Two scoring systems, side by side
Owner scores come from reviews found online; road-test scores come from instrumented tests. Where they disagree, it is usually a discipline owners rarely push to the limit.
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
67/100From 7 owner reviews analysed, scaled like the road tests: the average tested tire gets 70.
By road tests
62/100Scaled across every tested tire: the average gets 70, the best 100.

The Cooper Discoverer Stronghold A/T generally receives favorable feedback from users for its impressive all-weather traction, solid heavy-duty capability, and strong value proposition compared to competitors. While most drivers praise its dry handling, snow performance, and towing stability, a minority of users note issues with road noise and steering wander.
Pros
- Exceptional traction in snow, ice, and winter conditions
- Great capability for heavy-duty towing and plowing
- Affordable pricing compared to premium alternatives like Nitto
- Smooth and predictable handling on dry pavement
Cons
- Noticeable road noise at higher speeds for some users
- Occasional reports of steering wander compared to older models like the AT3 XLT
Worth knowing
- Users running heavy-duty trucks (e.g., GMC Sierra 3500HD and Ram 1500) highlighted strong performance when towing heavy loads or plowing snow.
- Larger sizes such as 295/70/18 and 275/65R20 received specific praise for balance and real-world utility.
