Tire A

Cooper Discoverer STT PRO

Positive

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.

“Installed the stt pro's on the 10 duramax , so far I really like the tires . Put them to the test backcountry camping (towing 5th wheel) & they were good in the mud & towing. They arent the quietest tires , but did quiet down after some miles. Comparable in noise to the trail grapplers or slightly louder, they weren't squirmy when new, unlike the trailer grapplers I had on my old dodge diesel for the 1st few hundred miles Sent from AutoGuide.com Free App”

“I have used Cooper Discoverer STT Pro's in mud, rain, snow, ice, sand, etc. They have performed just fine in each. They are a bit louder on the highway, but it's not that noticable. -jokester”

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.
