“I put Cooper CS5 Grand Tourings on my Sienna after having gone through several sets of Michelins, I am happy with them so far. Regardless of what tire you purchase, they will not get to their warranty mileage on a Sienna. The Sienna is notoriously hard on tires. A word of advice, run them at 40 to 42 PSI and rotate them regularly if you want to get reasonable wear. The Sienna's 35 PSI recommendation is FAR too low for the weight the tires carry and the front tires wear 3x faster than the rears.”

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.
Discoverer SRX
CS5 Grand Touring
Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
From Reddit, forums and review threads. Not part of our score
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.
“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...”
“I just put the Cooper SRX on my 2013 Overland, nice and quiet so far. The snow has been easy too, I don't foresee having any problems with these tires, glad I got them.”
“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.”

Community sentiment toward the Cooper CS5 Grand Touring is largely positive, with owners highlighting its smooth ride, low road noise, and reliable all-season traction in rain and light snow. While praised as a strong value compared to premium competitors like Michelin, several users note that treadwear often falls short of the advertised 80,000-mile warranty, particularly on heavier minivans or under high-heat conditions.
“My wife and I have been running Cooper CS5 Grand Touring on Outback and Impreza for many years. (the Outback is on its 2nd set) For us, having a QUIET tire is primary importance... followed closely with winter-traction here in Vermont winters. We do NOT want to have 2nd set of dedicated snow-tires for the winter. The CS5 have met our requirements. At the very least, I would suggest you consider the CS5 Ultra as you make a decision.”
“I have the Cooper cs5 grand touring on my Odyssey and love them. Very quiet and snoot riding. Fwiw, I'm in Southern California so we have little cold/wet weather let alone snow, but they did great when I drove up to Sequoia and had cables on during the snow storm. Much better than the Michelin Defenders I had before.”
“I too was looking for quiet tires when it came time to replace. Have been very happy with COOPER CS5 GRAND TOURING ==> The CS5 has many modern technologies which improve longevity and traction AND they are M+S rated. I run them all year in Vermont and the snow traction is acceptable with Subaru AWD.”

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.
