What real owners are saying

From Reddit, forums and review threads. Not part of our score

Tire A

Cooper Discoverer HT3

We haven't collected enough community discussion about this tire yet.

Tire B

Cooper Discoverer SRX

Positive

Community sentiment for the Cooper Discoverer SRX is overwhelmingly positive, with drivers consistently highlighting its quiet ride, comfortable handling, and dependable all-season traction. Many users report unexpectedly competent performance in light snow and winter conditions, along with favorable pricing compared to competitors like Michelin. Tread life feedback is generally solid, though at least one owner noted shorter longevity than expected.

“My wife is using the SRX in her 13' Explorer and so far I love them. Great stability, quiet, no hydro planing. Will update once get some snow in them. Sent from my iPhone using JeepGarage”

“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”

“We'd gotten Coopers on Wife's vehicle and were impressed, so I tried Discoverer SRX 245/65/R17 on our Honda Ridgeline truck and they were (and remain) a revelation at least in that they made a huge difference in quieting the road noise. This was 7 years ago and now 30,000+ miles later they still look as new with little noticeable tread wear. Dunno the HTP or ATP II versions but imo Coopers are/can be first-rate tires.”

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.
