The Ridge Grappler is Nitto's Rugged All-Terrain tire developed for drivers of SUVs, Jeeps, and pickup trucks seeking a stylish, capable, and durable off-road tire that can be reasonably driven in towns and highways in-between their adventures.
The Ridge Grappler's durable compound is molded into a symmetric tread pattern featuring robust reinforced tread blocks with tapered edges which optimize surface contact for competent dry grip. Variable pitch tread blocks of slightly different sizes reduce road noise for enhanced on-road comfort. Step block edges and staggered shoulder lugs combine for advantageous grip characteristics across many all-terrain environments. The Lateral zig-zag patterned Z grooves promote efficient water evacuation to the shoulder notches, while sipes in the tread blocks assist hydroplaning resistance and wet traction on paved surfaces. A high void ratio and multitudinous biting edges deliver confident traction in light snow.
Internal Construction of the Ridge Grappler includes a two-ply reinforced polyester casing for durability and ride comfort. Two high-tensile steel belts offer a sturdy foundation for even load distribution across the footprint. Two nylon reinforcement plies further stabilize the tread for high-speed handling and durability.
As with all Grappler tires, each Ridge Grappler tire features two unique sidewall designs. One side is more traditional while the other features a more aggressive block design.
El neumático Ridge Grappler de Nitto pertenece a la categoría: Todoterreno Resistente y fue desarrollado para conductores de vehículos utilitarios deportivos (SUV, por sus siglas en inglés), Jeeps y picops, que buscan un neumático versátil y estilizado, capaz y duradero, tanto para condiciones todoterreno, como cómodo en los autopistas.
El compuesto de caucho durable del Ridge Grappler es moldeado en una huella de patrón simétrico, que cuenta con bloques robustos, reforzados con bordes cónicos, estos, optimizan el contacto con la superficie, para obtener una tracción competente sobre superficies secas. Bloques en la huella con tonos de sonido variables con diferencias de tamaños leves, reducen el ruido de la carretera para aumentar el confort al conducir en estas. Bloques con bordes escalonados y tacos en los hombros se combinan, para proporcionar características ventajosas a través de muchos ambientes todoterreno. El patrón lateral con surcos en zigzag proporciona una evacuación de agua eficiente a los canales de los hombros, mientras que pequeñas ranuras en los bloques de la huella, ayudan a resistir el deslizamiento sobre agua (hydroplaning) y asistir con la tracción sobre superficies mojadas. Mayor espacio entre los bloques y gran cantidad de bordes adherentes proporcionan una tracción confiable sobre superficies con poca nieve.
La construcción interna del Ridge Grappler posee una estructura reforzada con dos capas de poliéster que aumentan la durabilidad y comodidad del andar. Dos correas de acero con resistencia a tensiones fuertes, ofrecen una fundación sólida, para distribuir el peso a través de toda la huella. Dos capas de refuerzo de nailon aumentan, aún más, la estabilidad de la huella para obtener mejor maniobrabilidad y durabilidad por su uso a velocidades rápidas.
Como todos los neumáticos Grappler, cada neumático Ridge Grappler ofrece dos diseños únicos del flanco, uno tradicional y otro más agresivo.

Recently installed a set of the Cooper Discoverer Road and Trail AT on my Cherokee. The dry traction is impressive, providing a stable and confident feel on highways and city streets, while its wet traction is equally reliable. The tire grips well in wet conditions, which gives me the confidence for safe handling on rain-soaked roads without slipping or hydroplaning. One of the features that initially stood out is its ride comfort; the tire absorbs road imperfections smoothly, delivering a quieter, more relaxed driving experience compared to the other all-terrain tires I've driven on. The Cooper is also a rated for Severe Snow with the 3 peak mountain snow flake symbol, and I look forward to see how well they do in the winter time. The tire looks great on a Jeep as well.

...Wet traction is good, hydroplaning is satisfactory...
Overall, I like these tires. Everyday driving they're comfortable and quiet. I've used them in Moab on moderate/ slightly difficult 4x4 trails (it's a cherokee trailhawk, not a rubicon) and had no issues. Also have used them pretty extensively on Colorado 4x4 trails and forest service roads in slight mud and packed to overnight fresh fluff snow with no problems. I have not had an opportunity to really test them in nasty conditions yet. I do have slight concern in really icy conditions on the road and I did almost slip right through an intersection on black ice, but normal crappy snowstorm conditions on I70 through the CO mountains I've had no problems. They seems to have worn more than I've expected, as with Coopers I've had before on a previous vehicle, I really don't think I'm going to get the full mileage out of them as I did the stock Firestone Destination A/T. I've rotated them twice and keep them up to pressure during normal day-to- day. I do air them down when offroading, but not drastically. Overall they have been great tires though. Wet traction is good, hydroplaning is satisfactory. I don't think my cherokee trailhawk will see another set of tires under my ownership, but I wouldn't argue with another set of these tires.

Tire performs well and is used 90% on road with regular off road weekend trips. Excellent grip in all conditions on road, also performs exactly as needed off road and in adverse weather in the NW.

Only problem is that after 20k miles I'm down to 9/32nds putting me on pace to be all used up (4/32nd) at 45k miles compared to the 65k rating. That will only give me 2 winters of use which is pretty sad. I will probably switch to Falken Wildpeak AT4W even though I like the quietness and wet weather grip of the Cooper R&T.

...These got me through the Buffalo 2024 blizzard that pushed the playoff game. Easily 2" or more of snow on road for over an hour, not once did I slide (of course, with reasonable driving)...
Fantastic set of tires. Went to these from the Cooper AT3 XLTs that had some interesting wear. Very pleased with the performance all around. Never pushed these to their limit, but great in dry, wet, and snow. These got me through and out of the Buffalo 2024 blizzard that pushed the playoff game. Easily 2” or more of snow on road for over an hour, not once did I slide (of course, with reasonable driving). Still look brand new with almost new tread depth after 11k miles and 2 rotations.

...Good dry and wet pavement handling, good when pushing them thru corners and switchbacks on mountain roads out West and handled the mountain snow packed mountain roads with ease...
I have had this same tire on my Ram 1500, liked them, saw they were made in a size for my Subaru when I needed tires, and bought them. I have experienced good all around performance and OK mileage on my truck, and am on my second set there. Got about 35K from the first set on my truck, a good bit short of the mileage promised in their advertisements, but for the price, still considered them a decent value. I have 17K on these tires for my Subaru and am pleased with performance and tread wear. Good dry and wet pavement handling, good when pushing them thru corners and switchbacks on mountain roads out West and handled the mountain snow packed mountain roads with ease. I like the tires on both my truck and Subaru, get good all around performances and am not unhappy with tread wear. Will probably purchase again.

...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.

These Cooper tires have been a HUGE, step up over the factory Goodyear tires. The tires are very quiet, and the truck rides very nicely now. They have performed very well, while trailer a boat too. These were a new tire model, that was recommended by my advisor. His recommendation was spot on! Tire rack as always is the best tire supplier in the game.

...Treadwear has been outstanding...
Very impressive tire. These are extremely quiet and for a tread that is fairly aggressive. Treadwear has been outstanding. I ordered tires and wheels, the set arrived on time and the balancing was spot on. These tires have not had any vibrations. Great tire, I highly recommend.

...I had over 200,000 miles on sets of Hankook Dynapro AT2 and was consistenly disappointed...
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.

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.
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.
