Pros, cons & observations
Themes extracted from owner reviews across retailers and review sites — not the opinion of TireWheelGuide.
The Dunlop Grandtrek SJ6 receives a highly critical assessment from the user, who reports significant performance deficiencies in both wet and dry conditions. The reviewer expresses extreme dissatisfaction, citing poor handling and braking capabilities.
Cons
- Poor handling characteristics in wet and dry conditions
- Inadequate braking performance
- Overall lack of reliability and quality
The Yokohama Geolandar A/T G015 is widely regarded as a highly capable, road-oriented all-terrain tire that excels in balancing daily driving comfort with moderate off-road utility. While most users praise its longevity, wet-weather performance, and snow traction, a segment of owners reports inconsistent tread life and occasional traction issues in specific conditions like deep mud or ice.
Pros
- Excellent on-road comfort and relatively low noise levels for an all-terrain tire
- Strong performance in light-to-moderate off-road conditions, including gravel and dirt
- Impressive tread longevity for many users, with several reports exceeding 40,000 miles
- Reliable wet-weather handling and 3PMSF (Three-Peak Mountain Snowflake) winter certification
- Aesthetic appeal with an aggressive tread pattern
Cons
- Inconsistent tread wear reported by some users, particularly on heavier trucks
- Performance limitations in deep mud and heavy, rutted terrain
- Occasional reports of 'floaty' steering or lack of stability on certain vehicle platforms
- Mixed feedback regarding wet-weather traction, with some users noting slippage under acceleration
Observations
- Users of heavy-duty trucks (3/4 ton and 1-ton) report varying experiences, with some praising the load-carrying stability while others note faster tread wear under heavy towing.
- Subaru owners and light SUV drivers frequently highlight the tire's ability to maintain a quiet, car-like ride compared to more aggressive mud-terrain alternatives.
- Drivers switching from passenger-rated tires to LT (Light Truck) load-range E versions noted a significant increase in ride harshness and steering stiffness.

Yokohama Geolandar A/T G015
Community members generally praise the Yokohama Geolandar A/T G015 as a comfortable, quiet, and capable all-terrain tire that excels for daily highway commuting while handling light off-road and winter conditions well. It is frequently recommended for drivers prioritizing on-road manners, fuel efficiency, and mild trail or snow capability over heavy rock crawling.
“Yokohama Geolandar A/T G015 Snow performance. I'm currently running Yokohama Geolandar A/T G015's on my 2013 Subaru XV (WIP) and I live in a semi snowy area and also work in the mountains on construction sites in Japan. My co-workers keep telling me I need dedicated studless (Winter) tires but I had zero Issue with my current tires last year. I got a little stressed out and paranoid about it today when they mentioned it again, yet they have all had slippage on snow with their dedicated tires yet I had zero. Am I over thinking things? My co-workers are asses to be honest, but anyway I've attached some photos of the sort of conditions I drove in with zero trouble, yet they had slippage coming up the hill into the jobsite.”
“GEOLANDAR A/T G015 Anyone running these on 17" rims, stock or other? I have Enkei M52 rims, 17x7.5 and 45mm offset. What size fits without rubbing? 215/60R17 looks to be the closest, the only other size close is 225/65R17 which I think will be too big without a lift. I am open to other suggestions for off-road capable tires that will mainly be used on-road. K02 is out because they don't fit without rubbing, and I plan to add flaps at some point and do not want to lift the vehicle or get different rims.”
“Changing tires (General Grabber AT3 vs Yokohama Geolandar A/T G015) Halloo I am about to pick my RR next month from the dealer and I am thinking if it is a good idea to change tires. Here is the context: I am buying the RR because I always wanted to drive a truck and I love American cars in general (I also have Mustang s197 V8). In fact I want to switch from Wrangler Sahara, which is a great car BTW, however after 4 years and only 20.000 miles I know I miss more comfort. The rest of my family even more ;-) 95% of my trips is on reagular roads, city cruising. Sometimes some rural paths (no heavy offroading). My Wrangler came with Duelers, which I replaced with Yokohama A/T G015. The difference was night and day as far as wet and cold. Here in POLAND we have two seasons: it is either hot and wet or cold and wet. Winter in my area is pretty light, however I go to the mountains once a year. So the question is: As I do not know how General Grabber AT3 works, but I trust Yokohoma G015, is the change the tires worth it?”
“Anyone here running Yokohama Geolandar A/T4 G018's? Any complaints or regrets (road noise, balancing issues, etc.), specifically in SL load? Currently have the Geolandar A/T G015's on my 4th gen and am considering the A/T4's next. All the real feedback (non-commercial reviews) I've been able find on here and other forums seem to be pretty old and mostly by people without a ton of miles on them. My use case is about 90% on road with the remaining 10% on mild to moderate trails. Not a rock crawler and never will be. The G015's in SL load have been pretty perfect but I've been thinking about changing to the A/T4's next for slightly better off road performance. Main concern (aside from weight, which is why I'm looking to stay with SL instead of C) is wet pavement safety since I drive my young kids pretty much daily. I only have a roof rack, so not too much added weight.”

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.
