“I have them on my 12' 2500 with a Hemi work pickup. I have a little over 15,000 miles on them and they are holding up great. They are a little noisy on the pavement but they are a mud tread.”

Tire A
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.

“My new tires. Cooper Discoverer STT PRO”

“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.
Community buzz from Reddit and forums is shown for context only — it never changes the score.
