Pros, cons & observations
Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.
Tire A Eagle F1 GS-D2
Pros
- Predictable and progressive grip loss characteristics
- Good initial wet weather traction and performance
- Suitable OEM fitment matching for light hatchbacks like the Suzuki Swift Sport
Cons
- High noise levels, particularly when cornering
- Compounds harden prematurely, leading to a severe loss of grip after extended mileage
- Poor rim protection design leading to vulnerable wheel edges
Tire B S Fit EQ+
Pros
- Good to excellent dry grip, traction and handling, with several reviewers noting stable, confident behavior
- Wet grip described as decent to excellent, with plenty of grip in both conditions
- Excellent value; frequently compared favorably with Continental, Goodyear, Michelin and Hankook tires at a much lower price
Cons
- Road noise noted as louder than expected by some reviewers, with one reporting a marked increase after 2,500 km
- Ride can feel stiff or harder than needed, and one reviewer found the tires became hard and uncomfortable below 10°C
- Longevity is uncertain; reviewers estimate roughly 18,000-20,000 miles from one set, and others are unsure how long they will last

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.
