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
77/100From 172 owner reviews analysed, scaled like the road tests: the average tested tire gets 70.
By road tests
65/100Scaled across every tested tire: the average gets 70, the best 100.
What owners like and dislike
Themes extracted from 172 owner reviews found online.
The Cooper Discoverer Rugged Trek receives predominantly positive feedback from truck and SUV owners who praise its aggressive styling, surprisingly quiet highway ride, and strong traction in mud, snow, and rain. Many users draw favorable comparisons to competing all-terrain and mud-terrain tires, noting better comfort and lower noise levels than popular alternatives like BFGoodrich KO2.
Pros
- Aggressive and appealing tread design that looks like a hybrid between an all-terrain and mud-terrain tire
- Surprisingly low road noise for such an aggressive tread pattern
- Strong off-road traction in mud, sand, dirt roads, and rocky terrain
- Exceptional winter weather performance with solid snow grip and 3-peak mountain snowflake rating
- Good towing stability and heavy-duty load handling on trucks
Cons
- Slight decrease in fuel economy (typically a 1 to 4 MPG drop)
- Some road noise and humming that can increase as the tires wear down
- Limited ice traction compared to dedicated winter tires
- Occasional reports of balancing difficulties or road force issues during installation
- Some users noted the tread picks up a lot of gravel
Worth knowing
- Users running 10-ply variants on heavy-duty trucks (like Ford F-250s and Chevy 2500HDs) reported stable towing performance and a ride quality that remains surprisingly comfortable for a heavy-duty tire.
- Owners running lower-profile configurations on large rims (such as 22-inch wheels) noted a slight firming of the ride and a faint humming noise, but remained impressed by the overall comfort.
- Mid-sized and full-sized SUV and truck owners (such as Toyota 4Runners and Tundras) frequently praised the balance of highway manners and off-road capability.
