“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.”

Tire B

Kumho Ecowing ES31

Mixed

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.

“The es31s are utter garbage in the wet. Good in the dry, and last a long time, but awful in the wet. Don't cheap out on tyres. I'd personally avoid most 'eco' tyres, they sacrifice a lot in grip and safety. The ecopia ep150 was class leading when it launched... in 2009. It's an ancient tyre that doesn't hold up anymore. Even worse than the es31s in basically everyway. If you have to get one of those two, DON'T get the ep150s.”

“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.”

“Tengo las kumho ecowing es31 y ninguna queja, siempre respondieron bien aunque la verdad manejo como un abuelo, solo una vez frene fuerte en la panamericana y nunca bloquearon, las volveria a poner en otro auto.”

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.
