From owners
Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Avon ZT7 is generally regarded as a budget-friendly, comfortable tire that performs adequately for daily commuting and standard driving conditions. While many users praise its quiet ride and impressive value, a significant portion of the user base reports concerns regarding premature sidewall cracking and inconsistent performance during spirited driving.
Pros
- High value for money compared to premium brands
- Impressively quiet and comfortable ride quality
- Reliable wet and dry grip for standard, non-aggressive driving
- Good tread longevity for many users
Cons
- Frequent reports of premature sidewall perishing or cracking
- Tendency to understeer when pushed hard in corners
- Inconsistent handling characteristics under spirited driving
- Reports of uneven tread wear in some applications
Observations
- Users operating small, lightweight vehicles report the tire is sufficient for daily use but lacks the precision required for spirited driving.
- Fleet van operators find the tire durable and quiet, suggesting it performs well under consistent, moderate commercial use.
The Kumho Ecowing ES31 is widely regarded as a high-value, budget-friendly tire that excels in comfort, noise reduction, and fuel efficiency. While many users report satisfactory performance in both dry and wet conditions, a notable segment of reviewers expresses significant concerns regarding wet-weather grip and sidewall stability, suggesting it is best suited for conservative, daily driving rather than spirited maneuvers.
Pros
- Excellent value for money compared to premium brands
- Noticeable reduction in road noise and improved ride comfort
- Positive impact on fuel economy and rolling resistance
- Strong dry-weather handling and responsiveness
Cons
- Inconsistent or poor grip in wet conditions for some users
- Soft sidewalls leading to a lack of precision during cornering or lane changes
- Reports of premature or uneven tread wear in specific cases
- Susceptibility to sidewall damage from potholes or curbs
Observations
- Users driving smaller hatchbacks and city cars frequently praise the tire for its comfort and noise levels during daily commuting.
- Drivers of heavier or more performance-oriented vehicles occasionally report that the soft sidewalls cause a 'pitching' sensation during aggressive steering inputs.
- Some users noted that the tire's performance in wet braking can feel compromised, particularly on smaller, lighter vehicles.

“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.”

“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 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.”

How do we compare tires?
Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements) normalized against the best tire in each test and weighted toward recent tests. 40% comes from thousands of owner reviews collected from retailers and review sites. When a tire has only one of the two, we use what exists and say so.
