Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
Not enough owner reviews yet to extract themes.
The Dunlop Grandtrek Touring AS receives poor feedback from users, primarily centered on significant concerns regarding structural integrity and premature material degradation. Owners frequently report issues with sidewall durability and rubber compound failure, leading to a lack of confidence in the product's longevity and safety.
Cons
- Premature sidewall cracking and rubber delamination
- Poor structural durability leading to blowouts upon impact
- Difficult and unresponsive customer service regarding warranty claims
- Concerns regarding quality control and potential faulty manufacturing batches
Observations
- Users report that tires often fail or require replacement well before the tread depth reaches the legal minimum limit.
- Multiple reports indicate that these tires, often supplied as original equipment, fail to meet the durability expectations of vehicle owners.

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.
Community buzz from Reddit and forums is shown for context only — it never changes the score.
