Cooper Discoverer Road + Trail A/T Review (Detailed)

Introducing the Cooper Discoverer Road+Trail AT, featuring an aggressive sidewall design and cutting-edge technologies. This all-terrain tire promises great reliability for various vehicles.
Design Highlights:
Tread Design: Road-oriented yet aggressively symmetrical with five distinct ribs.
Central Ribs: Unique block configurations with offset edges and sharp, saw-toothed snow vices for enhanced snow grip.
Curved Linear Sipes: Found in central ribs for better traction and stability, with adjacent ribs featuring laterally oriented sipes and snow vices.
Shoulders: Wave-like sipes, chamfered edges, and notches, interconnected by "whisper grooves."
Outer Edges: Staggered lugs with robust sidewalls, impressive for highway performance.
Dry Traction:
-Directional Grip: Assessed by braking distances. The compact central rib and robust foundational supports ensure optimal road contact.
Stickier composition and strategic notches enhance straight-line traction. Tests show that the Cooper Discoverer Road+Trail A/T stops half a foot shorter than its predecessor.
-Dry Handling: Combines lateral grip and steering responsiveness. Provides sufficient lateral traction, but steering responsiveness could improve due to the tire's substantial weight. Still performs better than the Cooper Discoverer AT3 4S.
Wet Traction and Handling:
Cooper Road+Trail A/T excels in wet braking, handling, and steering feedback with a mix of linear and wave-like sipes and numerous biting edges.
In tests, it outperformed the AT3 4S by over a foot in wet braking and was half a second faster in wet handling laps.
Winter Performance:
Winter Grip Technology: Earns both the 3 Peak Mountain Snowflake and M+S (Mud and Snow) ratings. Silica-rich, softer rubber composition and numerous sipes effectively grip icy and powdery snowy surfaces.
Noise Comfort:
Performance on Different Surfaces: Acceptable noise levels on rougher surfaces like cross-cut concrete. Needs improvement on smoother pavements, where it emits noticeable, cyclical noise.
Mitigation Efforts: Pitch Sequencing Technology helps reduce in-groove resonance by varying tire lug angles, producing different sound frequencies to reduce echo within the tread walls.
Fuel Economy:
EnduraGuard Design, intended for durable internal construction, results in increased tire weight, affecting fuel efficiency.
The pliant rubber compound, optimized for winter and wet performance, causes tire lugs to bend more easily, dissipating energy as heat.
These elements enhance durability and performance but reduce fuel efficiency slightly.
Muddy Conditions:
Features wide grooves and self-cleaning capabilities to prevent tread clogging. Best suited for lighter, less challenging mud.
Rocky Terrains:
Interconnected groove structure and independent lugs with offset edges provide good grip from various angles.
Supported by EnduraGuard technology for added durability. Suitable for lighter rocky trails but may not match the ruggedness needed for tougher environments compared to options like the BF Goodrich KO3.
Sandy Surfaces:
Softer, silica-rich tread allows more rubber to contact the ground, especially at lower air pressures. Sidewalls flex to enlarge the contact patch, distributing the vehicle's weight more evenly to prevent sinking. Slightly heavier weight could be a drawback in very deep sand.
Overall, the Cooper Road+Trail offers reliable performance across a range of off-road conditions but excels most on less demanding terrains.

Just priced out a set for my Ram 1500 Bighorn.
Will likely get them, as I have had very positive experiences with Cooper in the past.
Good review!

[@comparethetire]

Thanks for the feedback. Do share your experience here when you get them.

[@VINNY5674]

Great video
I own the AT3 XLT and totally love them. I am considering these on my grand jeep cherokee
Cooper makes excellent tires..

[@comparethetire]

Couldn't agree more! And thanks for liking the video.

[@benstone1308]

How do these compare to the BFG Trail Terrain?

[@comparethetire]

BFG offers better winter, and gravel performance. And while both tires have similar dry performance the Cooper Road + Trail offers better wet performance and overall ride comfort.

Misspelling: WHISPER grooves, not WISPER grooves.
I'm sure you meant snow VISES--gripping tool with movable jaws to grip and hold an object, and not snow VICES, bad and/or sinful habits.
Sipes dont hold water like a reservoir, it act like squeegees to squish out water and provide micro edges to grip on road imperfections.

[@comparethetire]

Vices is actually accurate but yes, you're right about the word Whisper. Thank you for letting us know man, really appreciate the feedback.

Good lord is that an AI voice?

[@comparethetire]

Nope, that's actually my voice!
