“Cooper tires similarities Is the discoverer crossrange the new discoverer srx? I’ve had probably 4-5 sets of srx between current and previous cars and they all look exactly like this. Google says they are completely different tires but in terms of looks they are absolutely identical. 🤔”

Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
From Reddit, forums and review threads. Not part of our score
The Cooper Discoverer SRX is generally viewed as a reliable all-season highway tire, with users noting good past experiences and comparing them favorably or alternatively against competitors like Michelin. While some owners appreciate their performance for regular paved and light road driving, others note their weight impact relative to stock tires or debate their similarities to newer Cooper models.
“I’ve had Cooper Discoverer SRX (all-season) with good experience.”
“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”
“New tires.. for 2015 Limited 4WD....Michelin Defender LTX M/S vs Cooper Discoverer SRX I have had the Coopers for a while now but am looking to get a new set of tires. Should I go with them again or try out the Michelins? The Michelins seem to get good reviews and they're about the same price across both brands. What do you think? Mostly highway driving btw Read more”

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.
