From owners
Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
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.
The Toyo Proxes RA1 is widely regarded as a premier R-compound tire that balances exceptional track-day grip with surprising longevity. Users consistently praise its predictable handling characteristics and ability to maintain performance throughout the life of the tread, making it a favorite for both competitive racing and spirited street driving.
Pros
- Exceptional dry grip that remains consistent even as the tread wears down.
- Superior tire life compared to many other dedicated track-focused compounds.
- Predictable breakaway characteristics that provide driver confidence at the limit.
- Versatile performance, suitable for both track use and limited street driving.
Cons
- Performance can become 'greasy' if the tire is overdriven or overheated during long sessions.
- Requires proper heat cycling and break-in procedures to achieve optimal performance.
- Sensitive to alignment settings, which can lead to accelerated or uneven wear if not managed.
- Limited wet weather capability, requiring caution in rainy conditions.
Observations
- Users specifically noted the tire's effectiveness in competitive racing classes like SSM, where it offers a competitive alternative to dedicated slicks.
- The tire is frequently compared favorably to more expensive ultra-high-performance tires, offering similar grip levels at a lower price point.

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.
