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”
ford-trucks.com
“I run a set of Nankang Mudstar tires on my 94 F350, also overseas cheap MTs. For the price, they are about what you'd expect. Very loud, very rough riding, wear fairly quickly. But they were like $600 shipped to my door for a set of 315/75R16, E load range. On my 89 F350 that I drive more often and pull trailers with, I have a set of Cooper Discoverer STT Pros. Night and day difference, but I can buy 2 sets of Nankangs for the cost of 1 set of Coopers. I don't know that I'd risk cheaper tires on my daily driver though. That being said, I do like the look of those Crosswinds.”

“I ran them on my Cherokee for a year. Awesome tire aside from icy roads. I loved the tires off road, They just didnt have enough siping to contend with slippery pavement. Went back to the STT MAXX and had no issues.”

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.
