Cooper Discoverer SRX
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.
“I have used the Cooper Discoverer SRX, the Cooper AT3 4S and Michelin Defender LTX. The Defenders lasted until 75000 miles and of course towards the end they were getting noisy and losing grip like all tires. Its a stiff tire built for longevity but not ride comfort. The Cooper Discoverer SRX is a very comfortable tire, but I got like 40000 miles out of them. They didnt seem to last. I am now using Cooper AT3 4S and its a very comfortable tire. It is a quiet tire but only a slight tolerable hum on the highway most wont notice. I cant believe its an all terrain tire. Thus I found long lasting does not translate to ride comfort. When you have a truck you need to hit the bumps more gently. The Coopers are comfortable tires which will make you turn your truck into a car but they are not 75000 mile tires. The Michelin Defenders will leave no doubt you driving a truck. For comfort also look at Continental/General line...”
“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”
“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”

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.
