Two scoring systems, side by side
Owner scores come from reviews found online; road-test scores come from instrumented tests. Where they disagree, it is usually a discipline owners rarely push to the limit.
How scores work
- Relative score
- 0–100. Blends road tests (60%) and owner reviews (40%) category by category, the same way on every TireWheelGuide page. With only one of the two, the missing half is estimated from it, so the score stays closer to average. It needs at least one road test or five owner reviews.
- Road tests
- 0–100 per score, from published tests, newer tests counting more. Each result is compared with every other tire in the same test, so a win against a strong field counts for more. The average tested tire gets 70, the best 100; with only one or two tests a tire stays nearer 70. The discipline rows show % of the best tire in that test.
- Owner reviews
- 0–100 from the owner reviews we found online, adjusted for how generously each site rates and scaled like the road tests: the average tested tire gets 70. With only a few reviews a tire stays near the average.
By owner reviews
34/100From 3 owner reviews analysed, scaled like the road tests: the average tested tire gets 70.
By road tests
66/100Scaled across every tested tire: the average gets 70, the best 100.
What owners like and dislike
Themes extracted from 3 owner reviews found online.
The Sunny NA305 receives predominantly negative feedback from users, who cite severe deficiencies in wet weather performance and exceptionally rapid tread wear. While a few drivers note acceptable dry handling and fuel efficiency relative to its low price point, the overwhelming consensus points to poor safety margins and inadequate durability.
Pros
- Affordable budget-friendly price point
- Acceptable dry weather handling and feel for basic driving
- Good fuel consumption and rolling resistance characteristics
Cons
- Extremely poor wet weather traction and cornering grip
- Shockingly fast tread wear requiring replacement in under 5,000 miles
- Lackluster feedback and twitchy driving dynamics
- Excessive squealing during normal dry cornering
Worth knowing
- Budget-focused purchasers utilizing the tire for standard daily commuting or to pass a vehicle inspection found the longevity entirely inadequate, with front tires wearing out prematurely on standard passenger vehicles like the Nissan.
