“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.”

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.
Only one of the two tires has a score here, so this weight changes nothing in the head-to-head.

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.
“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.”
“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.”
“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.”

The Kumho Ecowing ES31 is generally viewed as an affordable, budget-friendly mid-range summer tire that offers good durability and dry grip, making it popular among commuters and rideshare drivers. However, opinions are mixed regarding its wet weather performance, with some users reporting poor wet grip while others find it acceptable for cautious, everyday driving.
“Certa vez, nos comentários de um vídeo sobre pneus no YouTube, vi a galera que trabalha com Uber falando bem do Ecowing ES31, relatando que tem ótima durabilidade. Resolvi arriscar e coloquei, são ótimos mesmo, já rodei 18 mil km e estão impecáveis ainda.”
“The EU label is all over the place. But none have A-A-A as far as I can tell. Did not score good in wet in the test on the site. Wear rate on a Mazda 2 should be decent with almost anything. Why not look at all seasons? Sava All weather and Kumho Solus are closest to the ES31 in price.”
“ES31s are fine, they're your usual budget tyre. Certainly not meant for any spirited driving or for sport type cars. I've had them before on the front my my Yaris and they were acceptable, got maybe 40,000km out of them.”

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.
