Cooper Discoverer Stronghold AT Tires
Meet the Cooper Discoverer Stronghold AT, an all terrain tire built to handle weekday commutes and weekend escapes. Its balanced tread delivers secure grip on dirt and gravel and keeps highway noise in check. A durable casing and cut and chip resistant rubber fight damage on rough roads, while full depth siping maintains wet and light snow traction as miles add up. It is backed by a 60,000 mile limited treadwear warranty and a 45 Day Test Drive, making it a smart, value forward pick for year round versatility.
Key Features & Technology
Stronghold AT pairs a versatile, all terrain tread with a road friendly ride. Multi angle tread blocks and open shoulders add bite on loose surfaces and push water aside for wet traction. Full depth, multi directional siping helps preserve braking and handling as the tire wears. Inside, a two ply polyester casing, two high strength steel belts, and a reinforcing polyamide layer add stability at speed, while a cut and chip resistant compound and stone ejecting grooves help fend off punctures on rocky trails.
On‑Road Comfort and Off‑Road Traction
On pavement, the Stronghold AT works to keep cabin noise down with a tread tuned for an even contact patch and fewer harmonic tones. Wide circumferential channels and lateral grooves evacuate water for confident braking in the wet. Off road, staggered shoulders and extra biting edges improve traction on gravel, dirt, and mild mud, and the cold weather compound and dense siping support light snow grip. For frequent deep snow or long stretches of ice, a dedicated winter tire is still the better choice.
Sizes, Fitment & Load Options
Popular Discoverer Stronghold AT sizes include 265/70R17, 275/70R18, 275/60R20, 285/70R17, 285/60R20, and 275/65R20, covering many late model trucks and crossovers. Match your vehicle's door jamb placard for overall diameter, load index, and speed rating. Many applications offer P metric for daily duty or LT options for heavier loads and towing, so choose based on how you use the vehicle. If you plan to upsize, verify fender and suspension clearance and have TPMS recalibrated as needed, and when in doubt consult your installer for an OE appropriate fit.
Durability, Warranty & Treadlife
A two ply polyester casing, twin steel belts, and a polyamide overlay give the Stronghold AT stable manners and resistance to impacts. Chip resistant rubber and stone ejectors help protect tread blocks on unpaved routes. Cooper backs the Discoverer Stronghold AT with a 60,000 mile limited treadwear warranty and a 45 Day Test Drive. Real world treadlife depends on rotation, alignment, load, and driving style, so rotate every 5,000 to 7,500 miles and maintain proper air pressure to maximize mileage.
Price & How to Buy
Pricing for the Cooper Discoverer Stronghold AT varies by size, load rating, and availability. Larger rim diameters and heavy duty load options typically cost more. For the best value, check current promotions, bundle installation, and plan an alignment to protect your investment.

Discoverer Stronghold AT vs Alternatives
Choosing all terrain tires often comes down to your priorities, whether that is on road quiet, winter performance, off road durability, or price. The Stronghold AT aims for a balanced mix with stable highway manners, dependable light snow traction, and off road readiness without excessive noise. When you compare options, look closely at warranty terms, construction details, winter symbols on the sidewall, and reported road noise. Match the tire's strengths to your driving and towing needs to decide with confidence.
Stronghold AT vs Falken Wildpeak AT4W
Both are modern all terrains built for mixed use. Stronghold AT focuses on a quiet highway ride with balanced off road grip and a 60,000 mile warranty, while Falken's Wildpeak AT4W leans into rugged trail traction and stronger winter capability. If everyday comfort and warranty length top your list, choose the Stronghold AT. If you want more aggressive shoulder bite for harsher trails, the Wildpeak AT4W may fit better.
Stronghold AT vs BFGoodrich All‑Terrain T/A KO3
The Stronghold AT is tuned for a composed daily drive with confident light off road use and a long treadwear warranty. BFGoodrich's All Terrain T/A KO3 is known for off road durability and aggressive traction. If most of your miles are highway with periodic gravel, camping roads, and light trails, the Stronghold AT delivers strong value and comfort. If you often air down, tackle rocky terrain, or need more sidewall bite, the KO3's off road focus can pay dividends, so compare load ratings, sidewall construction, and winter symbols in your size.
