Cooper Discoverer Tires

Cooper Tire & Rubber is one of America’s oldest tire manufacturers, with roots that date back to 1914, when they were founded as M&M Manufacturing in Akron, Ohio. Today, Cooper is still based in Ohio and still manufactures tires domestically, and includes sub-brands like Mastercraft, Starfire, and Mickey Thompson. For more than 30 years, the Cooper Discoverer family of tires has been a major presence in the world of all-terrain tires for light trucks, Jeeps, SUVs, and crossovers. Just the name “Discoverer” connotes an invitation to explore the ranch roads, oilfield lease roads, and rough rural backwoods of wherever you might be, with the confidence of knowing you’ll get where you want to go and back again safely.

With designs that are centered around the torque, weight, horsepower, handling, and performance of today’s light trucks, the Cooper Discoverer family is designed for dependable and durable off-road ability along with road manners, ride quality, handling, and overall composure on the pavement. They deliver a versatile, best-of-all-worlds balance that makes them a great choice for a wide variety of today’s trucks and SUVs. Let’s take a look at some of the top tires in the Discoverer lineup and what they have to offer:

Cooper Discoverer Stronghold AT

Cooper Discoverer Stronghold AT offers drivers a seamless blend of off-road durability and capability with pavement manners and secure, stable performance. It is a heavy-duty all-terrain tire that’s designed to meet the challenges of rough off-road conditions, city streets, and long hours on the interstate. The Discoverer Stronghold AT is designed with a tough 2-ply polyester casing, twin high-tensile steel belts, and a single-ply polyamide cap layer for durability, a forgiving ride, and great high-speed stability on the road. Its next-generation tread compound is designed for great wear properties along with toughness and great wet-weather traction. It showcases an aggressive all-terrain tread with wide grooves to grab and release soft surfaces while easily shedding any mud or gravel from the grooves, ensuring there’s always a clear section of the tread to dig in as the wheel turns.

Scooped tread edges and a hook at the sidewall ensure lateral traction for cornering or for clawing out of deep, muddy ruts. Cooper’s 3D sipe design and alternating textured edges at the shoulder help to multiply surface area and traction with hundreds of thin edges to dig in and claw through mud, snow, slush, or standing water, qualifying the Discoverer Stronghold AT for the 3 Peak Mountain Snowflake certification for severe winter service. Cooper covers the Discoverer Stronghold AT with a 60,000 mile limited manufacturer’s tread life warranty, as well as a 45-day satisfaction guarantee.

Cooper Discoverer Road+Trail AT

Here’s an all-terrain tire that’s just as at home and in its element in mud, snow, sand, and gravel as well as on an urban boulevard; the Cooper Discoverer Road+Trail AT. The Discoverer Road+Trail AT receives Cooper’s EnduraGuard construction tech package, consisting of a 2-ply polyester casing, twin steel belts, and a single-ply nylon reinforcement layer, all of which help the tire retain its shape and hold up in some of the roughest conditions and terrain you can send its way. Its aggressive all-terrain tread includes rugged interlocking tread blocks and alternating scoop/cleat lugs at the shoulder that extend down onto the sidewall (50% further than the tire’s predecessor) for enhanced lateral traction.

Deep, wide circumferential grooves and lateral notches help resist hydroplaning, and zigzag sipes at the shoulder give the Discoverer Road+Trail AT the traction it needs for the 3 Peak Mountain Snowflake rating for severe winter service. Cooper covers the Discoverer Road+Trail AT with a 65,000 mile limited manufacturer’s tread life warranty and a 45-day satisfaction guarantee.

Cooper Discoverer STT Pro

In the world of tough mud-terrain tires, the Cooper Discoverer STT Pro is a real standout. Cooper’s Armor-Tek3 construction technology gives the Discoverer STT Pro an added measure of toughness and stability; while most 3-ply construction methods use all three plies oriented at about the same angle, Cooper’s innovative Armor-Tek 3 lays down the third layer at a slightly different angle, cutting the number of weak points in the tire’s tread and sidewall for real durability. Its aggressive high-void all-terrain tread offers drivers deep tread depth with mud-release dimples in the lugs and anti-stone retention ribs to quickly rid tread grooves of mud, gravel, and debris to enhance traction and protect the casing from damage. Its center section uses a unique block pattern for better road manners and stability, and Cooper’s Earth Diggers lug/scoop design at the shoulder improves grip in deep mud, dirt, or sand. The Rock Climber Sidewall is designed with flex grooves and “climber cleats” that help the mud-terrain tire claw its way over rough and steep terrain while being aired-down for rock crawling.

Cooper Discoverer A/T3 4S

The Discoverer AT3 4S from Cooper is designed to do it all, where ‘all’ includes long interstate road trips, back-and-forth work commutes, rough and challenging off-road conditions, and severe winter weather. The Discoverer AT3 4S features AquaVac channels in the tread to route water away from the tire’s contact patch and resist hydroplaning, and a specially designed 5-rib all-terrain tread enhances off-road traction in difficult terrain. Micro-Gauge zigzag sipes bite into slippery surfaces, snow, or slush for confident grip, and Cooper’s Snow Groove Technology traps and retains snow in the tread to build snow-on-snow friction in winter weather. That pays off with winter braking distances that are shorter by as much as 20 feet and earning the Cooper Discoverer AT3 4S the 3 Peak Mountain Snowflake certification for severe winter service. On the highway, the tread pitch of this all-terrain tire is randomized and computer-tuned for low road noise, canceling certain frequencies and overtones for a quiet ride.

Cooper Discoverer TrueNorth

For serious winter weather (the kind of weather where several inches of snow might linger on the roads for days), all-season tires are usually just not going to be up to the job. That’s when you need a dedicated winter tire like the Cooper Discoverer TrueNorth. The Discoverer True North is a premium winter tire with a studless design and a specialized winter tread compound that stays flexible for traction in subfreezing weather (like all winter tires, the Discoverer TrueNorth will wear quickly on warmer days and shouldn’t be used if temperatures are above 40-45 degrees F). Its asymmetric winter tread includes a dense network of sipes to slice through snow and slush, and Cooper’s SnowGroove design that traps and retains snow to develop snow--on-snow friction in severe winter weather. Noise-dampening technology helps to ensure a quiet ride on the highway, and the Discoverer TrueNorth has both the M+S rating for mud/snow traction and the 3 Peak Mountain Snowflake certification for severe winter service.
