The Cooper Discoverer STT is widely praised by truck and SUV owners for its exceptional off-road performance, aggressive appearance, and surprisingly manageable on-road manners for a mud-terrain tire. While a few users noted issues with tread wear or increased road noise over time, the overwhelming majority report high satisfaction, strong durability, and repeat purchases.
What owners say
No road-test results yet, so every score here comes from owner reviews found online.
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
45/100From 49 owner reviews analysed, scaled like the road tests: the average tested tire gets 70.

The Cooper Discoverer STT is widely praised by truck and SUV owners for its exceptional off-road performance, aggressive appearance, and surprisingly manageable on-road manners for a mud-terrain tire. While a few users noted issues with tread wear or increased road noise over time, the overwhelming majority report high satisfaction, strong durability, and repeat purchases.
Pros
- Exceptional off-road traction in deep mud, sand, rocks, and snow
- Surprisingly smooth ride and stable handling on paved highways for an aggressive mud tire
- Strong, durable 10-ply (Load Range E) construction with robust sidewalls
- Impressive tread life and mileage longevity compared to competitors
- Aggressive, head-turning tread design that cleans out well
Cons
- Increased road noise as the tires wear down, typical of mud-terrain tires
- Some reports of faster-than-expected or uneven tread wear for certain drivers
- Noticeable drop in fuel economy (MPG) on lighter trucks
- Slightly heavy construction requiring careful balancing and higher PSI for heavy-duty applications
Worth knowing
- Heavy-duty truck owners (such as Ram 2500 and Chevy K2500 diesel models) praised the Load Range E 10-ply tires for handling heavy towing and snow plowing exceptionally well at 80 PSI.
- Lighter vehicles like the Toyota Tacoma experienced a noticeable drop in fuel economy after installation.
- Jeep Wrangler and older Tahoe owners highlighted great ride comfort and predictable off-road handling, particularly on 16-inch and 35-inch setups.
