The Dunlop Grandtrek ST20 is generally regarded as a reliable and durable original equipment tire, particularly favored by owners of compact and mid-size SUVs. While users consistently praise its longevity and predictable handling in mixed weather conditions, some report concerns regarding sidewall cracking over time and a noticeable decline in wet-weather performance as the tread depth approaches the legal limit.
What owners say
No road-test results yet, so every score here comes from owner reviews found online.
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
70/100From 9 owner reviews analysed, scaled like the road tests: the average tested tire gets 70.

The Dunlop Grandtrek ST20 is generally regarded as a reliable and durable original equipment tire, particularly favored by owners of compact and mid-size SUVs. While users consistently praise its longevity and predictable handling in mixed weather conditions, some report concerns regarding sidewall cracking over time and a noticeable decline in wet-weather performance as the tread depth approaches the legal limit.
Pros
- Impressive tread life and overall durability
- Consistent and predictable handling in mixed weather conditions
- Strong performance for light off-road and towing applications
- Good value proposition as an original equipment replacement
Cons
- Noticeable reduction in wet grip at lower tread depths (below 3mm)
- Tendency for sidewalls to develop cracks or crazing over time
- Increased road noise on rough or concrete surfaces
- Uneven shoulder wear reported by some users
Worth knowing
- Owners of shorter-wheelbase vehicles like the Daihatsu Terios noted potential bounciness, though it was unclear if this was tire-specific or vehicle-geometry related.
- The tire is frequently cited as a preferred original equipment choice for Nissan SUVs, with users often opting to repurchase the same model after the initial set wears out.
