 2nd set of Road & Trails. I loved my first set so much, when I decided to get new wheels to wrap them in the same ones. My stock wheels with these tires have around 15k miles on them and hardly show signs of wear.
