Pros, cons & observations
Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
Tire A Discoverer S/T Maxx
Pros
- Aggressive all-terrain tread pattern that excels in dirt, gravel, sand, and moderate mud
- Surprisingly quiet and smooth ride on the highway for such a rugged tire
- Exceptional sidewall strength and puncture resistance against sharp rocks and debris
Cons
- Faster-than-expected tread wear for some users, particularly on heavier duty or lighter vehicles
- Subpar wet pavement traction, specifically in cold or greasy conditions
- Stiff ride quality and potential handling vagueness or steering pull if pressures are not meticulously tuned
Tire B Open Country WT
Pros
- Exceptional performance and traction in snow, ice, slush, and wet weather
- Surprising longevity and slow tread wear over high mileage (20,000 to 30,000 miles)
- Good versatility and capability for light off-road use, unmade tracks, and muddy fields
Cons
- Slightly increased road noise compared to standard road tires, though not overly intrusive

Tire A
Positive
Cooper Discoverer S/T Maxx
The community generally praises the Cooper Discoverer S/T Maxx for its exceptional dual-purpose performance, offering low road noise and strong traction across various off-road conditions like mud, rocks, and sand. Users note good handling while towing heavy loads, though some mention a slight softness or different feel during cornering that does not negatively impact overall safety. While initial purchase costs can be high, overall satisfaction is very high with many loyal repeat customers.

“I have 285/75-r16 on my f-150 and love them. I've put them through hell (rocks, mud, sand, rim breaking in half and truck skidding down the road on it) and the have held up amazing. My old set of cooper st's last around 60k and still had a little life left. Ill never run any thing but coopers now. and for the record i had that tire checked out by 3 different tire shops and they all said it was fine.”

“I have the 285/75-16 Discoverer MAXX on my 05 CCSB and I love them. They ride nice, are quiet and work well when hauling my Tractor . As far as the feeling when turning they do feel a little different but it has not affected the handeling of the truck at all. I def . recommend getting this tire .”

How do we compare tires?
Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.
Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
