N Fera SU4
Pros, cons & observations
Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
Tire A Energy XM2+
Pros
- Strong wet performance: reviewers cite very good wet grip, effective displacement of deep water and puddles at 60-70 km/h, and no aquaplaning.
- Good dry grip and braking, with high lateral grip that allows confident cornering at higher speeds.
- Quiet, comfortable ride, described as 'silent & comfort' in several reviews.
Cons
- A thinner sidewall ratio was described as slightly bumpy, though stability and handling remained very good.
- Wet grip was rated lower than dry grip in the one reviewer who scored each category (7/10 wet versus 8/10 dry).
- Complaints are scarce and minor. Only the sidewall bumpiness and the relatively lower wet score count as negatives.
Tire B N Fera SU4
Pros
- Outstanding value for money compared to major premium brands
- High level of ride comfort and low road noise
- Reliable and predictable grip in both dry and wet conditions
Cons
- Softer sidewalls can lead to less precise steering feedback and body roll during aggressive cornering
- Average or faster-than-expected treadwear for some driving styles
- Can become harder and noisier as the tire ages or wears down

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.
