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.

“Interesting, I'm considering a Cooper Discoverer A/T3 Sport or Discoverer S/T Maxx in 245/70r16 for my Nissan. All of the reviews are excellent and have been recommended from friends using both types, one on little Suzuki Jimny and one on GC 2.7 diesel. According to them they are great both on pavement and off road, with GC driver being long time off roader.”

“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 .”

“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.”

Tire B
Positive
Cooper Discoverer STT PRO
Community members widely praise the Cooper Discoverer STT PRO for its exceptional off-road traction, towing capability, and dependable handling in mud, rain, and snow. While users note it balances well and rides comfortably for a mud-terrain tire, the most common criticisms involve pavement road noise that increases with wear and concerns regarding tread life on heavy trucks.

“I have never been let down by Cooper Discoverer STT PRO or BFGoodrich KO2 off road tires. I love the traction the Cooper STT PRO give me off-roading in the desert. I drove on KO2 from the 2018 until I got my STT PRO. I had Firestone’s as original equipment on a couple different vehicles and never had so many flats (on road or off road).”

“I thought I'd throw my two cents in! I put 5 Cooper Discoverer STT Pro tires on my 2015 Nissan Xterra Pro-4 X in 2021. It cannot be overstated - I LOVE these tires! They're great in dry conditions, they're great in the rain, they're great in the snow, they're great on ice - they even drove over a frozen iceberg in my driveway during a winter emergency as though it wasn't even there. There's a little bit of road noise, but nothing terrible. You can definitely "feel" them when you're driving - but I kind of like that. My truck sits outside during all kinds of Ohio weather, and they don't appear to be cracking/dry rotting quite yet. It will technically be "due" for me to get a new set of tires next year. Without a doubt, I'm getting another set of these!! Happy trails, all!”

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.
