Higher is better. The Relative Score follows your weights below; category scores do not change.
Wet grip starts at “Important”. Treadwear starts at “Neutral” here: road tests measured it for at most one of the two tires, so it rests on owner reviews. Move the sliders and the scores update instantly.

Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
From Reddit, forums and review threads. Not part of our score
The community views the Cooper Discoverer SRX as a quiet, comfortable, good-value all-season CUV/light-truck tire. Owners often report better-than-expected snow traction, stable handling and good wear, with several users recommending it over the Cooper CS5 and Michelin alternatives on price. A few reservations appear: one owner got only about 40,000 miles, and its weight (about 31 lbs) was noted in a lighter-tire discussion.
“Tire recommendations that are lighter than Wildpeaks BLUF: Looking for an off-road capable tire (225/65R17) that doesn't weigh as much as a Falken Wildpeak. I'm aware off-road tires weigh more by design -- beefy treads, blocks, and sidewalls come at a cost weight-wise. That much I understand. That said, Falken Wildpeaks (30 lbs), Geolandar A/T G015s (30.3 lbs), Toyo Open Country A/T III (32 lbs) and even something more mild like a Cooper Discoverer SRX (31 lbs) represent a nearly 25% increase in rotational mass (I think that is the correct term) over the stock Dueler H/P Sport AS tires, and therefore will drag down MPGs and wear on the drivetrain a bit more over time. Is anyone aware of AT or AT-style tires that are fairly close to the OEM tire weight? Did anyone else shopping for tires take weight into account? I'm not in need of something super aggressive, but I do like to take on mild to moderate trails at the local OHV park, as well as the occasional dirt road overloading trip. The Pirelli Scorpion All Terrain Plus is at least under 30 at 29 lbs, as is the 28 lbs Cooper Discoverer EnduraMax which integrates "all-terrain tire technology" according to the TireRack page. And the Firestone Destination LE 2 only weighs 24 lbs, and the LE 3 is 23 lbs. but I'm not sure how off-road capable those tires are. Thank you, this has been my Ted Talk. Read more”

“I've been running the Discoverer SRX on my 2014 Highlander for the last few years (40,000 miles) and they are still very quiet. Better than I expected in the Winter, too. I used to run dedicated snow tires and knew that an AS tire would not be as good but was pleasantly surprised by the Winter performance.”
Based on 30 community posts
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.”
“Personally a huge fan of the Cooper Discoverer S/T Maxx great on and offroad. Quite on road.”
“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.”

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.
