“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.”

- Surprisingly low road noise and smooth ride for a mud-terrain tire

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 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.
