How scores work
- Relative score
- 0–100. Blends road tests (60%) and owner reviews (40%) category by category, the same way on every TireWheelGuide page. With only one of the two, the missing half is estimated from it, so the score stays closer to average. It needs at least one road test or five owner reviews.
- Road tests
- 0–100 per score, from published tests, newer tests counting more. Each result is compared with every other tire in the same test, so a win against a strong field counts for more. The average tested tire gets 70, the best 100; with only one or two tests a tire stays nearer 70. The discipline rows show % of the best tire in that test.
- Owner reviews
- 0–100 from the owner reviews we found online, adjusted for how generously each site rates and scaled like the road tests: the average tested tire gets 70. With only a few reviews a tire stays near the average.
By owner reviews
80/100From 800 owner reviews analysed, scaled like the road tests: the average tested tire gets 70.

The Cooper Discoverer A/T3 XLT is widely praised as a top-tier all-terrain tire, particularly for heavy-duty trucks and towing applications. Reviewers frequently compare them favorably against competitors like BFGoodrich, noting superior wet and winter traction, exceptional highway quietness, and robust towing stability.
Pros
- Significantly lower road noise than comparable aggressive all-terrain tires
- Excellent wet weather, snow, and slush traction
- Sturdy sidewalls and stable performance when towing heavy loads
- Aggressive, visually appealing tread and sidewall design
- Strong value and competitive pricing backed by a solid treadwear warranty
Cons
- Some users report difficulty with balancing, leading to vibrations or a rough ride
- Tread life occasionally falls short of expectations for certain drivers
- Can struggle or get gummed up in deep mud
- Ride can feel stiff or harsh on rough roads, especially with E-load/10-ply variants on heavy-duty trucks
Worth knowing
- E-load 10-ply variants mounted on heavy-duty trucks (such as Ram 2500 and Ford F-250) excel at handling heavy trailer weights and commercial use, though specific sizes like the 295/70R18 were noted by one user as being particularly unyielding on rough roads.
- Full-size truck owners (like Ford F-150 and Toyota Tundra) praise the tire for providing an aggressive look without sacrificing highway comfort or introducing excessive cabin noise.
