“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.”

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.

This implied a ~3% lower noise level on the EGP tyres: Although it is ~3% dB over dB, considering that 3dB corresponds to 2x loudness, the reduction may be more significant than what the number suggests.”
“GOODYEAR EfficientGrip Performance 205/55 R17 91V - reliability and resistance to damage question Hello guys! I'm driving Skoda Octavia. not a racer, just a usual 40yo man. I have a set of GOODYEAR EfficientGrip Performance 205/55 R17 91V on the car, and during the last 2 months I lost three tires, all the same way - pothole on the road, visibly small, front right wheel, instantly deflates, and a hole in tire not on tread but on the side - irreparable, new tire for 130eur, repeat again. Do you by chance know if it's the pattern for the model, or am I getting EXTREMELY unlucky? Can you maybe suggest some tire models and characteristics to look into to stop this from happening? I have only 2 out of 4 original tires left, so maybe it makes sense to change the entire set. Read more”

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.
“Kumho ecowing es31 é o melhor custo benefício, tem classificação B de consumo e C de aderência, eu já tive pneu da Kumho e gostei da aderência e é um pneu macio pra conforto. Continental Power Contact 2 tbm é uma boa opção. Eu não recomendo xbri, farroad, ling long, speedmax, pois tem durabilidade baixa.”
“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.”
“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.”

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.
